4. Position the control horn onto the aileron. Match
the fore-aft position of the horn to the one pre-
installed. The pushrod wire will be parallel to the
wing ribs. Mark the location for the screws using
a felt-tipped pen.
5. Use a 5/32" (2mm) drill to drill the two holes
for the control horn mounting screws. Use the
backplate and two 2mm x 12mm screws to attach
the control horn to the aileron.
