Checking the tooth flank play
Das Modell ist fahrfertig aufgebaut und kann The model is already assembled ready to run and can be put into
operation immediately.
For optimum transfer of force, however, occasionally 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 premature 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 it 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/recei-
ver link
The transmitter and receiver are already cor-
rectly 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

Regular checks

Check:
The model and the transmitter for any visible damage
To be sure all the screw connections are tight; during operation, parts and screw connections may become
loosened through motor vibrations and shocks.
To be sure that all the turning/moving parts move smoothly;
Plug connections for contact and cables for secure installation
The snugness of the link lever and the servo arm on the servo shaft
The charging level of the transmitter and rechargeable drive batteries
The symmetric adjustment of the shock absorbers of one axle
The condition of the tyres
