I am very impressed with these motors, they are well built, fit the 18mm mount well. the performance of the motor is amazing. they out preform the Estes B motor by miles. The noise and power is amazing to work. Will be using these motor again.
Great little motors. They fit the 18mm mount well - beware, there are plugs in the pack, they're just very small and they come packaged with the igniters. The performance of the motor is amazing. They so indeed out-preform the Estes B motor but with different launch characteristics. They generate less smoke than an Estes motor and the flame is smaller but the noise is oh so much more satisfying! These are perfectly sized to fit Estes 18mm motor mounts and are just as easy to dispose of as Estes motors.
