I just ran into some troubles trying to get my fixed-wing aircraft to work again.
After I had a failure of my rudder during flight I tried to figure out why and then none of my servos responded anymore (lukily on groud allready).
I'm using a PX4 with the Ardupilot Plane-firmware 3.7.0.
I have a single motor with a MULTIPLEX BL-20 SD-L (ESC).
The Problem I am having is as follows:
When powering the Pixhawk the ESC starts beeping periodicly. When pressing the safetyswitch I get a faster beeping (~5 beeps/sec). I then have no control over the servos or the motor via RC (cannot arm it). Even without arming I should be able to at least get a reaction from the servos.
What I have tried during my 2 weeks of total frustration with this problem:
-radiocalibration (~thousend times)
-checked all components of my assembly for any kind of error
-bought a new Pixhawk
-bought a new ESC
-calibrated the ESC manualy (using the RC and the reciver with the ESC connected without the PX4)
-much more things which I allready forgot
To me it seems finally like the ESC is not calibrated properly. The instruction of the ESC says, that the beeping meens the ESC is not gettin a 0 throttle signal.
To calibrate the ESC with the PX4 I tried to do so with a quadcopter-firmware uploaded onto PX4.
This failed probably since its a wrong type of ESC for multimotor aircrafts.
Does someone know how to calibrate the ESC on with PX4 and the plane-firmware ?
Does someone have a solution to the problem!? I would prefer an comprehensible one but after 2 weeks I would take a magical solution as well!
Did someone have this problem allready? I didn't find it in the other topics.
I hope for a hint and thank you in advance!
All the best,
