24 mm Motors
24mm motors can pack a punch, and likely are too large to fly in a school yard or small neighborhood park. They do a great job of lifting large model rockets off the pad with a punch, and sending them high into the air. Total impulse ranges from C (5 Ns) through G (150 Ns) total power. Be sure you review the Model Rocketry Safety Code to make sure your launch site is large enough for the motors you are flying.
