TRANSMITTER BATTERY INSTALLATION
RECEIVER AND SERVO CONNECTIONS
Your MX-3 Computer R/C system receiver is NOT
equipped with BEC circuitry. DO NOT use more
than 6.0 volts to power the receiver. Anything higher
than 6.0 volts will burn-up or destroy your receiver.
Only use a 4.8~6.0 volt battery pack or a speed
controller that is designed to lower the voltage to
the receiver. The following diagram shows a typical
connection for the servos and receiver.
Note that the receiver antenna should be located at
least 2” (50mm) away from any servo leads and
switches. In electric cars, we recommend that it be
at least 4” (100mm) from the electric motor.
Extend the receiver antenna to the full length. Failure
to do so will cause loss of control. Do not cut or bend the
receiver antenna.
Insulate the connectors with tape or use tie wraps to
avoid contact with metal car chassis.
Please follow the model manufactures recommendations
for the correct installation of your radio system in your
car or boat.
