We've got a couple 2.5 APMs in use they are pretty fun to use. I tried one in a delta wing today but during my ground check I found that after I power up the system and it's ready to fly about 20-30 seconds after that I no longer have manual control of the aircraft even though I'm in manual mode. The aircraft surfaces move as if the autopilot is trying to move them but I have no input. If I switch to Stabilize I instantly have control back and the Stabilize function seems to be working.
Failsafes in the Ardupilot are disabled. JR radio with spectrum receiver and if I remove the autopilot the RC equipment works fine and I'm not showing any receiver hits at the time I lose control.
I tried a full reset at the CLI and reloaded and calibrated the system again but got the same results. After 20-30 seconds surfaces don't respond. They don't come back, switchting to Stabilize get's me control back, then I can return to manual mode.
I'm puzzled hope you guys can help.
Configuration info: APM 2.5 all-in-one with external GPS Arduplane Firmware 2.68.
