Bill Bonney replied to Mick's discussion APM 2.5 flyaway"Thanks for the info. As a FYI for others:
The compass feature is discussed here http://code.google.com/p/ardupilot-mega/wiki/RCSetup though there is no mention of the parameter, but it does fully cover the topic.
The parameter is mentioned…"
Mick replied to Mick's discussion APM 2.5 flyaway"Solved.
