4. Use a hobby torch to heat both the clevis and the
pushrod. Apply silver solder to the joint. The heat of the clevis
and the pushrod should melt the solder, not the direct fl ame
of the torch.
❏ ❏
5. While the joint is still hot but after the solder solidifi es
use a clean, damp cloth to wipe the fl ux from the joint before
it hardens. Flux is corrosive and must be thoroughly cleaned
from the joint.
❏ ❏
6. Coat the joint with a thin fi lm of oil to prevent corrosion.

7. Fit a silicone retainer onto the rod, a 4-40 hex nut,
another silicone retainer, and a 4-40 threaded clevis onto the
rod in that order. The threaded end of your pushrod should
look like the picture above.
❏
8. Repeat steps 2 through 7 for the remaining pushrods.

1. Use your radio to center your aileron servos. Attach a
1-1/2" [38mm] single-sided servo arm (GPMM1105) to each
servo so that the arm is parallel with the hinge line when the
servo is centered. Install the arms so that they point outward
toward the wing tip.
❏ ❏
2. Attach the soldered clevis end of each pushrod to
the servo arm in the hole that is 1-1/4" [32mm] out from the
center of the arm. Extend the pushrod straight back so that it
is 90° to the hinge line and draw a centerline on the aileron.
Use a builder's triangle to ensure that the rod is 90° to the
hinge line.
