Please see manual for Waterproof Usage Guidelines.

Brushless electric motors and ESCs have huge amounts of torque at any given RPM. Using too-tall gearing, or a vehicle that is too large/heavy, can result in damage and/or product failure. Please consult your manual and select gearing suitable for the vehicle and terrain, as damage caused by overloading or abuse is unlikely to be covered by the manufacturer's warranty. Always monitor your ESC and motor temperatures closely after modifying your system to ensure they stay within the safe operating limits.
