💡 What is the role of a pinion gear in an RC drivetrain?
In simple terms, it pairs with the spur gear to define the drive ratio and power delivery, and it needs to stand up to heat and wear in rough use.
- It pairs with the spur gear to set throttle response and acceleration - It directly affects top speed and motor load during heavy basher runs - Use the correct shaft size and retention hardware for a secure fit
