NOTE:Never leave this product unsupervised when it is powered on. It's important to select the battery, Not all motor and ESC suitable for 3s lipo, It is better for 2s lipo. A wrong tooth ratio can cause the motor to overheat. The motor temperature should be lower than 212 during the operation. Temperatures above 212 will weaken the magnet and may partly melt the coils and eventually damage the ESC (because of strong current)!!! To avoid potential risks such as ESC/motor damage or malfunction caused by overheat, start with a very small pinion first and check the ESC & motor temperatures regularly throughout the run. This is the only way to prevent overheat!!!!
