The function of the slipper clutch is to
protect the gearbox, differential and motor from shocks and also
to allow you to tune how the torque from the motor 'comes-in' when
you accelerate to suit different surface conditions. To adjust the
slipper clutch do the following:
Ensure model is switched off and drive battery is
removed then remove rear-right wheel with 7mm nut
driver or crosswrench.
Remove spur gear cover with 2mm hex driver. Hold spur gear with fingers. Use a 5.5mm nut
driver or crosswrench to loosen or tighten
slipper nut a 1/4 of a turn at a time. Refit spur
gear cover and rear-right wheel.
Slipper Clutch Adjustment
WARNING: A loose slipper will damage the friction pads. If
the slipper is too tight it may damage the transmission.
AFTER RUNNING:
If slipper clutch is too loose, tighten 1/4 turn.

the gears are still correctly meshed to prevent damage to the spur
