🔹 For best performance, upgrade to a high-voltage LiPo battery!
1.3 Gear Ratio: The Secret to More Speed
The gear system in your RC car controls its speed and torque.
- Higher pinion gear & smaller spur gear = More speed but lower acceleration.
- Lower pinion gear & larger spur gear = More acceleration but lower top speed.
🔹 For top speed, increase the pinion gear size slightly while keeping the motor temperature in check!
1.4 Weight & Aerodynamics
A lighter RC car is always faster!
- Remove unnecessary parts to reduce weight.
- Upgrade to carbon fiber or aluminum components.
- Modify the car’s body for better aerodynamics.
