Hi Jim
While mapping the collective to the throttle would work. It is a bit like mapping a variable pitch prop to a throttle.In most helo's I worked on the throttle was opened wide and then the collective was pulled on.
On most modern helos the engine is controlled fully automatically, so that you control only the pitch. But in some future I (or someone else?) will add realistic engine simulation to the "rotor", than you can control it by hand...
It is very interesting to see the look on the passengers faces when the pilot has not applied full power and the helo gets out of ground effect.As the rotor starts to take the full weight of the A/C the rotor speed drops and the helo settles gently back to earth.
As the helo has no control surfaces the direction has to be determined by differential lift on the main rotor blades. To go forward the rear going rotor blade has to provide more lift then the forward going rotor blade.And to go left the right going blade supplies more lift then the left going blade.So to work the Cyclic would require a cross calculation of the position of the aileron prop and the elevator prop at any given time.
It is simulated exactly like this.
The tail rotor could be tied to the rudder but it should give equal rotation around its axis regardless of the forward speed or lack of it of the helo.
Hm. I hink this is only correct for acrobatic (3D) model-helos with a (so called) heading lock gyro, but not for real helicopters (maybe the eurocopter tiger acts like this, not sure) (correct me, if I am wrong).
Hope this helps and makes sence

All the best, Maik
