Hello,My new board has arrived (thank you Chris) and is working fine. I am an FPV flyer at the first place and automatic RTL mode is so tempting for me... Arduilot doesnt want to cooperate with my Corona RP8D1 in case of loosing RC signal. I added two little friends to the wire mess inside my small FPV platform.This is one of them:
First one is added between IN CTRL of ArduPilot and RC Rx. Second one between CPD4 RMT and Rx. This way I am not afraid of loosing the airplane during long runs.I think most of todays RC transmitters would benefit from such setup.
