Good Afternoon Team. I've tied to look this up but I seem to be spinning my wheels . I am seeking answers regarding compass location and how it effects the aircrafts performance . First question - Does it matter which leg it's mounted on and which direction should it be facing ? Secondly - Machine appears to want to RTH past 153 meters? Battery was at 53% and unit was on GPS mode. RTH point was about 100ft behind me...little bugger RTH at Mach speed and almost landed on a rock...flying hand save Thanks in advance. Dave.
