Hi,
I try to setup a bit different Wild Thumper 6WD but with the same problem. Maybe anybody can help.
Hardware:
Wild Thumber 6WD
T`Rex Controller (in RC Mode, auto mixing)
Turnigy 9x, PPM-Encoder
Pixhawk with Firmware 3.0.0 / also tried out 3.0.1(Beta)
Without Pixhawk it works.
I tried out all the same like Hugues. 1=Steering, 3=Throttle or throttle=2 makes no difference. Arming is possible but the motors are not running. I can see at CH3in the stick movements but Ch3out is remaining always at around 1500. (my neutral trim setting). I have disabled for testing all checks incl. the safty switch. Skid steering is disabled because of the mixed signal from the controller. But I tried out to set in/out to on/off on/on off/on. The controller should beep 3 times if it gets a RC signal. I think that is the problem - no RC signal from the Pixhawk even after arming it. But why? Cables checked and the optional setting for min pwm when disarmed is aktive. A test with Graupner Mz24 and sum signal makes no difference. No idea what to do next.
Any ideas? Hope somebody can help. Thanks, Tom
