Tuning Tips - Painting, Beginners

Painting:

Your Kit requires a clear polycarbonate body. Prep the body by washing the INSIDE thoroughly with warm water and liquid detergent (avoiding scents or added lotion ingredients). Dry with a clean, soft, lint-free cloth. Use supplied window masks for windows. Apply masking tape to the inside for design. Spray paint (rattle can or airbrush) on the inside, starting with dark colors. Use only paint recommended for polycarbonate plastics. After paint dries (approx. 24 hours), cut along trim lines. Drill or use a body reamer for antenna holes if needed. Use hook and loop tape to secure the body to side rails.

Tips for Beginners:

Before making setup changes, ensure you can drive the track without crashing. Focus on consistent laps. Make only ONE adjustment at a time and test it. If an adjustment improves lap times, record it. If it slows lap times, revert to the previous setup. Periodically check all moving suspension parts; they must be clean and move freely without binding for optimal handling.

Tuning Tips - Front Arm Mount Pill Insert Setups

The aluminum front arm mounts use eccentric pill inserts for fine adjustments to kick-up, pin height, and pin width. Use the supplied inserts (#92014). Standard Position is a reference for changing pill locations.

Pin Width: More distance = wider pivot; Less distance = narrower pivot.

Kick Up: More angle = More kick up; Less angle = Less kick up.

Pin Height: Higher pin = Higher roll center; Lower pin = Lower roll center.

Total Caster Angle: Sum of kick-up angle and caster block angle.

Kick Up Angle Table:

Tuning Tips - Rear Arm Mount Pill Insert Setups

The aluminum rear arm mounts use eccentric pill inserts for fine adjustments to kick-up, pin height, and pin width. Use the supplied inserts (#92014). Standard Position is a reference for changing pill locations.

Pin Width: More distance = wider pivot; Less distance = narrower pivot.

Anti-Squat Angle: More angle = More anti-squat; Less angle = Less anti-squat.

Toe Angle: More angle = More toe in; Less angle = Less toe in.

Pin Height: Higher pin = Higher roll center; Lower pin = Lower roll center.
