To check the slip of the front differential, grab the RIGHT front wheel and hold the
spur gear. Turn the left front wheel. You should be able to turn the wheel but with
resistance.
To check the slip of the rear differential, grab the RIGHT rear wheel and hold the
spur gear. Turn the left rear wheel. You should be able to turn the wheel but with
resistance.

DRIVING THE MICRO TRUCK
After you have familiarized yourself with the controls and broken in the ball differentials, it’s time to drive your micro truck and have some fun!
Here are some things to keep in mind when driving your micro truck:
• DO NOT run the truck in or through water, snow, or mud. Even small amounts of water can cause electronics failure and loss of control.
• Avoid excessive high-speed operation running for long periods of time or long distances.
• Do not drive the truck with any kind of damage, especially drivetrain damage. This may cause motor damage from overloads due to drivetrain drag or friction, or over-
revving due to loose or missing parts.
• Do not use your truck to tow anything behind it; towing puts a high load on the motor.
• If your truck gets stuck, stop immediately! Move the truck and then continue driving.
• NEVER turn off the radio system while the truck is on, as this could cause the truck to go out of control.
ADJUSTING THE MICRO TRUCK
GEARING
FRONT TOE
Adjust front toe by adjusting the length of the left and right steering rods.
Steering rod length
Characteristics
More front toe-in =
longer steering rod
· increases straight-line stability
· decreases steering response
· increases steering mid-corner and on-power corner exit
More front toe-out =
shorter steering rod
· decreases straight-line stability
· increases initial steering response
· decreases steering on-power at corner exit
To change pinion gears, first remove your motor along with the old pinion gear. Install the new pinion gear and re-install your motor. When installing the two 2x8mm button head
screws to secure the motor mount to the chassis, do not fully tighten them. Leave them just loose enough so you can slide the motor in and out towards the spur gear. Make sure
there is sufficient space between spur gear and pinion to allow for a small amount of backlash so the gears do not bind, see the diagram. When you have the motor in this position,
you may then fully tighten the motor mount screws. Always check the gear mesh one more time to confirm that the motor did not move when tightening the screws.
