i have a Pixhack V3 and I use the px4 stack along with a µWave 12 Channel 2,4Ghz receiver from Schulze and the regular PPM SBus Encoder that comes with the pixhack.
My Problem is, that when I switch to manual mode, the servo hooked up to the rail of the pixhack is not responding at all. Although I can see the servo signal in qgroundcontrol when swithcing to "radio" an moving the sticks on my radio.
I am using the pixhack indoors, so no valid GPS an I have no airspeed sensor. The pixhack is blink blue light slowly - so it is not armed and ready to take off.
BUT: I expect, that If I am in manual mode, I should have full control over the servos - no matter what sensor is up an running (the GPS or Airspeed sensor could fail in flight aswell an the manual mode has still to work).
But nothing happens. Is there any hint about how to fix this ?
