machine screw and #1 Phillips screwdriver to secure the
interplane strut. The right and left upper wing panels are

10. Thread a clevis on each end of a 3mm x 270mm
threaded rod. Connect the rod between the top and bottom
ailerons. With the radio system on and the bottom aileron
centered, adjust the length to center the top aileron. Once
centered, slide the silicone tubing over the forks of the clevis
to prevent it from opening accidentally. Apply threadlock on
the nuts and clevises to prevent them from vibrating loose.
Use needle nose pliers to tighten the nut against the clevis to
prevent it from vibrating and changing positions.
