Step 11
Remove the pushrod wire from the fuselage and remove
the clevis. Bend the pushrod wire at the mark. Slide
the pushrod back into the fuselage from the radio
compartment, and then put the clevis back onto the
wire. Use a pushrod wire keeper to secure the pushrod
wire to the servo arm.
Step 12
Check the movement of the throttle to verify there is no
binding at either low or high throttle. If there is, make the
necessary adjustment to eliminate any binding. Install the
throttle servo arm screw when complete.

", from one
end. The holes must be parallel to each other.
Step 14
Cut a groove into the pushrod from the hole to the end
of the pushrod. Repeat for the opposite side so you end
up with two grooves. The elevator pushrod wires will
rest in these grooves.
Step 15
Locate the two 7

" pushrod wires. Make a bend in one
wire 1/4" from the non-threaded end of one of the wires.
The remaining pushrod is bent 1/2" from the end.
Step 16
Test fit the two wires. The wire bent at 1/2" is placed in
the hole closest to the pushrod end. You will have to
trim the wire down after the bend so it won’t interfere
with the other pushrod. Once fit, use medium CA to
glue the wires to the dowel.
