Race focused gearing with the 3RACING 48 Pitch Spur Gear 89T

The 3RACING 48 Pitch Spur Gear 89T is suited to racers seeking fine control over final drive without altering suspension or motor gear dramatically. Use it as part of incremental tuning to find the optimal balance between lap time and drivability.

Tuning considerations

When adjusting gearing for competitive events, pair the 89T spur with incremental pinion changes and monitor motor temperature and current draw. Small tooth count shifts allow precise tuning of acceleration and top speed for different track layouts.

Recommended use cases

  • Competitive tuning: Step pinion size in one-tooth increments to evaluate lap time impact.
  • Setup consistency: Maintain consistent backlash and mounting torque to ensure repeatable results during practice.
  • Value parts: Use as an affordable tuning item that yields clear handling and acceleration differences.

How do I quantify the effect of a single tooth change?

Record lap times and motor telemetry with one-tooth pinion adjustments. Expect measurable shifts in top speed and acceleration which are useful when tuning for specific sections of a circuit.

Any advice for heat management after gearing changes?

Monitor motor and ESC temperatures after altering final drive; higher torque setups can raise thermal load so consider cooling or slightly richer gearing if temps climb.

What data should I track when tuning?

Track lap times, sector consistency, motor RPM under load and battery voltage. These metrics show whether a spur/pinion change improves overall performance or just shifts peak power demands.
