Arrow keys to move, space to stabilize rotor speed automatically tries to keep you up (even even upside down) e to toggle engine don't land too hard (due to some glitch in my code that is nice 'cuz you cant land a real helicopter too hard) and land on your skis
I used @Will_Wam's smooth turning for stabilizing (but not manual turning) the rest is by me It took me AGES to find the exact numbers in the If <not <key up arrow pressed> or < Key down arrow pressed>>(these keys are for the stabilization of rotor speed) (they still aren't exact, the YV is off by something like 0.0003)
