APM 2.5, ArduCopter V3.1-rc5
Violent oscillations on take off.
My previous flights in Stabilize and Loiter had been fine. The only changes in this flight are that the hdop went from 1.3 to 1.96 in the space of about an hour, and that I flew in Stabilize-SuperSimple.
I did have the power on for a few minutes, playing around with changing modes and seeing what the high hdop would do. I wasn’t able to get the props to spin above the arm speed if I tried a Loiter take off because of the high hdop, so I went to Stabilize-SuperSimple.
Questions:
Does the APM reinitialize on arm, or can pre-arm values build up to cause the oscillations I saw?
Does SuperSimple need the GPS?
Attached are the data flash log and MP logs.
TIA,
Rick
