Q: What is the RPM warranty policy?

A: It is a common misperception that RPM has a "no questions asked" warranty policy. Although we do have the best warranty in the R/C industry, it is not "no questions asked". The following text describes in detail what our warranty does and does not cover, subject to RPM final review.
If you manage to break an RPM molded product under normal operating conditions(1), we will replace that part at no further cost to you(2). Normal operating conditions covers most types of driving conditions that an unmodified, stock R/C vehicle would normally encounter, including most normal bumps, jumps, and road hazards. RPM will not warranty a broken or damaged part if it has been modified in any way (or if the part breaks due to modifications elsewhere on the vehicle that directly affects the RPM part in question). This includes, but is not limited to, drilling, grinding, filing, etc., nor will we warranty any part that has been worn out through extended use and / or abuse. In addition, it is nearly impossible to crush an RPM part under normal operating conditions, therefore crush damage of any sort will not be covered. Please use common sense to determine if the breakage was caused by a materials or workmanship issue. We take great pride in the engineering and craftsmanship that goes into each and every RPM part. Therefore, we take our customer service related issues just as seriously and we will do everything possible to resolve legitimate warranty related claims. RPM reserves the right to final judgment regarding all warranty issues. Every RPM part sent in for warranty review will be reviewed by a member of the RPM staff to determine whether or not the guidelines of the RPM warranty policy apply.
