Please note on the subject! The response from some of you have not followed. I'm all for this idea. More over, I would like to clarify what would be the gateswould be really cool to do. The gate, which it self apart and they are external to the rigidmounts. More over, it would be possible to make their opening remotely.
So I want to draw your attention to another aspect. I like many players, lover of flying in helicopters, airplanes. Moreover, many love to do this thing in the expert mode. Your project for some reason does not support this feature. Maybe we should implement it?
