Hello
I connected a Graupner GR12s with PPM at the PX4 (Pin 6 - Multi-Plug). But in QGroundControl is no signal from the sticks visible. Is it essential to activate PPM in the software?

Ok, I found the solution: SYS_Autostart: 4008, then it works
Hi, have you used the transmitter to tell the RX to sum its outputs? on the GR24 its SUMO 8 to sum all outputs on pin 8
HTH
Hi Colin
Thanks for your answer. Yes i set up the GR12s to SUMO16. The Sum output pin is 6.
