- Team CRC Generation X - Basic Starting Setup for High Traction Carpet -

 

Our basic starting setup for high bite carpet is as follows;

Front

Magenta front tires 1.65", full super glue for high bite, safety glue for med bite or lower
.45 mm spring with very little preload
Negative .5 degree camber, about -1 for medium grip.
10 degree dynamic blocks
caster - 2 shims back
3.5 mm ground clearance
Long ball front suspension for high bite, short ball with front graphite cross brace for med - low bite.

Mid

Red center spring (copper for more steering on smooth high bite)
40 weight oil
Shock length so rear pod droops .5 mm when held in the air
Shock preload so straight line through chassis and bottom plate when race ready
3.75 mm ride center chassis
Batteries forward for anything hotter than 10.5. Back for 13.5, 17.5

Rear

White side spring with no preload
20 K in tubes
4 mm rear ride height
Brushless offset pod (short hub)
Grey-low rear tires 1.70" for high bite, 1.75 for med - low bite. Maybe Yellow rears with some sidewall superglue.

Notes

Need to test long/short upper arm. Some personal preference and feel overrides a general setup. Typically, long arm makes the car feel more "round" in the corners. Short arm with brace for more center corner turn-in.

Need to experiment with battery position. Battery back makes the car steer big time, forward "numbs" the steering a bit.

Back to front rake angle (higher in the back) adds steering. Can be adjusted for feel.

Pod rake effects rear grip and can be tested. Lowering the rear axle to significantly to raise the pod to high levels like 5 mm and then adjusting the preload to lower the car back down to 3 - 4 mm will give the car more rear grip. Be sure that the car still only has the .5 mm droop when held in the air by the antenna.
