ADJUSTING YOUR MODEL
Motor
Screws
Strip of
Paper
Adjusting Gear Mesh
Incorrect gear mesh is the most common
cause of stripped spur gears. To set the
gear mesh, cut a narrow strip of notebook
paper and run it into the gear mesh.
Loosen the motor screws and slide the
motor and pinion gear into the spur gear.
Retighten the motor screws and then
remove the strip of paper. You should be
able to run a fresh strip of paper through
the gears without binding them.
Centering Your Servo
If the trim controls on your transmitter seem off, you may need to
re-center your servo. Additionally, whenever your servo has been
removed for service or cleaning, it must be re-centered prior to
installation in the model.
1. Disconnect the servo horn from the steering servo.
2. Connect the steering servo to channel 1 on the receiver. Connect
the electronic speed control (ESC) to channel 2.
3. Place fresh “AA” batteries in the transmitter and turn the
transmitter power switch on.
4. Turn the steering trim adjustment on the transmitter to the center
“0” position.
5. Elevate the rear wheels of the model. Connect a fresh 7.2V battery
pack to the speed control and turn on the ESC (see page 18). The
servo will automatically jump to its center position.
6. Turn off the power to the model followed by the transmitter. The
servo horn is now ready to be installed.
7. Be careful not to move the servo shaft when installing the servo
horn. Readjust the ESC as described in the “Adjusting the Speed
Control” section.
