Experimental Flying wing 1.1

I did some jbeam reworking, it is better now, but there is still room for improvement of course. Also there is now more power and thrust vectoring.

Max allowed speed is 80kph, use airspeed UI app, because above that steering is not possible!

Min speed is 50kph, it does fly even 30kph but steering at such speed will cause stalling very easily.

Map T-function to gamepad button and use that to speed up, JATO is just replacement of cruise control for level flight, but I might remove that in future as it is pretty useless.
