"Great deal!"
The B6-4 is a great motor- Decent oomph for it's size, and it'll get a small rocket moving at a very affordable price point. In this bulk pack, it not only decreases the cost per motor, but also includes extra ignitors, and the all-important recovery wadding. This is specially treated paper to prevent your parachute or streamer from being burned. Between all of this, you end up saving quite a bit of money!

"Perfect, as advertised. Great performance"
Spectacular launch, great reliability. Shot all 25 in one sitting. Scouts were so happy with the height and the show. Each engine performed well.

"almost max altitude"
This works well on semi windy days. This makes it so it doesn't go to high and get caught in a cross wind.
