Just setup a new quad copter with the APM 2.5 and firmware 2.7.3. Have done the initial PID tuning and the copter flies stably and well in Stabilized mode. Flight characteristics are very good. Self leveling is working well.
Flight mode 1 is "stabilized". Switch 7 is set to enable disable Simple Mode. However when we enable Simple Mode the aileron and elevator reverse stick control actions. The copter is still self leveling correctly so correction inputs are still being handled correctly but not stick inputs.
Would appreciate any input as how to resolve.
