RE: 4 channel control
hahahahahahaha.
That was good.
Heh, Mode 1 is US standard. Mode 2 is rest of world.
It's just that Mode 2 is easier for Heli pilots since the right stick then becomes Cyclic.
The difference in Mode 1 and 2 is whether the collective is on the left or the right.
Rudder is always on the left. "Aileron" is always on the right.
"Elevator" is wherever Cyclic (throttle) isn't.
