"The better E alternative"
stumptl
The pluses: These are higher thrust, higher impulse, smaller, and lower weight than the Black Powder E's from the other motor maker. The minus: They do cost a little more, but in this case you get what you pay for. On the other hand, I've never had one of these blow through, and I can't say that for the Black powder E's. ;-)

 
"Good power, nice flame, nice sound"
duanenorris (Richmond, KY)
Fired this motor in a custom build scale Patriot missile. Made an awesome launch. Lots of visible flame, nice roar. Rocket flew great to about 1100 ft. Ejection right on time. Even though I prefer the reloadable for the the price, I will probably end up getting more of these. Rocket info: 32in length, 8oz at liftoff, 56mm Diameter.
