RECEIVER AND SERVO CONNECTIONS
Your Blazer or Blazer Sport R/C system is equipped
with a BEC receiver to eliminate the need for a
separate battery receiver pack, but you can use a
separate power supply if desired for your particular
model. The following diagram shows a typical
connection for the servos and receiver.
Note that the receiver antenna should be located at
least 2” (50 mm) 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.
Be careful to avoid any metal parts coming in contact
with the servo connectors as this will affect the
performance. 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.
