2. Unravel the receiver antenna and plug the servo and batte ry con nectors into the
receiver.
3. Extend the transmitter antenna.
4. Turn On the power switch of the Transmitter.
5. Turn On the power switch of the receiver.
6. Set the small trim levers to the center position and make sure that bo th main control
sticks are also centered.
7. Move both main control sticks slowl y through their full tr avel. The serv o horns should
move in proportion to the movement of yo ur sticks.
8. When trim levers and sticks are at their neutral positions, the ser vo horn s should
be centered. You may now turn off the transmitter, then the re ceiver and unp lug the
servos and batter y from the receiver.

A 2-channel radio control sy stem is composed of a transmitter, recei ver, two servo s and
a battery holder (for the receiver).
*Transmitter •.... This is the part of the system that y ou hold in your han ds to control
the model. Information is sent to the receiver and servos v ia radios
waves.
*Receiver .......• Receives the radio signals from the transmitter and send s them to the
appropriate servo.
*Servos ..•.•..... It can be thought of as the "muscle" of the syst em. Th ey actually move
the controls of the model. The receiver tells them wh ich direction to
move and how much.
*Antenna ......... The transmitter antenna broadcasts the radio si gnal .
The
receiver antenna (which is no more than a s mall w ire tuned to a
precise length) picks up the signals so that the rec eiver can decode
them.
*Trim Levers ..•.. Adjust the neutral position of the servos from the transmitter.
Trim levers prov1de fine tuning of the steerin g c:lltG s peed control.
*Battery Meter ... Allows you to see the condition of your transm it t er batteries.

as sem bl y w ill enabl e y ou to build the kit without difficulty. Check the components in the
ki t prior to your startings the assembly. Any claims for replacements or refunds for the
model in the pro c ess of assembly will not be accepted.
(Please un derstand the folowing points before assembl y)
1. Learn th e Marks described in the Instruction
Points where grease should be applied.
(It will reduce friction and assure smooth movement. )
Places to put some locktite.
(It will prevent the screws and nuts get loosen by vibration while running.)
Steps where y our particular attention is required.
2. Small Parts
The small parts to be used such as screws, nuts, washers are illustrated in the actual
size on the attached sheet "The List of Small Parts" . Pick up the correct ones referring
the size, shape, and the assembl y number.
3. Some Hints when screwing in a self-tapping-screw, (hereinafter referred to as TP Screw).
This model uses a lot of plastic parts. And many TP Scews will be used for assembling.
Do not use ex cessive force when tightening the self-tapping screws, or you may strip
the thread in the plastic. It is recommended to stop tightening it when the threaded
part on the screw goes into the plastic part and y ou feel some resistance from the
tightening.
4. Shape of Screw
Y ou can distinguish the ordinary screw form the self-tapping one by the shape of points
and thread.
