Default RE: GPS guidance

I have been working a little one and it is progressing very well....

Here is some "log-book" videos taken during this last week of testing...

Video of a hand launch with AP enabled (radio off). The aircraft took off, and completed a 2 waypoint route on auto pilot control.

Video of a return to home scenario. Only one waypoint programmed.
Just after the video cuts, the hovering plane starts flying backwards (big headwind) and fouls gps nav info and I choose to take control..
I am using a garmin 301 with the elec compass turned off... In the set-up of the garmin elec compass, you can set at what speed the gps compass takes over. If would have used the elec compass (set for up to 7mph), when the plane came to a hover, the elec compass would have kept the directional data correct. ( I think ) Need to test that...

Video of easystar completeing the 7 waypoint route and circling the last waypoint attempting to maintain 200' altitude.. It circled the last waypoint for about 3 minutes and drifted down to within 50' AGL. I need to turn up the throttle gain..

EDIT: In my eariler post I said it was PCM failsafe, it is not. The AP activtes upon loss of control channel.
