Mount the control horn to the aileron, directly behind the

pushrod wire, using two 2mm x 30mm machine screws.  Make
sure that the control horn is parallel to the hinge line and that
the clevis attachment holes are over the hinge line.

The centerline of the control horn should be approximately

7-1/4" out from the inside edge of the aileron.

Thread one clevis onto the pushrod wire and snap it into

the 

fourth hole

 out from the base of the control horn.

Repeat the previous steps to install the second aileron

pushrod assembly on the opposite wing panel.
