5. Make a 90º bend in the pushrod on your mark, then

insert it through the enlarged hole in the servo arm. Secure

the wire in place with a nylon FasLink. Trim the excess wire

1/16" [1.5mm] above the FasLink.

6. Install the elevator control horn by positioning the horn

as close to the inboard edge of the elevator as possible and

mark the location of the mounting hole. Drill 3/32" [2.5mm]

mounting holes through the marks. Wick two to three drops

of thin CA into the holes to harden the underlying balsa, then

re-drill the holes. Attach the horns using two 2-56 x 5/8"

machine screws and a nylon nut plate. Do not overtighten

the screws, crushing the underlying balsa.

7. Install the elevator pushrod. Place a clevis retainer onto

the clevis. Thread the clevis 14-turns onto the pushrod.
Attach the clevis to the outer hole of the control horn.
Slightly bend the pushrod wire as necessary to allow for free
movement.

8. Center the elevator and elevator servo and mark the

pushrod where it crosses the servo arm. Enlarge the servo

horn hole with a 5/64" [2mm] drill bit.

9. Make a 90º bend in the pushrod on your mark, then

insert it through the enlarged hole in the servo arm. Secure
the wire in place with a nylon FasLink. Trim the excess wire
1/16" [1.6mm] above the FasLink.

10. Install a brass screw-lock pushrod connector with the

4-40 x 1/8" cap screw on the throttle servo horn. Snap the

nylon retainer onto the screw-lock pushrod connector post

beneath the servo horn.
