9/16"
[15 mm]
AILERON Servo Arm
❏
4. Temporarily connect the aileron servo to the receiver
and turn the system on to center the servo. Fit a servo arm
to the servo that will have holes 9/16" [15mm] apart and cut
off the unused arms.
Torque
Rod Horn
Pushrod
Make sure the end of the pushrod is not
contacting the side of the torque rod horn.
NO YES
❏
5. Connect the servo arm to the torque rods with the
included pushrods. Center the ailerons and temporarily
tighten the screws in the screw-lock connectors to lock the
pushrods down. Make sure the ends of the pushrods do not
contact the sides of the torque rod horns. If they do, shorten
the pushrods as necessary.
❏
6. With the radio on and the ailerons centered, securely
lock the pushrods down to the screw-lock connectors with
the screws and a drop of threadlocker.
❏
7. Make sure the servo arm screw is in place. Turn on
your transmitter and lower the throttle stick. Install and
connect the motor battery, then connect the aileron servo
wire to the receiver. Mount the wing to the fuselage with
the included 3mm x 10mm counter-sink fl at-head Allen
screw. Operate the ailerons to make sure the servo arm,
pushrods and torque rods are not interfering with anything
else down inside the fuselage (such as the elevator servo,
receiver or wiring).
❏
8. Since you’re working on your ailerons and have them
operating now, this would be a good time to set the aileron
throw as noted on page 12 (or, you could wait to set the
throws when you get to that part of the manual later).
Mount the Landing Skids
Don’t fl y your Rifl e without the landing skids. In addition
to protecting the underside, the landing skids perform
the important function of causing the plane to maintain a
straight-ahead trajectory on landing. Otherwise, it may spin
and pirouette, causing one of the wing tips to dig into the
ground and possibly cause damage.
❏
1. Find an assistant to hold the wing as shown in the top
photo, with the trailing edge against your workbench. Use a
small builder’s square and a pencil to mark vertical lines on
the bottom of both wings 1-1/2" [40mm] from the tips.
❏
2. Apply strips of masking tape 1/16" [1.5mm] on both
sides of both lines.
