I am looking at using an APM2.5 i have spare from an old quadcopter to put into one of my planes.
I am looking at only using the stabilize flight mode, and use the apm as just a really good stabilizer - as my current orangerx stabilizer just stabilizes big sudden movements and doesn't return the plane to level (like the APM will?).
Do i need to have the GPS module connected for the stabilize mode to work? I am not sure if my gps module has an external compass or not. Does the stabilize mode use GPS/compass or is it all the internal gyros? If so, i guess i will just disable the GPS somehow in mission planner?
Thanks for any info!
