Your Castle ESC is warranted for one (1) year from date of purchase to be free from manufacturing and component defects. This warranty does not cover damages caused to your motor or controller from abuse. Abuse includes, but is not limited to, incorrect wiring, over-voltage, overloading, improper gearing, improper motor selection, incorrect controller settings, insufficient batteries, or inadequate connectors. Always monitor your ESC and motor temperatures during the first run after modifying your system to ensure they stay within the safe operating limits.

Warning: Drag and speed run setups are inherently abusive and exceedingly hard on all electronic components. Every component in the configuration can be strained, weakened or worse without extreme caution, an understanding of electric theory and advanced knowledge of all aspects of the RC hobby. High speed runs and drag racing are the most 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. Castle does NOT warranty products used in these abusive applications.
