Warranty: Castle products are backed by the industry's best service and support.This motor is balanced and tested during manufacture and is warranted free from defects in materials and workmanship for 30 days following the original date of purchase. Due to the abusive nature of drag and speed run setups, Castle is not liable for incidental or consequential damages to other equipment such as ESCs and batteries when using this motor and is not responsible for failures resulting from abuse, improper installation, misapplication or alteration.
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. 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.

Tech Notes:
Castle Creations makes the best electronic speed controllers in the industry, possibly the world! Our engineers have spent countless hours integrating features and firmware that no other manufacturers can match.
Speed Controllers enabled with SmartSense use the motor’s sensors to provide smooth starts, excellent torque, and low-speed drivability. Once the motor is turning, it seamlessly transitions to Castle’s ULTRA-EFFICIENT sensorless mode with electronic timing. When running, a motor must transition between different load points and a different timing advance is required for optimal efficiency at each. Electronic timing in SMARTSENSE™ will advance timing automatically for peak performance during all driving conditions. This combines the best of both worlds in an unrivaled HYBRID between smooth sensored startups and high-efficiency sensorless running. Your motor will produce more power and less heat.
