Instant improvement in speed by changing to a 55T spur and a larger pinion to match the spur – this is about the fastest you can get with a stock 540 motor.
RC enthusiasts often experiment with different gear ratios, including using larger pinion gears, to optimize their cars for specific track conditions. In certain situations, such as long straightaways on a track, a higher top speed may be advantageous.
Larger pinion gears can be used to better match the characteristics of the motor. Some motors may perform more efficiently or deliver higher speeds with a specific gear ratio, and adjusting the pinion gear size allows users to find the optimal balance.
