RE: Tiger Stick 40 Rolling Too Slow
On the contrary, Dennis. Moving the clevis farther away from the center of the servo and moving it closer to the hinge line on a control surface will put the same amount of "stress" on a servo.
But if you move it closer to the hinge line at the control surface, you lose mechanical advantage. You may find that even though you have more surface throw, you have less control authority, since the force on the surface by external factors (moving air, etc) keeps them from moving as far as you want.
By using longer servo arms, you gain mechanical advantage and the extra control surface movement.
On a trainer or sport plane, 40 to 60 size, you will be hard pressed to ever "stress" a standard servo.
