Know your Ratios

Before you order your gears and belt drives. Look over our ratios and what parts fit with the motor. If you do not match ratio, belt drive, and KV Motor you run the chance of blowing your RC up, and nobody wants that. We are not liable for any damages made to the product due to over-gearing or under-gearing.
