7. Maintenance
Checking the tooth flank play
The model is already assembled ready to run
and can be put into operation immediately.
For optimum transfer of force, however, occa-
sionally the tooth flank play between the motor
pinion and the main gear wheel should be
checked.
Only if the gear wheels turn smoothly and
mesh into one another without play will the
moderate power be used entyrely and prema-
ture wear prevented.
For this, the motor shaft and the drive shafts
to the front and rear axles have to be aligned
to be precisely parallel and the gap adjusted in
optimum fashion.
Insert a strip of paper between the motor
pinion and the main gear wheel and turn
by hand. If the strip of paper tears when drawn in, then the gap is too small. As a result, tension may develop
in the power train as well as premature wear of the bearings in the clutch and motor.
If the gap is too large, the motor pinion may slip. The result would be jerking in the drive and premature wear
of the gear wheels.
To correct the gap, loosen the motor retainer screw and shift the motor accordingly.
Restoring the transmitter/receiver link
The transmitter and receiver are already correctly preset at the factory and can be used immediately. Restoring the
link is necessary only after changing the receiver and transmitter or to rectify an error.
Carry out the following procedure to restore the link:
Switch off the transmitter.
For safety reasons, disconnect the servo cable from the receiver
Plug in the binding cable into the connection for Channel 3 (Bind) on the receiver.
Connect the receiver rechargeable battery to the receiver. The LED on the receiver starts blinking..
Press the bind button on the transmitter and hold it down, while you switch the transmitter on.
When the LED on the receiver stops blinking, the binding is completed.
When the LED on the receiver stops blinking, the binding is completed. This may take about 5 seconds.
Release the bind button on the transmitter and detach the binding cable from the receiver
Connect the servo / speed controller back to the receiver
Check the functioning of the servos and the range of the remote control system. (page 27)
If the servos do not react correctly, repeat this procedure
