7. Install a brass screw-lock pushrod connector on the throttle
servo arm. Secure it with a nylon keeper. Thread a 4-40 x 1/4"
[6.4mm] socket head cap screw in the pushrod connector.
❏
8. Drill a 3/16" [4.8mm] hole through the forward former,
inline with the throttle arm. Insert the 3/16" x 24" [4.8mm x
610mm] gray outer pushrod in the hole and route it through
the fuel tank bay. If needed, drill a 3/16" [4.8mm] hole in the
former at the front of the wing saddle to allow the outer
pushrod to align with the throttle servo. Use sandpaper to
roughen the pushrod tube before gluing it to the formers.
❏
9. Thread a nylon clevis 14 turns onto the 2-56 x 17"
[432mm] metal pushrod. Slide a silicone clevis retainer over
the clevis. Insert the pushrod in the outer pushrod tube and
through the pushrod connector on the throttle servo. Attach
the clevis to the throttle arm on the carburetor.
❏
10. Switch on your transmitter and connect the throttle
servo and receiver battery to the receiver. Adjust the throttle
pushrod so that the throttle opens and closes correctly. Tighten
the 4-40 socket head cap screw, in the pushrod connector,
against the throttle pushrod and cut off the excess pushrod.

1. Use sandpaper to roughen the backside of the two holes
for the machine guns and the mounting rings on the machine
guns. Clean the area with denatured alcohol.
