I'm not sure of the correct terms.

for example:
If I want the control surface to go up 3/8" and down 1/4" where to I make this adjustment?
Is this called differential? Do you have to do it with the TX or can it be done with control linkages?

Am I correct that the control horn should always be mounted with the holes lined up exactly above the hinge point?

Connecting to the control arm on the servo, the farther away from the servo gives me more movement.
When I attach the control arm to the servo, I just want to make sure the linkage does not bind when maxed out.


I'm using a spectum DX6i TX

TIA
