Apologies for the delayed response but as you can see from this ( Copter rotate all axes when throttle is engaged ) topic this has already been tried and it didn’t work for me.
Another thing that makes me think that its something other that the RC is because it doesn’t even take off properly with the Ground Control Station. Another thing to note is that it worked perfectly with PX4 and I had a similar experience with my other home build for ArduPilot. The common denoninator seems to be ArduPilot.
Can a param file from PX4 be copied over to ArudPilot?
