Well, it is a bit hard to add without dictating how the model should be used. If you were to trigger the height change, the animation would only contain the airplane tilting backwards while still in the air, but that would look weird for people who want to use it as a normal unit, like the gyrocopter (although this is something i strongly disadvice). Overall it is problematic, since the birth animation is always played automatically when the model is spawned, so it could cause issues for people who want to use it in a flight simulator, or who doesn't want to add a lift-off sequence to it. Still, i appreciate all feedback!
