Section 18: Cowling Installation - Model Tech Magic Formula 3D ARF Manual

Remove the masking tape from the aileron and double-check that the servo horn and the aileron are still centered. If the aileron
is not centered, adjust the clevis until it is. Move the aileron up and down several times to ensure that the linkage assembly does
not bind. It should operate smoothly in both directions.
Repeat the previous procedures to install the second control horn and clevis assembly to the aileron on the other half of the wing.
IMPORTANT If you will be flying your Magic Formula 3D ARF using a non-computer radio system without mixing capabilities,
you will need to plug a Y-Harness into the two aileron servo leads at this time. This will allow both aileron servos to be plugged into
the aileron channel in your receiver.
If you will be flying your Magic Formula 3D ARF using a computer radio with mixing capabilities, you may want to plug each aileron
servo lead into your receiver separately (into Ch. 1 and Ch. 6) to take advantage of your radio's mixing capabilities.
