it doesn;t happen when airborne, and to all You trolls, it is not whining. it is simple intel to help Hitech keep customers,
When you're airborne, the plane is flying, so the disco autopilot is able to keep it flying. When you're on the ground, the plane is not flying, but apparently the disco autopilot tries to keep it flying and in doing so rolls it across the field until it crashes into something.
If you posted this in the bug reports forum, in a proper bug report format (instead of your typical way that invites "trolls" to respond), it would be more helpful to HT and perhaps it would get the proper attention. Just put a little effort in your posts, so they don't all sound like whines from a 12-year-old.
