Well, that didn't do the job either, although it's a move in the right direction.
The chopper does turn now; well half-ways anyway, but I can put the Game Logic wherever I want it still doesn't turn in the direction I want it to, I keeps turning half-way to the left and then stops!
Damn, why didn't they include a command like checkAzimuthonlanding, or determineAzimuthforlanding?
