- Corally SP12X - Jeff Brown - ROAR Nats- Hobby Plex - 16.03.2008 -

 

The bite was about medium, so I know these changes will be good with high bite. We'll try even more aggressive settings next time we race on high bite.

Front

Front suspension:Corally WC (same as Assoc. dynamic strut) with 10 degree reactive caster blocks, 2 spacers rear and 1 front, 1 1/4 degree camber, raised steering arm ballstuds, threaded axles from Parma
Front springs: .020
Servo mounting: flat, rear mount (ballstuds for steering arms facing forward)
Front width: 165 mm at top of tires
Toe in/out: 0 degrees
Tires: Jaco lilac front, 1.64", full front tire sidewalls glued with CA

Rear

T-bar: Corally 2mm, with center screw on rear pod removed and spacer cut to only have spacers under 2 pod mounting holes, no spacer under front pivot ball
Center shock: IRS VCS shock, front mount raised 1.5 mm and rear mount moved back 6 mm, Silver spring and 30 wt. Assoc. silicone shock oil. (there were no bumps on this track. If this setup is too aggressive or doesn't handle bumps for you, go back to the olive (green) spring, 25 wt. oil, or both)


Dampner Lube: Corally blue. Same comment as center shock, go back to red if necessary.
Ride height: 3.5 mm, chassis level when race ready
Rear pod droop: This is checked by lifting center shock rear mount and measuring height at rear of main chassis. Difference between static ride height and lifted height was 1 mm
Rear width: 171 mm
Tires: Jaco yellow rear, 1.74", 1/2 rear tire sidewalls glued with CA

Chassis: stock kit chassis

Body: Protoform Speed12

Batteries: Team Kwik Ener-G 4600 NiMH (Note: the SAME pack of batteries was used twice in practice, in all 4 qualifiers, practice the morning of the main, and in the main)
Motor: handout CO 27T tuned by Team Kwik

Comments:

Tires: We tried 2pink front and rear, 2pink fronts with yellow rear, and lilac fronts/yellow rear. Lilac front/yellow rear was the best (all Jaco tires).
