💡 What is a pinion gear set used for in RC cars and how should you choose the right size? A handy guide for gearing: - Pinion pitch must match spur pitch for clean mesh - Higher tooth count increases top speed but adds motor load - Use 5mm bore pinions on 5mm shafts for 1/8 and 1/10 scale platforms - After changing pinion, monitor motor and ESC temps to prevent overheating
