Since V2.00, the default Home position silently changed. This was not mentioned in the release notes, but is properly described in the latest user manual: Old: Home is where you first started the motors. New: Home is where GPS position has been determined for the first time. I noticed when I powered on under a tree and talked to someone. Then carried P2V to the open field and started the motors after seeing good GPS reception. After switching off the controller during flight, the P2V attempted to land in the tree instead of the open field. My fault, but apparently behavior can change unnoticed... Hope this was helpful to anyone.
