Hello! I have an issue on my Matek Wing H743, on ArduPlane 4.7.0 beta 5, my motor when he set as “Throttle”, not working in TAKEOFF. Parameter “THR_IDLE” not working too, and when board its ARMED - motor still on 0% Throttle and didn’t spin. When i use hand launch he too stay still and didn’t spin. On any other modes motor work’s fine and starts spin when i use joystick, i tried set MINACC to 0 m/s, but still my motor doesn’t respond and don’t want to spin when is ARMED. On ArduPlane 4.6.3 release, TAKEOFF works fine, and always reacted on my hand launch, without any problems. Seems ArduPlane 4.7.0 have an issue with TAKEOFF mode on Matek Wing H743.

I’d like to clarify that TAKEOFF never had any issues with this flight controller before version 4.7.0. It seems the firmware is missing some driver for this mode, and the strangest thing is that even the fixed THR_IDLE parameter essentially doesn’t work, and the motor never starts. This issue existed in beta 4, and it remains in beta 5. It’s as if the accelerometer doesn’t work in TAKEOFF mode in this firmware. Even with MINACC is - 0 m/s, the motor doesn’t even think about starting.
I’ve been flying for a few days now, most recently today, using the Matek H743 Wlite and fw 4.7.0beta5. I launch the fixed-wing planes using TAKEOFF, and it works perfectly. As Mike @nspector mentioned, it would be helpful to have a *.bin log file.
Hello! Here is log file, i just armed on ground and tried simply throwing it a couple of times, but as usual, the motor wouldn’t start. However, everything worked fine in other modes: FBWA and STAB.
I also noticed that in my flight program, the messages tab says the flight controller is constantly restarting, and I see repeated messages about ChibiOS and ArduPlane 4.7.0 beta 5. However, in Mission Planner itself, nothing similar appears in the messages category.
Edit: I noticed that everything works on the modded firmware 4.6.3, but not on the original firmware. Does TAKEOFF have any additional checks? Previously, I had it working with just a push, even without GPS or Compass.
Yes, i know, but this isn’t problem. TAKEOFF Initially, it works correctly only with GPS; to make it work without them, you need to edit the firmware, which is what I do.
The TAKEOFF mode won’t work without a GPS. I suggest you set ARMING_SKIPCHK back to 0 (don’t skip the checks), so that you are alerted by things that should be blocking your arming.
In your log you don’t have any GPS lock, so TAKEOFF will never un-suppress the throttle.
Thanks for answer! Yep, this mode works only with GPS, when i use moded ArduPlane 4.6.3 versions, already had a different code for this mode. I’ll be changing the TAKEOFF mode code so it works without GPS.
