Assembly Precautions

WARNING
 Check the receiver, servos, and battery connectors, to be sure they are firmly connected.
If a connector is not fully inserted, vibration may cause the connector to work loose while
the model is operating. This will result in loss of control.
 Operate each servo horn over its full stroke and check to see that the linkage does not bind
or is not too loose.
Excessive force applied to the servo horn by binding or poor installation may lead to servo
problems and result in loss of control.
 (Electric Cars and Boats)
Isolate the receiver from vibration by attaching to the chassis or mounting plate with thick
double sided tape.
(Gas Powered Cars and Boats)
Isolate the receiver from vibration by wrapping it in foam rubber or similar type cushioning
material. Protect the unit from water damage by placing it in a plastic bag or waterproof ra-
dio box.
The receiver contains precision electronic parts. These parts are vulnerable to vibration and
shock. Any contact with moisture (water or condensation) may cause receiver malfunction
and loss of control.
 Use the servo horn screw.
When the servo horn comes off, it becomes loss of control.
 Keep all devices that emit high frequency noise, such as motors, batteries, and wiring
that handles heavy current loads, at least 1/2 inch away from the receiver and the receiver
antenna.
High frequency noise will cause a decrease in operating range and could cause loss of
control.
 Install electronic speed control heat sinks as well as other components that conduct
electricity so they can not come in contact with aluminum, carbon fiber or other materials
that conduct electricity.
If, for example, the speed control came loose while the model was running and touched an
aluminum chassis, a short circuit may occur that would cause irreparable damage to the
system as well as loss of control.
 Noise suppression capacitors should be installed on almost all motors.
If the proper capacitors are not installed, high frequency noise will reduce range and cause
loss of control along with various other problems.
 Inspect all linkage installations and any point where metal could come in contact with other
metal parts. Make sure these parts do not touch other metal parts under vibration.
Should a linkage or other metal parts come in contact with other metal parts under vibra-
tion, the high frequency noise generated by this contact will cause interference and pos-
sible loss of control.

CAUTION
 Do Not disassemble any part of this system that is not specified in the instruction manual.
Futaba will not be responsible for any damage due to improper disassembly of any part of
the radio control system.
