ok thx. I'll give it a go

and can I also make a "landing" animation via ConditionState triggers when I switch from AirLocomotor to GroundLocomotor?
//EDIT:
Great!!! The locomotor switch works fine

*happy*
But one new problem is the animation now.
The ConditionState RIDER1 is the state when the unit is flying, RIDER2 is for the ground locomotor, the landing of the unit.
So, I included the animation tags and it works indeed... BUT only once

(the first time when it lands and then when it prepares to fly again).
I tried to have the LocomotorDummies died immediately after they appear but it also didn't work...
Any ideas how to get the animations always and not only once? :/
