Our Quest Micro Maxx motors are ideal for backyard rocket launching. These motors pack tons of power in their compact, convenient size. Our six pack of Micro Maxx motors are the equivalent of 1/8 A in power capabilities. The Micro Maxx design is true to its name, with maximum power in a micro size. Our small motors are strong enough to send a four-gram rocket up to 75 feet high! Their three-quarter second burn time is followed by a half-second delay and then ejection, launching your rocket. Also included with our Micro Maxx motors are MMX-G2 igniters and igniter holders for safe, efficient and user-friendly launches. Enjoy backyard-designed micro motors on your Quest rockets. These motors will launch your rocket high enough for an exciting, successful flight without sending it too far to recover.
