WARNING: Drag and speed run setups are inherently abusive and extremely hard on all electronic components. Every component in the configuration can be strained, weakened (or worse) without using extreme caution, observance of electric theory and advanced knowledge of all aspects of the RC hobby. High speed runs and drag racing are the most advanced, aggressive and volatile applications in the RC car hobby. Improper setup or use of this product can result in catastrophic failures of the motor, ESC and/or batteries. As such, there is no warranty for any Castle electronics (including the ESC) when used in conjunction with this motor.
We’ve outlined important product use information below; following these guidelines will significantly reduce failures and increase your happiness and excitement. If you have any questions, just give us a call; we have real people right here in the USA ready to help you get the most (as safely as possible) from your setup.

Water Resistant Design: The sensor board is coated with silicone conformal coating to protect the sensors from moisture. The sensor connections are not water resistant; water can cause signal loss which could result in loss of sensored capabilities. Castle recommended applying dielectric grease to the outside of the sensor wire connections after installation of the wire. Routine maintenance is recommended after running in wet conditions. Please refer to this document for running and maintaining motors in wet environments.
