Baseflight FixedWing

This Guide is constantly  under construction.
Latest update 2016-08-21  

How to setup a  NAZE32 and NazeMini
For Airplane and Flying Wings for Return to Launch functions.

NOTE!

The more advanced F3 boards is not supported by Baseflight.


Magnetometer and Barometer is NOT needed for Airplanes.
A Naze32 Acro or AfroNaze  together with a Gps module is sufficient.

Connection diagram for NazeMini



Owners manual from Abusemark




Connection diagram for Naze32




Owners manual from Abusemark



Most settings is available in the configurator.
The Settings for Elevator compensation is not active though it always show zero.
That is still a CLI command if you need to adjust it..

I recommend to install the latest dev for Fixed Wing.
It have all new fixes and functions.
Install it with the Firmware flasher in Baseflight Gui

New Updated Version.
Baseflight_FW_160622

Here's video from Matthew Ogborne where he's testing FW_160622
If he had followed the recommended settings his first flights would have been much smoother.


To setup a normal Airplane with  RTH & PosHold

The latest version now  have a simplified setup.
Enter CLI mode in the Gui.

To setup Baseflight for a Airplane
Type preset Airplane and enter.

Or to setup a Flying Wing
Type preset Flying_Wing and enter

Therese commands will change the settings to suitable values to start with.
What remains is to select the GPS and receiver type you are using in the config TAB

Transmitter setup
Use the Receiver Tab in the Configurator and ensure that your transmitter
Send the channels within 1000 - 2000 range and centers 1500.
Failsafe will be triggered if the value falls below 995µs.
The failsafe threshold can be changed in cli.

Soft serial setup
I have not tested soft serial my self but i have been recommended to 
Follow this guide

Failsafe setup

The preferable way to detect a Lost connection is to program the radio to 
Stop sending PPM/PWM signals.
Or to program it to center all channel and trim throttle channel below the threshold value.

Servos

If the Gyro compensate in wrong direction when you move the plane.
Change the direction in the servo TAB.
Endpoints should be set in the Gui and not in the Transmitter.

The parameters for the Navigation.

Max allowed influence from GPS code in degrees.
fw_gps_maxcorr = 20        // Max Roll input from GPS (For Flying wings set to >=30)
fw_gps_maxclimb = 15      // Max Climb input
fw_gps_maxdive = 15       // Max Dive input
fw_gps_rudder = 15          // Max Rudder input if rudder is available

fw_climb_throttle = 1900     //  Limits Throttle during climbs
fw_cruise_throttle = 1500   // Suitable average throttle
fw_idle_throttle = 1300       //  Lowest throttle during Descending

fw_roll_comp = 100             //  How much Elevator compensates Roll in GPS modes
fw_rth_alt = 50                   //  Min Altitude to keep during RTH. (Max 200m)

small_angle  = 180            // Will allow the Plane to be Armed in any position.


GPS modes Need to be activated together with Angle or Horizon modes.










Flight Modes

Passthru = Manual flight Mode
All stabilization is disabled.


Acro = Normal mode
Gyro Stabilization is active..


Horizon = Stable mode
Gyro And Accelerometer To return the plane to level.

PosHold + ANGLE = Hold position mode
Uses Gps to Circle the point where it was activated.

RTH + ANGLE = Return to home mode
Uses Gps to return home.
Starts circling after return 

RTH + ANGLE = Auto Launch mode
Use RTH to launch the plane.
Activate before launching.
Will Climb to RTH altitude and 
Starts circling around home. 


Failsafe RTH = Emergency Return mode
Uses Gps to return home.
Will attempt to land the plane when returned.


Advanced setup of Custom servo mixer

Setup a CUSTOMPLANE

All servos can be programmed with different functions.
Baseflight Gui now have a working servo mixing tab to use.

Before it was supported by Gui i created a simple
Windows App to setup Custom Airplane
Download ServoMixer_CLI.exe

Smix = Mixer ID
Servo = OutputServo
Input = Selected source
Rate = % rate and reverse with minus.
Speed = Higher is faster.(3 gives a nice speed for Flaps )
Min/Max = Endpoints 0 - 100 // 50 = Centerpoint
AUX select =  Activate the rule with a AUX switch. zero for always active.




Create new rules
Select Output servo,Input,Rate, Min, Max and controllBox
Press Add to complete.
Add the mixers you need for your model.


Mark a rule to edit it.
Press modify to save the modification.
Organize the list and move rules up or down.
Clear the list or fix the number order with
Reorganize button
Export mixers when done.

Edit the mixers manually before exporting.
You can Copy the text and paste it in Baseflight CLI intercace.

Or select correct Comport and Send it direct to the NAZE board.
Baudrate is set to 115200.
Make sure The Comport is closed and no other programs is
connected.


A CLI window will be shown to verify the communication.
Press Back to close the comport again.
Now you can connect Your Baseflight configurator to NAZE again.

elroberto51 sa...

thank you for your "how to",
i'd like to ask something your help would be appreciated...

would a 6dof naze (acro, of 6dof flip32) do the job with a ublox neo6 gps to have the rth function?

sorry for the english speaking (french pilot)


hope you will help.

thanks anyway for what you've already done

Patrik sa...

A Acro Naze (6DOF) together with a GPS is good enough for Fixed wings.
The data from GPS is used so Mag and Baro isn't needed.
In fact i have reached better results with Gps data than from the sensors.

Good luck
Patrik

elroberto51 sa...

thank you very much for your answer, i FInally had the answer, by reading the fpvlab thread.


If I want a failsafe with rth, I have to make a setting on my receiver with enough throttle right? with horizon or angle mode activated and rth..


thank you for making this possible, this low cost autopilot is just a miracle!!

Patrik sa...

or Failsafe RTH make sure Your Receiver either stop sending pwm/ppm signal.
Or send throttle below Failsafe threshold value (980µs)
If you can't trim tx low enough change the Failsafe threshold value so it can get triggered.

You don't need to set any modes on switches.
The code handle everything when it detect failsafe.

You're right this can be a really cheap insurance..
Afro Naze ~25$
GPS ~15$

It's hard to beat!..

Dave R sa...

Hi patrick, Looking to try your code in a teksumo flying wing but I need some help, how can I set one of the aux channels to passthrough on an afromini, set gimbalflags=4 doesn't seem to work presumably because it's not a multirotor (I want to trigger some built in RGB LEDS).

I'm thinking a custom mix is the way to go with a direct output for one of the aux channels but I'm not too sure where to start, any pointers?

Patrik sa...

Hi Dave,

Custom mixer is the way to go.
First setup a mixer for the plane.
mixer CUSTOMPLANE
smix reset
smix load flying_wing.


Will load the built in mixer.
SMIX 1 4 1 50 0 0 100 0
SMIX 2 4 2 50 0 0 100 0
SMIX 3 5 1 50 0 0 100 0
SMIX 4 5 2 50 0 0 100 0

Then add 2 new to passthru AUX3 & 4 to S3 & S4
SMIX 5 6 7 100 0 0 100 0
SMIX 6 7 8 100 0 0 100 0

Dave R sa...

Thank you that worked perfectly, another question, the mtor spins up on arming despite turning on motor_stop, I'm not a a fan of this on multirotors let alone fixed wing, can I disable this behaviour?

Patrik sa...

It's a bug i will fix.
You can lower Minthrottle to 1000 to stop the motor meanwhile.

Mohd Shamshir sa...

Hi Patrick, i try to activate RTH before hand launch, but it seem my aileron will turn to max roll position, is it normal ? i'm using Ublox Neo 6Mv2 and looks like there's no issue on 3D fix and i can see 6+ sat lock, thx

Patrik sa...

@Mohd
No that's not normal.

Maybe you move the plane when Gyros calibrate when connecting the battery.
Try to place the plane stationary and start calibration with the sticks.
Elevator and Throttle Low and Yaw full left.

The servos should freeze for a second at max throws.

Mohd Shamshir sa...

tq patrick, i've try calibrating with sticks and looks like everything is fine. I launch the plane in passthru mode and climb to some altitude. I try to activate posHOLD or RTH but suddenly my plane will dive to the ground. Also i've tried to assign one switch to activate only HORIZON mode (without RTH/POSHOLD) but my plane also dive to the ground . Can't figure it out why the plane cant go stable in horizon/angle mode, please help me.

***i deactivate passthru mode when activating HORIZON or RTH switch

Mohd Shamshir sa...

ok Patrick never mind, already figure out my problem was due to reverse aileron in stable mode. My aileron go down instead of up when i lift up wing. Successfully maiden and RTH/POSHOLD done very well. Thanks a lot Patrick for your code.

Mohd Shamshir sa...

Hi Patrick, me again, i would like to ask u regarding failsafe RTH which i'd setup my acro naze32 'failsafe detect threhold' to 995, i've setting failsafe on rx which will sendind throttle signal around 992. How do i know that my failsafe RTH is functioning ?
I've try to off my tx, then aileron will go into max full roll and max elevator up for about 1 or 2 second then it will back to stable and if i lift up wing i can see aileron up (probably now in failsafe RTH mode). Is it functioning?

Patrik sa...

You can see in the Gui when Failsafe is active.
The Angle/Level will be activated.
The elevator should be set to climb.
Throttle will rise to almost Full to gain speed and altitude.

If failsafe is activated within 10 meters from home position the motor will be disarmed and climb will be aborted.
The stabilization will still be active and the Ailerons should compensate for navigating around home and descend if airborne.

It's also a safety that motor don't start att full throttle if you should switch of the Transmitter near home with the model in your hand.

Dennis Ehlers sa...

Hi Patrik.
I have a little Question about the Naze32 acro. There wasn´t a baro and a Mag on board so can i use these external sensor board? http://www.xxl-modellbau.de/BARO-BMP180-MAG-HMC5983-I2C-Board-Arduino-Multiwii-Multicopter

And where must i connect it? Am i right that i must soldering it to the SDA SCL pads? And where can i get the 3,3V.

Damn so many questions for such a little board :D


Thank you for this nice thread here.

Patrik sa...

Hi Dennis,

You don't need Mag or Baro on a airplane.
Data from the GPS is used for navigation.

Spend the money on a extra battery instead.

There's a 3v pad on the NAZE board.
Depending on Version it's next to the Led's or the usb connector.

Good luck
Patrik

Mohd Shamshir sa...

Hi Patrick, thanks for ur explanation for checking failsafe, i've try the rth failsafe and looks like everything is fine and i'm so happy with this function, thanks Patrick.

Another question, i would like to ask u regarding 'sbus' . I got new cheap radio transmitter "Radiolink' AT9 from china. This radio support telemetry using R9D receiver. My problem right now is, R9D rx only have PWM and SBUS signal and there's no PPM in this rx (R9D). For ur info i'm using acro naze32. So if i use sbus to naze32, is it i can still use GPS an telemtry .

Patrik sa...

I run PPM on everything and have not tested Sbus.
But if you can set it up on softserial it should work.
Here's a basic instruction on Sbus setup.
http://www.netraam.eu/nazewiki/pmwiki.php?n=Howto.HookupASpektrumSatellite

It seems in basic config GPS and Sbus share Uart.

Mohd Shamshir sa...

Hi Patrick, i got problem when trigger RTH or PosHold, there is no action at all, the plane go straight without turning to launch location. before this everything seem ok when using PPM mode but after i change to PWM looks like RTH and PosHOLD not functioning. Already change back to PPM mode but still RTH and PosHOLD not functioning. I've check switch for RTH and PosHOLD is in correct position (angle/horizon + GPSHOME) and sure i've to wait GPS to lock signal before launching the plane. Any idea ?

Patrik sa...

I have had some other reports of same bahaivour.

Test to use this older version.
http://panoramaic.se/Files/baseflight_NAZE_ezikiel.rar
I have changed version in the Blog post to.

Dennis Ehlers sa...

Heyho today i tryed the old Version which you have post. If i activate the rth the plane moves straight in one Position away.
Doesnt work :/ but horizon and angle worked very well:D

Any idea??

Mohd Shamshir sa...

Hi Patrick, already test old version and RTH function success, thanks a lot.

***Dennis, the old version post by Patrick is to resolve the earlier version which RTH was functioning at first but suddenly had an issue of not returning to launch location. If you have the same behavior then the old version should resolved the issue. If not then u have to check your configuraton.

Dennis Ehlers sa...

Hmm i follow the Guide step for step. After flashing ezekiel i have the Problem when i change something and save the naze doesnt reboot. So i have to Save and disconect it by myself.

Did i have to Set all things for Navigation in the cli?? Rth alltitude etc?

Patrik sa...

Hi,
I added a Note in the instructions.
The Airplane Tab is not supported In the Ezikiel version ALL FW_Nav settings must be made in CLI.

Jussi Hirvonen sa...

Does this firmware work with F3-boards like TornadoFC, Dodo, SPRacing F3 etc? Or maybe F4 like OP Revo or TauLabs Sparky 2.0?

Mohd Shamshir sa...

Thanks Patrick for mentioning fw_nav to be set in cli but for my setup i just leave it default the value and everything looks fine.

Dennis, if you follow the guide i think rth should work properly, there must be something u miss out. All setting i made in cli
My setting as below:

mixer AIRPLANE
feature PPM
feature GPS
feature FAILSAFE
feature FW_FAILSAFE_RTH
feature MOTOR_STOP
set maxthrottle =2000

mode selection switch i assign
RTH = angle + GPS Home
PosHOLD = angle + GPS HOLD

If u assign PASSTHRU mode then make sure don't activate PASSTHRU when u activate RTH or PosHOLD

Also u have to make sure GPS signal is lock before u can launch your airplane and i dont assign any switch for ARM (use stick RUDDER to ARM or DISARM)



Dennis Ehlers sa...

I have the same settings.
But i dont activate Mixer Airplane in the CLI.

passtrough was on a switch in position 0 Angle in 1 and angle and RTH on position 3

PosHOLD i didnt have.

Arm Disarmed was on another switch
I launched my Airplane with 12 sats

I will test to activate the airplane Mixer with the CLI.
My Naze wont to reboot when i save anything.

after reboot the gui doesnt give any response and i must use the disconect and connect button.


THX for your help :)

Unknown sa...

Will the rth feature work for planes without ailerons? Like easystar, which is rudder+elevator only. Thanks

Pedro Albuquerque sa...

Hello Patrik and everyone, after reading this blog of yours that a friend pointed me out (thanks Rui), I loaded baseflight (GUI 0.68.3) to a flip32+ (10DoF with baro and compass) controller from bangood.

I moutedit on my airplane FT Slinger (from flitetest design), motor, 2 ailerons, ruder and elevator, using customplane mixer.

I have also connected a GPS (Neo-6M) configured for Uboxat 58600 baud.

On the bench everything worked fine, I have configure passthrugh, acro and horizon (no GPs relate to start first test flight), and surfaces moved as expected.

I have lauched the airplane and motor imediatly stopafter take off (landed a bit hard), seconf flight after getting back to the bench and not being able to simulate the failure, took-off flyed as expected in acro, hroizon and passthrought, yet another motor stop forced another emergency landing.
Third attemp,same thing another motor stop.
Feels like a software reboot.
Last one the reboot was not complete, as wil plane one hand after landing , all surfaces started to move one at a time, like glitch but only one surface at a time in a circle, and no response to radio input.
Motor not moving.
switched to desarm (switch assigned) and back to arm and motor started work normaly as well as all surfaces.

A imediaty testes with direct connection of servos and ESc to RX, and flown without failure.

My assumption is that the problem lays on the controller/software.

have you heard of similar problem ?
If so,is there a known fix ?


Patrik sa...

I have not heard about that problem on a NAZE.
But on the MWii 8bit Mega boards.
It can occur if the BEC can't supply enough power to run the controller.
Or if the ESC gets too hot and cuts.

When the controller reboots and is ARMed it can lockup in the boot sequence.
If you disarm the controller will continue the boot sequence.
But the servos will be wrong calibrated and the plane can only be flown safely in Pasthru.

Tim M. sa...

Could you please answer the question about flying the plane without ailerons?
If the RTH does not work in rudder+elev configuration I'll install the aileron servos just for it, although I prefer the default configuration for FPV/Video purposes

Patrik sa...

@Tim

I have not tested it myself.
But i know others who have connected the Rudder to one of the Aileron outputs.

Patrik sa...

@Dennis Ehlers

If the Controller is ARMED you will have similar issue.
Settings isn't saved and controller freezes in the Bootup.

It's the only thing i can come up with besides HW faults.

Pedro Albuquerque sa...

@Patrike,

Thank you for your clue.
Yet I believe I found the reason for reboot of the board.
I Flewit without controller (Flip32) i.e., connecting surfces and Esc directyto receive and there was no failure.
I replaced the ESC by a Blue Series from HK,and there was no failure again.

My bilieve is now that the frequency of the motor PWM is too high form the previous ESC (HK 30A), and it looses sync causing shorts on motor output, this leads to spicks on puwer line that feed the board.

I will test again the previous ESC, this time with lower PWM frequency and let you know (I believe there is a way to set this in baseflight).
I'm sharing this beacuse I believe most of us that already fly quad already know this problem, but those that are just adding this to old plane (like me) using old hardware my face the same problem.

Schalonsus sa...

Would be great if max value of fw_rth_alt would be higher like 1000m. So this AP would be suitable for long range missions.

Øystein Ellingsson sa...

Hi Patrik,

Love the custom firmware.
Could you possibly share the source for this?

Thanks,

Can this connect to bluetooth module to be able to connect to android app like ez gui or multiwii congigurator for easy PID tuning?

Thanks

Patrik sa...

Yes it works with Bluetooth.
Even with long range telemetry links.

Giovanni Perillo sa...

Hi Patrik,
first thanks a lot for this useful guide...

I'm trying to use a naze32 on my bixler 2 and I have a simple question. I'm using a PWM receiver on the plane, and the original idea is to GPS. how can I connect the GPS? I mean, I know that I should connect it to the channel 3 and 4 but how are the channel remap? do I need to manually remap them? is it also possible to use the mimim OSD with it?

thanks in advance for you help..

Regards

Dennis Ehlers sa...

"When GPS feature is enabled, channels 3 and 4 are are used for 3.3V GPS connection.(3:TX, 4:RX). with CPPM receiver, these are normally unused, with standard receiver, connect AIL to 1, ELE to 2, THR to 5, RUD to 6, and AUX1/2 to channels 7 and 8."

You can use the minimosd but you have to connect it at the bottom. There are two holes named tx and rx where you have to solder some pins. 5v and gnd get from the pins s2 because they are free.
But if you want to connect the usb you have to disconnect the tx and rx from the minimosd off the naze.

I hope this will help you and you understand what I mean :D

Dave R sa...

Hi Patrik,

I've re-located my GPS unit and now get a reliable 3D Lock, however I can't seem to find a CLI setting to reduce the diameter of the circuit when holding position or returning to home.

As it is a flying wing I have increased the GPS correction angle to 35 and reduced gps_wp_radius = 50 but it doesn't seem to have any noticeable effect, any thoughts, should I increase the GPS angle to tighten the bank?

Patrik sa...

Hi Dave,
There is no real setting for diameter around home.
Only a limit in Max banking.
fw_gps_maxcorr = 45 Is the tightest circle you can get without Rudders.
fw_roll_comp Adds Elevator based on banking angle and can also help to tighten the circle if you increase it.
Default value is 1:1.
As observed... In Baseflight, gps_wp_radius have no effect at all on Planes!..

brooks shield sa...

Thanks Patrik.

Currently im setting up my flip32 and gps, what should be the baud rate for gps, im using Mini gps Ublox7 from aliexpress.

Currently factory setting for gps is 9600 and the flip32 com baud rate is 115200.

Thanks.

Paul Hammond sa...

Hi I have installed this build, but am having problems. Randomly the plane stops responding to the controls and it crashes.

Im using a flip32 mini board.

I thought it might be the 5v bec browning out under load, so i changed it to a 2a version and it still happened again today.
Yesterday the ESC went full throttle on the crash and the only way to stop it was to remove the battery. Today it didnt go to full throttle but the flip32 was locked up. both of the red and white leds on the board were lit. The Frsky RX leds was responding as expected, but the flipe32 was locked.

Any idea why?

I have my GPS cable running next to the motor wires, could that cause issues?

Patrik sa...

Hi Paul,

I don't think GPS cable running next to the motor wires is a problem.
One thing that can be a issue with FRsky is the 22/27µs frames!.

If you have old FW in the frsky and use more than 2 AUX channels the PPM can loose sync.

One other thing can be If any of ch 1-4 is below Falsafe threashld.
Then the FC can activate Failsafe!

Not sure what else can be the issue!.

Paul Hammond sa...

Hi Patrik,

Thanks for you reply.

I did some more investigation on the bench and found that the problem is easily replicated but I still don't know the reason.
When the GPS is connected, the flip32 WILL freeze, always less than 10 mins. Even when it is sitting on the bench, no extra power being used (by servos ect..).

If I repeat the test but with with GPS unplugged it works normally and doesn't freeze at all!

When I get a freeze, the LED's on the Flip32 will go red (i think) and is stuck on, There is no control through the radio link and no USB communications. The only way to get it to unfreeze I need to cycle power.

I hope you can help, as I really would like GPS working on this plane.

Thanks
Paul

Adlison Oliveira sa...

Hello PatrikE

I was a big fan of your Multiwii version now I'm going to try this in a 1.65m wing, hopefully this weekend :)
I have two questions:
a) why did you use baseflight and not cleanflight which has a few more interesting features?
b) Do you know if I can add a bluetooth to a softserial? I can do that easily on cleanflight, that's actually my reason behind the first question.
Thanks a lot!

Patrik sa...

I have not seen any freezes on my Naze boards both Acro and Afromini.
I can leave them running on the bench connected with USB and no servos.
Often several days in row with Gps connected without problem.
I mostly use remote desktop and like to have the FC connected to the Dev Pc.

The LED usually go on if Failsafe.

Patrik sa...

a)
Baseflight is similar to MWii in code and was easy to use.
Cleanflight also had a reputation of behaving strange on Fixed wing.
That's why!

b)
I have not played at all with the softserial.
But it should work i think.
Baudrate is limited though!.
But i guess you know that better than I do. ;)

Adlison Oliveira sa...

Thanks for the answers.
I know how to activate the softserials, as a matter of fact, I already have one forwarding FrSky telemetry. My problem is, I cannot make one send the baseflight protocol so I can use ez-gui to configure it like I do in cleanflight. If I connect to a "real" serial port works fine but the ones I have are already been used by gps and OSD.
Hmmm... may I should try the OSD trick that APM uses, not wire the TX to the OSD. Don't know if works but...

Adlison Oliveira sa...

Just to answer my own question, no, connecting just the TX like in APM does not work so, unless I figure out how to use bluetooth via softserial, it is a no go unfortunately.

Unknown sa...

Set soft serial to output msp at a lower baud (whatever your Bluetooth is set to, I use 57600), drop your main baud also, and should work

Adlison Oliveira sa...

Yes, I know that, I've done this in cleanflight but I can't find the right sequence of commands to do that in baseflight.

Garry Kraemer sa...

Patrik,
I am using Cleanflight in a Flip32+ FC. I have a Taranis TX & RX. It is a nitro powered airplane. mmix and smix are NULL sets. CF mapped the servos to outpins 3 thru 6. I would like to move them to 1 thru 4 since I do not have a gimbal or electric motor on pins 1 & 2.
Is this possible. It appears that CHANNEL_FORWARD or servo_tilt is causing the servos to be mapped in a +2 order. I have used 'dump master' and I don't see anything strange.
I had a terrible time locating which output pin went with each servo!

Thanks

Garry

Joakim Holst sa...

This is amazeballs!
Just tried your firmware with my scratchbuilt ugglan from boopidoo =)
It flies beautifully with your settings that came with the .rar file, and that with a sub $100 fc and gps. Now I'm going to add canards to it and learn how the free servomixer works.
Ha de bäst!

Adam Dudkiewicz sa...

Hi,

Thank you for you firmware.

I've installed it on my naze3 rev5 set up everything as per instructions. After launching the plane I tried position hold and it worked beautifully. Then I flew little further to test RTL, again it worked perfectly and the plane returned home and started circling around my head. I was amazed how well it worked and kept watching through my goggles for a minute or so when suddenly my OSD said DISARMED and the plain started heading vertically into the ground.... tried disarm and re-arm it with the switch but nothing helped and I totally lost control over the plane. In the result the plane is totaled and the battery went on fire under the impact.

Is there anything obvious I missed or did wrong?

Thanks,
Adam

Patrik sa...

Hi Adam,

I'm sorry for your model.

It sounds like the code behaved as it should until OSD said DISARMED.

There's only one scenario when the code disarms in air.
If You loose RC control the FC will disarm over home to initiate a descent.

In your case it sounds like you had a power drop that caused the FC to Reboot in Air.
And the plane can´t recover after FC is rebooted since the Gyros calibrate during movement.

It's not easy to know after the battery burned it it was faulty before.
Servos can also fail and short the BEC.

I have had some Brownouts on models too.
It normally results in a spiral and crash.
Large capacitor and separate Bec for the FC is best.
But if Battery dies there's no return....

I hope you keep up and give it a new chance.

/P

Hi Patrick,
The battery was almost fully charged and died from the impact. Up until the impact my telemetry didn't give me any warnings or alarms. I suspect it could have been a voltage drop caused by current drown by servos. I did have voltage drops before that were causing my gps/osd to go off and on but I rectified it by powering the gps and osd module from a separate bec. I didn't have the FC to reboot itself before though.
Well I might give it a go again at some point on another plane as your code worked really well.

Thanks,
Adam

I need help friends, Patrick firmware works perfectly on my FX -61 wing. no GPS and no OSD .
I need to install the OSD , but I have a mini and precise naze32 enable MSP .
In Cleanfight firmware and iNAV can make the OSD function , but these firmware has a problem that when accelerate the servos wing move alone.
Does anyone have any solution?
Sorry my poor english (google translator)

Chris sa...

I just wanted to say thank you so much. I have spent literally days trying to get clean flight and then baseflight to work with my fixed wing. What selfish people that they do not tell you their software does not work standard with fixed wings, even while they claim it is a "stable" version and offers fixed wing in the menu. Thank you again for your wonderful work. Chris Hachmann

Chris sa...

Patrik, do I want to use "in flight calibration"? I am putting this on a Parkzone Radian Glider and I was wondering if the PID settings were too low as the plane tends to be unstable at times in the wind. Thank you.

Patrik sa...

The PID's i recommend here is suitable for most Sport planes.
Slow flying planes may need higher P values to compensate harder.
You will notice when you go to high because the plane will overcompensate and Wobble slightly.

Chris sa...

Thank you Patrik. Yes, I increased the P values to the movements I used to see when I flew it with a Lemon 3axis stabilizer. I guess the I and D values can be left alone?

Chris sa...

Hi Patrik, The hex file is working great, but I am having a terrible time getting the RTH to work. Baseflight mode selector was set Horizon, Mag, RTH. But the plane turned away and tried to go away. Tomorrow I will try it with just Angle+"GPS Home". But I notice that the "GPS Home" does not turn green in Mode Selector as does Horizon when the box is selected. Is this part of the problem? Why do the GPS features not turn green in mode selector when selected? I am showing the GPS is locking on many satellites in Baseflight. Thank you. Chris

Chris sa...

I set it up as Angle+RTH and the plane is still flying away. What am I doing wrong?

Patrik sa...

If the HOME don't turn green in mode selector it's something wrong.
Minimum 5 sat is needed for FIX but for a reliable function you need >6-7.
Home Position must be set.

One more thing to remember is if you select Angle + GPS Home.
Passthru will override GPS modes.
Never use BARO OR MAG modes on planes.

I have a newer testversion you can use now.
There Passthru no longer override GPS Home.
panoramaic.se/Files/Baseflight_FW_160622.rar

Chris sa...

I noticed something very odd that maybe explains what I am doing wrong. In setup the Arrow for the plane (quad) is forward (if I lift the front of the plane then in baseflight I see the front of the Quad in Baseflight goes up), but somehow the direction North and South are reversed. I re-calibrated the magnetometer and it made no difference. I tried a different Naze32 and I see the same issue. The board is mounted with the mini-usb toward the back of the plane.

Are there any other changes in your new hex file?

Thank you.

Chris

Chris sa...

I think I give up. I prop came loose at one point during a flight today and the plane landed behind a hill. I must have lost signal b/c RTH was initiated and when I got to the plane the motor was spinning at failsafe throttle, elevator was up, and rudder was turned. Shouldn't RTH disable automatically when the plane is on the ground? It seems the plane did not know it was on the ground and was trying to get to it's RTH altitude. If the prop had not come loose then I would have fried the ESC and/or motor. Do you think I would have better luck with PixHawk?

Chris

Patrik sa...

The flight controller don't have any land detect!
And it don't know that the prop have came off.
It only turn off engine when it returned home in Failsafe RTH.

But you are right there should be a detection if the plane is static for more than xx sec during Failsafe to prevent burned electronics.

About Pixhawk..
I have never looked at it and can't answer on that.

The new Hex file only have some minor changes but the Passthru priority is main diff.

Chris sa...

Maybe RTH should not enable under a certain altitude, say 4 meters off the ground. At low altitudes you might be behind trees, or you might be getting too close to people to enable throttle (especially given the inaccuracies of GPS, you might be only a meter or two meters off the ground with error of measurement). So a parameter of RTH at under 4 meters is maybe just motor shutoff and the 1 degree glide angle. Can you put that in the code, or tell me how to do it and I will put in the CLI for my own flying. Thanks. Chris

Patrik sa...

I guess you could add a condition with min altitude here.
https://github.com/EmilsPa/baseflight/blob/Dev/src/fw_nav.c#L143

But remember if you fly from a hill you nay fly below Home pos and then Failsafe RTH always disarm in that case.

brooks shield sa...

tested with delta wing but encountered with issue, upon throttling left wing also was jerking

Patrik sa...

Sounds like High PID's or vibration from Motor/Prop!

Good starting values for that type of planes is.
Gyro P=1.5 Roll & Pitch
TPA = 0.90

Patrick Nelson sa...

I'm a bit unclear as to how to ask questions. I hope this works.



When entering "fw_gps_maxcorr = 20" in the cli I get ERR: Unknown command



What might I be doing wrong? Please can you let me know.



Also, when downloading and installing the 10 April rar file after unzipping it, it's actually still the 3 April one in hex.



Thanks!

Chris sa...

I disabled the RTH feature and the failsafe feature completely in baseflight. I thought this would prevent any future problems. But today at the field, for some unknown reason from about 100 ft my plane's control surfaces all went into full deflection resulting in a spiral into the ground. This happened on the 4th flight of the evening, it had been flying fine. This does not make any sense, though I know the Naze32 likes to lock the surfaces momentarily after it is disarmed. Perhaps I gave too much rudder in the flight and the board disabled? Very odd.

Patrik sa...

You should not use Arm with sticks.
It's safer to use a AUX switch.

But it sounds like you encountered a brownout!.
The BEC can't provide enough power to drive Naze + GPS + OSD + servos.
This results in a Reboot In Air!
It happened twice for me before i realized why it crashed.

The best solution is to use a separate BEC for Servos and FC so the other electronics dosen't brown out when servos Work hard.

You can also use a large capacitor >3300µf to the FC.

Gede Santosa sa...

Hi Patrik,
I tried to use your latest 160622 firmware and succesfully flash it to the board.
The problem is when i click connect on the configurator, it give warning as the firmware was not supported, looks like api version problem, i use the latest betaflight configurator

Could you please advise how to solve this problem ?

Try Baseflight configurator instead ;)

Hi Patrick!

Thanks for your great work. We really need this working cheap FC for fixedwings.
I tried your fw on my Skywalker X5 with Flip32 board.
After a few parameter tweaking for me it worked amazing and stable. Really like the RTH.

May I ask your boosted source code available somewhere?
I would like to add more telemetry features in it.

+ { 4, INPUT_PITCH, 50, 0, 0, 100, 0 },
};

Is it because of this servo throws reduced in half compared to Jan 6 2016 firmware?

Thanks!

JD FPV sa...

No servo response from the naze32 board. Using baseflight on a rev 5 board. Follow every step and it does not work. Any suggestions?

Patrik sa...

The change of servoMixerFlyingWing[] was done to keep the symmetry between Ail & Elev.
It also results in a reduced Max throw as you guessed.

Patrik sa...

@JD FPV
I would guess you have uploaded the Stable 2015.08.27.....
That version has a Bug that break the servo function.

Use my Dev version instead.
http://panoramaic.se/Files/Baseflight_FW_160622.rar
Run the preset Flying_Wing CLI command.
Or preset Airplane.

Martijn Hoeke sa...

Hi Patrick,

Would like to use your software on a twin motor plane with differential thrust. I found you made a custom version "baseflight_NAZE_Twin_RTH.zip" in 2014. http://fpvlab.com/forums/showthread.php?27854-NAZE32-for-fixed-wing&p=597191&viewfull=1#post597191

Should I run this 2014 version or can I setup differential thrust in the most recent version of your software?

Thanks!

Patrik sa...

You can use the latest version.
You can activate vector trust in cli by setting the parameter to 1.
If it compensate in wrong direction swap the motor outputs.

Good luck

Chris Rogers sa...

I have installed your firmware into a Naze 32 6dof and am having trouble setting up GPS modes. I have both a GPS and a Bluetooth adapter wired up and they both appear to be working with your firmware. When I setup my GPS RTH and GPS Hold, I am also setting up Horizon on the same position as you recommend. The problem is when I flip the switch only Horizon mode turns green and nothing I do will make the GPS Hold or RTH light up green. Have I missed a setup step?

I attempted this unsuccessfully in Cleanflight before I found your firmware and while both modes wanted to make my Blunt Nose Versa Wing into a lawn dart... I was at least able to activate them and they both turned green.

Hi Patrik,

I'm new to fixed wings, and have just bought a SkyCruise 2400 which I will like to equip with a Naze32 with your firmware. I have read through your instructions and the comments field, but I can't see anything about flaps. will it control flaps as well or is that up to me to control them? and what CLI command do I need to use?
Best regards
Villy

Patrik sa...

Cki commands to start with
mixer CUSTOMPLANE
smix reset
smix load AIRPLANE

Then you can add flap function on the Ailerons in Servo Tab

Hi Patrick, I just received my naze32 and flashed Baseflight_FW_160622 onto it. Everything works fine until I use preset Airplane. Then the led turns to red after a while and the receiver signals are not doing anything anymore. While if I reflash it with full chip erase, then everything works normal again.

Martijn Hoeke sa...

Hey Patrick,

Thanks for the reply. Could you help me with the CLI command for differtail trust?
I found these differential thrust setting for Cleanflight:
mmix 0 1.0 0.0 0.0 0.3 # Left Engine
mmix 1 1.0 0.0 0.0 -0.3 # Right Engine

Can I just replace "mmix" with "cmix" to make this work with your software?

Thanks!

Patrik sa...

set fw_vector_thrust = 1

Is enough to activate it.
If motors compensate in wrong direction swap the wires.

Goog luck

Patrick Nelson sa...

When I take off in Horizon mode the flying wing rotates and starts flying upside down. Any ideas?

Hartono Sutanto sa...

finally with M8N i manage to get a 3D fix. the GPS unit must be placed quite far away from the fc or otherwise difficult to catch satellite. The M8N is updated with the 3DR configuration file to get a better result. Time for testing.

Hi Patrik!

Thank you for developing this software, it looks very interesting! :-)

I'm a multirotor guy with so far no experience with flight controllers on fixed wing (however, I can fly fixed wing, and a have knowledge about multirotors, betaflight etc) . I'm planning to build an inexpensive FPV plane with RTH capabilities. I hope i not bother you to much with this burst of questions!

1. Do you have any links to recommend to start reading for a beginner like me? I have read all comments on this page, and are skimming through the "Naze32 for fixed wing"-thread on fpvlab.com. Are there any else reading material to recommend?

2. What naze32 do you recommend for this application? I guess the cheapest I can get now is a rev6 from banhgood, but I know that there have been tuning problems with the MPU6500 chip on multirotors. Does this problem apply here to?

3. Do you know if using FrSky X4R-SB in CPPM mode work good? i read somewhere here in the thread about sync problem with to many channels. I plan to use EU-LBT firmware.

4. I have seen threads about problems with planes waging (or rather S-ing) on RTH, or having a unreliably RTH over all. Is this a big general problem? is it related to pid tuning or is it more of a hardware problem?

5. What GPS shall is choose? does update rate or any other factor a big impact on for example course stability?

Thanks in advance!

Roy sa...

Hi Patrick,

I have to say your solution for small wing works superb. It works better than a much higher budget solution.

One thing bother me a bit is the servo throw on Angle mode or Horizon mode. It seems that the servo throw was limited. quite a bit. In Rate mode, I am ok if I set the rc_rate to 2, the servo throw is then smooth and offer me full deflection. However, In angle mode, it is very limited. In Horizon mode, the deflection can go high if the stick moves to the edge, however, the transition is not smooth at all and cause a bit jerky on the flying when horizon mode is engaged. And setting that can simply in all mode map the TX range to full servo throw on the Angle mode ? On the servo tab, I have set the min and max corrected and they are corresponding to the full stick movement.

Thank you

Roy

Hi guy's,

I have a bit of a problem i can't tackle:
I have a naze board with patrik E flying wing firmware on it, it's hooked up correctly with a rx D4R-II in ppm ch3 and ch 4 signal jumped, in the receiver tab all the channels show up, on ch 5 i made a switch for arming on ch 6 the flight mode 3 pos switch, all the ch ( 3) move but i can't get the aux ch to move, on the ch mapping of my taranis ch 5 and 6 move from -100 to 100 what am i doing wrong. The - range is 1000 mid range 1500 top range 2000 throttle ch is 995 on full cut off.

The transmitter is in TAER1234 and in baseflight receiver yab as well.

Question 2: do i have to remove the elevon mix from taranis just like with any other fc.?

Appriciate the help😜

Hi Patrick!

I use your FW a few month ago on my V-tail plane. Thank you again. I really like it.
RTH is working fine, but the GPS HOLD mode is not working in the air.
If I test it on the ground FC switch to GPS HOLD mode and the EZ-GUI show it also.
In the air when I switch to GPS HOLD mode the GUI only shows angel mode and the Plane not circling. While the RTH it is working in the Air.
CAn you help me to find out what can cause this? What is the difference in the RTH and HOLD mode?

My other question is how can I test the FailSafe RTH safely? (I still not enough brave to switch of the my Taranis during the flight.)
I never fly to far, but I have to know the Plan will come back to me in case of trouble.
If it is in FailSafe RTH I will get back the control when the Plane is close to me?
Our the Plane will land automatically anyway?

Hi.

Two short comments

- Backups - Restore [From File] and Backup [To File] works, but mixes the settings in MODE SELECTION. Better to do a dump in CLI and save the output. Restore by putting the dump in command line and save it.

- Had my CRIUS CN-06 v2.0 GPS set to 57600/5Hz and NMEA protocol. Better to use the description I found here https://github.com/iNavFlight/inav/wiki/5.-GPS--and-Compass-setup in chapter UBlox GPS manual configuration

Now I see Satellites Signal Strength and can perform a Deviation Test.

Dani sa...

Whats the difference between acro and passthrough?

Thanks you so much for making this awesome guide!

Patrik sa...

In Horiz/Angle modes the throws is limited by Angle P-term..
Increase P or the mechanical throw on linkages.

The Radio mixer should be setup without mixing between channels.
That's the standard for all models.(Copters and planes)

Failsafe can be activated if ex. throttle channel drops below failsafethreashold.
Change the throw on throttle so you can trim it to trigger the failsafe.
Then make sure RX is programmed to trig failsafe.

@Dani
In Acro mode Gyros compensate and passthru is totally unstabilized.

You need to calibrate Accelerometer with the plane level.
And a Gyro calibration before takeoff is recommended.
It's easy to shake the plane while connecting battery.

@Hartono
There's two possible scenarions.

Either there's some setting in OSD to correct it.

Or Your Naze board can be mounted reverse.
The Home arrow uses Magnometer as default in MwOSD.
Baseflight use direction from GPS for navigation.


Uou should use theese settings in MwOSD

Hej Patrik! Thanx for your work on the Fixed Wing software. I'm migrating a few Naze32 rev5 from quads to Fixed Wing and the first one is almost ready for take off using a PopWing 900mm / Teksumo using a r410X PPM Rx and a uBLOX 6M GPS.

Three questions:

#1 I have noticed that when I'm using the CLI, the commands does work but it the UI freezes and a disconnect & re connect is the only way to restore contact. Is that a known bug?

#2 You mention the flight mode Acro = Normal mode - Gyro Stabilization is active. Is that when no flight mode is selected like for a quad?

#3 How much modifications have you done to the BF software, are you still developing this fork or is it considered a finished and closed project?

Looking forward to test the software on a maiden any day now.

Tack och trevlig helg!

Hi Jan,

You can use a Naze32 6DOF.
Or a NazeMini like in the pictures in the top.

Hello,

I am very interested by a F3 board, is it planned to have F3EVO board supported by you FW in order to have RTH on fixed wing with this board too? if yes when is it expected? Thanks a LOOOT for your work!
Best regards,
Pierre

As much as i would want i don't have the knnowlage how to port the code to F3 cards.

Sorry.

Try iNav if you want to use a F3 card.

i have to say your wing software works perfect...

still i got 2 questions.

1 - can i change the throttle speed when i activate rth by a switch.

2 - is inair callibratie working and how does it work?

greets from ed

fw_cruise_throttle controlls the rth speed.

In air calibration should work like on copters.
That part of the code is common.
It's nothing i have tested though.

Hello patrick .. I mounted the naze32 on my Teksumo flying wing. It works all well, RTH,,Hold position, and flies very well in Acro and in Angle mode.
But when I switch into Horizon mode, he turns to the right and becomes almost uncontrollable.
Why?can you help me?
Thanks for the work you did!!

I'm wondering if something changed in Baseflight recently - I simply flashed your latest firmware and then typed "preset Flying_Wing" - the CLI interface didn't display any feedback. I waited for a while but couldn't click any tabs. I eventually hit disconnect and now the board won't connect or allow re-flashing the firmware.
I repeated the same process with another board. Both were brand new, now they appear useless.

Forgot to mention that the boards I'm using are latest rev Afromini Amaze boards acquired directly from Abusemark. In the past, I've successfully used two of these boards with the same hardware setup and process.

The code has not changed since last summer.
Try to short the boot pads on the FC and flash them again.
Select full erase since some settings can prevent it to boot.
I have had some afromini that behave like that to.

OK, thanks Patrik, I'll give that a try. My first thought was that Baseflight changed somehow, making the "preset" commands break. I write iOS apps, so I'm always suspecting changes to the platform ;) I've had a great time with your firmware so far!

I get the same result with the boot pins shorted, selecting "No reboot sequence" and "full chip erase." It says "No response from the bootloader, programming: FAILED"

Hi Patrick. I have a Flip32 All In One (Pro) Flight-Controller V1.03 FC. One of the signal channels is dead (motor 3). So I have to change the smix. I'm still waiting for my flying wing so i can't test. Is the only thing I have to do this?

mixer CUSTOMPLANE
smix reset
SMIX 1 5 1 50 0 0 100 0
SMIX 2 5 2 50 0 0 100 0
SMIX 3 6 1 50 0 0 100 0
SMIX 4 6 2 -50 0 0 100

The second thing is. Uart1 is switchable and is used for usb/osd. softserial2 is soldered to a current controler.
I use the uart2 for gps and softzerial1 for telemetry.
Is there any chance of using a bt modul for setting waypoints?

Patrik sa...

I have the same board in a plane.
You can use Smix like that to address the servos you need.
It's a zero missing in the last line though.

I have never used softserial on baseflight.
If you find something out please share.

Waypoints is not implemented in Baseflight.

Just to follow up - after trying a new FTDI board and having the same issue, then trying to set up a third, completely different board, and being unable to flash the firmware, I realized that the issue was in the cable I made to connect the FTDI board to the FC.

Carry on, nothing to see here! :)
