•Set the transmitter power switch to ON, then set the receiver power switch to ON. The servos stop near the neutral
position. Operate the transmitter sticks and check if each servo faithfully follows operation of the sticks.

• Connect the pushrod to each servo horn, then check if the direction of travel of each servo matches the transmitter

• Operate each servo over its full travel and check if the pushrod binds or is too loose. Applying unreasonable force to
the servo horn will adversely affect the servo and quickly drain the battery. Be especially careful when using 8.4V.
•Always make the full stroke (including trim) of the servo horns somewhat larger than the full travel. Adjust the
servo horns so that they move smoothly even when the trim lever and stick are operated simultaneously in the same
direction.
• Be alert for noise.
Always solder a noise killing capacitor to the running motor. If metal parts touch each other due to vibration, noise
will be generated and cause the receiver servos to operate erroneously. We recommend the use of noiseless parts.
• Even though the receiver antenna wire is long, do not cut or bundle it. The range of the radiowaves will be shortened.

• Install the servos firmly. Install
the servo to the servo tray as
shown in the figure. In other
cases, install the servo as des-
cribed in the model manufac-
turer's manual.

• A spare horn is provided. Use it as required.
•Wrap the receiver in sponge rubber and wrap rubber bands around the sponge rubber. Mount the receiver so it is
not exposed to vibration, does not touch the frame, and does not move.
•When the receiver is installed on a board or used where it may be splashed with mud and water, place it in a plastic
bag, etc. and wrap a rubber band around the open end of the bag to waterproof and dustproof the receiver. After use,
remove the receiver from the bag to prevent condensation.
• Use the rubber bands wrapped around the receiver to hold the servo and switch leads.
•After mounting is complete, recheck each part, then check the transmitting range by making the transmitter antenna
as short as possible and extending the receiver antenna fully and operating the set from a distance of 20m to 30m. The
movement of each servo should follow the movement of the transmitter sticks.
• The crystal can be changed from the outside of the receiver case. (Except 72/75MHz in U.S.A) Always use a Futaba
transmitter and receiver crystal pair as the replacement crystals.
