Here are some of my Helicopter and Quadrocopters. I try to get a good weight balance, so if you press nothing it should hold the position in air

To move in a direction you need to tilt the vehicle to the direction and it will move automaticly.

General Controls:
Up: nose down (y axis)
Down: nose up
Left: rotate left (x axis)
Right: rotate Right
y: rotate left (z axis)
x: rotate right
left shift: increase altitude
left ctrl: decrease altitude

Helicopter with a Bomb, press c to drop. The top Balloons will be droped too, to balance the weight

Same but without bomb and balance balloons

Smaller, not so stable Quadrocopter

Most recent idea, replace controling units from flying blocks to actual propellers. increased manourverbility. especially eliminated the problem of slow raising/sinking of previous copters. a different control. this ones front is rotated by 90 degree. use up,down,left,right to increase altitude.

Have fun and give me some ideas or improvements^^
