Rocket Motor Guide,
Thrust to Weight Ratio’s
This guide was originally created way back in 2001 for a quick reference at our clubs launches.
Some of the motors listed are no longer available or certified to fly. In addition, many new motors and manufacturers are now available. Look to the end of the guide for a simple formula to determine ratio’s for those motors.
Data presented here is a guideline only. Common sense, experience and a little effort on the part of the flyer is required. Use this guide at your own risk. There are several ways to determine the maximum thrust to weight ratio and many factors can impact the ratio, including the rocket design. Always follow your RSO’s decision.
