Review Summary

The reviews highlight that these motors are powerful, loud, and produce impressive smoke trails, making them ideal for demonstrations and launches with strong performance, often propelling rockets to significant heights. Many appreciate the long, slow burns and realistic effects, though there are concerns about the reliability of older igniters, with some failing to work consistently. Overall, the motors are well-regarded for their value and impact, with hopes for continued production.

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.

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