Actually, it's the other way around. By adding two additional servos to independently control the elevator, you are decreasing the amount of control surface This makes the plane less pitch sensitive. With only two servos, all four control surfaces were being used to control pitch. With four servos, only two control surfaces are being used. The plane will still be very maneuverable, but not so sensitive that it is unmanageable in flight. I hope this is correct. Opjose will correct me if I'm wrong.
Correct, particularly since you can then independantly adjust the "throws" ( the movement AMOUNT ) for the ailerons and elevators... something you cannot do with only two servos.
You want LESS movement of the elevator than the ailerons.
Bobmaster what planes have you flown before?
