Heli's - ===

[Major]

when you first takeoff in a heli, go into 'crashable' mode and off the engine. You will find that you crash! I mean, ifyou don't off the engine what other way is there to land?

[shinichiro nishiya]

In case of a 3D type heli, you should set the throttle stick at the center position when you start to fly.
Putting the stick down means move the heli downward and then crash into the ground.
