the servo tray as shown. Use thin or medium CA to glue the
pushrod tubes to the brace and the fuselage where they exit.
Let’s hook up the throttle...
❏
17. Cut a 12" [300mm] pushrod tube from any remaining
3/16" [4.8mm] gray pushrod tubing. Roughen one end of the
tube with coarse sandpaper so glue will adhere. Guide the
pushrod tube through the hole in the firewall and through the
fuselage until 1/8" [3mm] of the roughened end protrudes from
the firewall.
❏
18. Fit a screw-lock pushrod connector in the second from
the center hole of the throttle servo arm. Secure the screw-lock
pushrod connector with a nylon retainer.
❏
19. Thread a nylon clevis onto the end of the 18" [460mm]
pushrod. Slide the pushrod into the tube, then bend the
pushrod as necessary and connect the clevis to the top hole in
the carburetor arm. Fit the other end of the pushrod into the
screw-lock pushrod connector on the throttle servo.
❏
20. Use thin or medium CA to glue the throttle pushrod tube
in the firewall.
Now the servos are hooked up, but final adjustments have
to be made before the model will be ready to fly. First, the
antenna and on/off switch must be mounted.
Hook Up the Controls
❏
1. Mount the on/off switch in the precut opening on the left
side of the fuselage (opposite the engine exhaust). Be certain
the opening is large enough to allow the switch to fully turn on
and off. If necessary, enlarge the opening.
❏
2. Connect the switch to the receiver and battery already
mounted in the fuselage.
❏
3. Cut a piece of leftover 3/16" [4.8mm] gray pushrod tube
to a length of 4" [100mm]. Roughen the tube so glue will
adhere, then glue the tube to the inside of the fuselage as
shown. Guide the receiver antenna in and out the holes in one
of the servo arms you saved from earlier. Route the receiver
antenna through the tube. Drill a 3/32" [2.4mm] hole through
the top of the fuselage as shown, then guide the antenna out
of the hole.
❏
4. Make a “hook” as shown in the photo from the other cut
off servo arm you saved. Connect the antenna to a pin stuck in
the fin via the hook and a small rubber band. Do not cut off the
rest of the antenna, but let it trail from the hook.
❏
5. Connect a 6" servo extension wire into the aileron
receptacle in the receiver (labeled “1” in most receivers).
Connect the on/off switch and the three servos in the fuselage
to the receiver as well (in most receivers, the elevator servo
should connect to receptacle 2, the throttle servo should
connect to receptacle 3, and the rudder servo should connect
to receptacle 4). Be certain none of the servo wires interfere
with the pushrods.
Now the plane is assembled, but there are a few things that
must be done before it will be ready to fly. You must carefully
perform all of the following setup procedures. If possible,
have your flight instructor assist.
