❑ Install the control horn and backplate, using two M2 x 14mm machine
screws, being careful not to overtighten them.
❑ Thread one nylon clevis onto the pushrod wire and snap the clevis
into the outermost hole in the control horn.
☞
Hold the pushrod wire with a pair of pliers to prevent it from turning
or twisting when installing the clevis.
❑ 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 aileron pushrod assembly onto the other half of the wing.

✦ You will need to plug a Y-Harness into the two aileron servo extension leads at this time. This will allow both
aileron servos to be plugged into the aileron channel in your receiver.
