Section 17: Aileron Control System Installation - Model Tech Magic Formula 3D ARF Manual

Use a piece of masking tape, taped between the rudder and the stabilizer, to hold the rudder centered.
Remove the masking tape from the rudder and double-check that the servo horn and the rudder are still centered. If the
rudder is not centered, adjust the clevises until it is. Move the rudder right and left several times to ensure that the linkage assembly
does not bind. It should operate smoothly in both directions.
Move the rudder control stick completely to one side. Let the control stick go and check to see if the rudder returns to center. Do
this a couple of times in each direction. If the rudder does not return to center consistently, adjust the tension of the pushrod wires
by adjusting the clevises. Ideally, the pushrod wires should be as tight as possible, while still allowing the rudder to return to center.
The pushrod wires should not have slack in them, yet they should not be so tight that the linkage and/or the servo bind.
