18 mm Motors
18mm wide by 70mm long, these motors are the most common of the model rocketry fleet. They range in total impulse from 1/2A (0.626 Ns) to D (20 Ns), and can power small to mid size rockets to altitudes well over 1000 feet. Be sure you review the Model Rocketry Safety Code to make sure your launch site is large enough for the motors you are flying.
