Ah yes, I remember the problem. I think all you can do is set the the waypoint to 'takeoff'. Somehow the mod seems to have a 'retractable undercarriage'! hock:

And by the way, be careful going too fast, it can do odd things. And don't drive into tight corners, you've got no reverse gear. Remember, this mod is just a bit of fun, don't expect too much from it.
