Adjusting the Slipper Clutch
Your Traxxas model may be equipped with an adjustable slipper clutch which is built into the large spur gear. The purpose of the slipper clutch is to regulate the amount of power sent to the rear wheels to prevent tire spin. When it slips, the slipper clutch makes a high-pitch, whining noise. Remove the rubber slipper clutch plug on the transmission cover in order to adjust the slipper. Use the 4-way wrench to turn the adjusting nut clockwise to tighten and counter-clockwise to loosen. Place the model on a high traction surface, such as carpet. Adjust the slipper so that you can hear it slip for approximately two feet from a standing, full throttle start.

To achieve a good starting point for the slipper clutch in these models, tighten the slipper clutch adjusting nut clockwise until the slipper clutch adjusting spring fully collapses (do not over tighten), and then turn the slipper clutch nut counterclockwise one full turn.
Do not run your model with the slipper clutch adjusting spring fully compressed. The minimum recommended slipper clutch setting is 1/2 turn counter-clockwise from fully compressed.

The slipper clutch is adjusted by loosening the spring-loaded locknut on the
slipper shaft. Use the supplied 8mm open-end metric wrench. To tighten or
loosen the
slipper nut, insert the 2.0mm hex wrench into the hole in the end of the
slipper shaft. This locks the shaft for adjustments. Turn the adjustment nut
clockwise to tighten (less slippage) and counter-clockwise to loosen (more
slippage).
From the factory the slipper clutch is set for minimal slippage, just enough to
protect the drivetrain from shock loads. On slippery, low traction surfaces
such as a hard-packed, dry racetrack you may benefit from loosening the slipper
adjustment nut to allow for more clutch slippage. This will make the truck
easier and more forgiving to drive by helping to reduce the amount of wheel
spin. Loosening the slipper adjustment can also improve performance on extreme
high traction
surfaces by preventing the front end from lifting off of the ground when
accelerating. Make slipper adjustments in small 1/8 turn increments.
The maximum tight setting for the slipper is just at the point where there is
little or no tire slippage on a high traction surface such as carpet or a
prepared racetrack. The slipper should not be tightened to the point that
clutch slippage is completely eliminated. Do not overtighten the slipper nut or
you could damage the slipper bearings, pressure plates, or other
components.
