SHIFT UP TIMING ADJUSTMENT
1. Once the engine adjustments have been completed, proceed to the
adjustment of the clutch shoe shift timing.
(Using a 2mm allen wrench to adjust the clutch shoe on either side.)
Note: Clockwise--------Shift timing will become later.
Counterclockwise---Shift timing will become quicker.
2. Adjust the clutch shift timing for your track conditions.
As you tighten (Clockwise) the 3x15mm screw, the shift timing will
become slower.
As you loosen (Counterclockwise ) the 3x15mm screw, the shift timing
will become quicker.
3. Set the shift timing to the track conditions while the car is running.
2 SPEED GEAR RATION COMBINATIONS
2 speed transmission allows the car to have more punch out of the
corners and higher top speed. We offer many different pinion and
spur gear combinations which can be used for different tracks.

Wrench
Use a 2.5mm allen wrench to adjust toe-in for front and rear.
Adjust the length of the front steering rod to change the toe angle.
(Front)
Making the steering rod longer will make the front tires become
toe-in.
Response will be slower and will over steer.
Making the steering rod shorter will make the front tires become
toe-out.
Response will be quicker and will under steer.
We recommended adjusting the front toe-out to 1.5 degrees.
(Rear)
Adjust the length of the rear hub (12mm ball/rear) to change
the toe angle.
Making the 12mm ball longer will make the rear tires toe-in.
Response will be under steer.
Making the 12mm ball shorter will make the rear tires toe-out.
Response will be over steer.
We recommended adjusting the rear toe-in to 2 degrees.
FRONT AND REAR CAMBER ANGLE SETTING
Note: Place the model car on a flat surface. Raise the chassis to it's maximum clearance
before the wheels leave the ground.
Adjust the length of the front and rear upper arms so that the wheels are right angles to the
ground.

The front camber adjustment can be made by moving the 14mm
steering ball at the front upper arms on knuckles, clockwise or
anticlockwise.
We suggest using 1.5 degress of negative camber for the front.
