threads in the four mounting holes. Attach the engine
to the mount using four 8-32 x 1" [25mm] SHCS, four
#8 fl at washers, and four #8 lock washers.

6. Glue the throttle servo tray in the location
shown. Be sure that the cutout for the throttle servo is
on the same side of the plane as the throttle arm on
the carburetor.
❏
7. Cut three arms from a four-armed servo arm.
Install a brass screw-lock pushrod connector into the
second hole from the center of the remaining arm
using a nylon retainer. Loosely thread a 4-40 x 1/8"
[3mm] SHCS into the screw-lock pushrod connector.
Install the throttle servo into the throttle servo tray with
the servo splines toward the rear of the plane. Use
your radio system to center the servo and attach the
arm perpendicular to the servo case pointing away
from the center of the fuselage. Be sure to install the
servo arm screw.
❏
8. Make the necessary bends in the remaining
36" [914mm] pushrod so that it will connect to the
throttle arm on your carburetor using a nylon clevis
and silicone clevis retainer. If installing the O.S. FS-
91 Surpass II four-stroke engine, a “U” bend will
need to be made in the pushrod to reach the throttle
arm. Be sure that the bends you make are not in the
threaded portion of the rod. Some of the threads on
the pushrod can be cut off to get the clevis closer to
the “U” bend. Fit the aft end of the pushrod through
the screw-lock pushrod connector in the throttle
servo arm. Make any necessary adjustments to the
pushrod position and tighten the screw in the screw-
lock pushrod connector when satisfi ed. Cut off the
excess pushrod 1/4" [6mm] beyond the screw-lock
pushrod connector.
❏
9. Test the operation of the throttle servo with your
radio system, making sure that the servo can properly
open and close the carburetor.
INSTALL THE RECEIVER & BATTERY
❏
1. Glue the fuel tank brace to the receiver tray in
the direction shown.
❏
2. Make two hook and loop straps by overlapping
the mating ends by approximately 1" [25mm]. Cut
two pieces of foam rubber (not included) to match
your receiver and receiver battery pack. Secure the
receiver and receiver pack to the receiver tray with
the straps and cut them to the necessary length.
Feed the antenna and battery lead beneath the air
tank tray and secure the radio tray to the fuselage
