WHEELBASE ADJUSTMENT
The RC10GT wheelbase can be
changed easily to allow further fine tuning
of your truck for different track conditions.
This can be accomplished by moving the
1/8” (3.17mm) plastic spacer on the rear
outer hinge pin (next to the rear hub car-
rier). If the spacer is located in front of the
rear hub carrier, it will lengthen the wheel-
base and increase steering. If the spacer
is located in the rear of the rear hub carri-
ers (which is the stock position) it shortens
the wheelbase and give more rear traction.
CAMBER LINK ADJUSTMENT
Changing the mounting position of the
camber links can affect traction, stability,
and handling on rough tracks. Use the fol-
lowing guidelines to try and find the cor-
rect handling for your track conditions.
Using a longer mounting position will
increase traction but decrease stability and
rough track handling.
Using a shorter mounting position will
decrease traction but increase stability and
rough track handling.
RIDE HEIGHT
Now we check the ride height of your
RC10GT to make sure the settings are
correct. Before we make this adjustment
we should have the truck ready to race
(meaning fully loaded with fuel and receiver
batteries), but leave off the body.
For the front, push down on the front
suspension and then let go. When the sus-
pension stops, the front arms should be
level with the bottom of the chassis kick
up. If not, you can make adjustments by
using the shock preload clips that come in
your kit.
Now push down on the back suspen-
sion and let go. The axle driveshafts should
be level. Look at the rear end photo to com-
pare. You can make the adjustment by us-
ing the shock pre-load clips that come in
your kit.
Adjust ride height by add-
ing or subtracting clip-on
preload spacer #6475.
SHOCK SPRINGS
Springs are to keep your car level during acceleration , de-
celeration, and cornering. Stiffer springs will help your suspen-
sion respond more quickly, but because of their stiffness will not
absorb bumps as well. Use stiffer springs in high traction condi-
tions. Softer springs are best for slippery or bumpy conditions.

GEARING
The RC10GT features the ability to change the
gear ratio. The drive reduction of the GT gearbox is
2.60 to 1. Use the following formula to calculate the
final drive ratio:
# Spur gear teeth
———————— x 2.60 = final drive ratio
# Clutch bell teeth
Your RC10GT come stock with a 66 tooth spur gear and a 15 tooth clutch
bell. This combination will provide the best overall performance for most tracks.
Here is a chart showing you different ratios (includes our optional clutch bells):
Clutch Bell: Part # Spur Gear: Final Drive:
14 7609 66 12.26:1
More Acceleration
15 7605 66 11.44:1
16 7606 66 10.76:1
17 7607 66 10.09:1
18 7608 66 9.56:1
More Top Speed
The 14 tooth clutch bell may not fit with a non pull start engine.
The 18 tooth clutch bell may not fit with a pull start engine.
