Good Value for single use motors

By: rpquadros

These motors are awesome. I used to buy them for my classroom to do high power demonstrations at the beginning of the course. They're loud and fast- everything the kids wanted! My only issue is the old copperhead igniters that came stock with this pack. They were absolutely horrible. They only worked half the time- wasting time getting them to work instead of having fun launching. Aerotech has slowly been phasing out the copperheads and replacing them with the more reliable igniters. I figure that they should all be replaced by now. If you happen to get copper head igniters, call Aerotech and ask them for new igniters because you'll waste half your day watching your rocket NOT fly.

I have a scratch built B-T Tube rocket and was wondering if this motor will fit my Rocket...

This motor is one to get. Reliable and realistic. I hope they continue production on these.
