Great For Limited Areas
If you don't have a large, open field available, stay with the B-Class engines. They have power enough for most standard rocket kits from Estes, and with little to no wind, you won't have to run hundreds of feet to recover your rocket.
estes rocket engines
it works great for the kind of rocket i have! i recommend this engine to everybody.
Awesome engine!
Watch out if you are putting these in a small-ish rocket. Our Alpha III went way higher than we anticipated with the B6-4. However, in the Spirit rocket (much larger and more drag) the B6-4 was perfect.
Great rocket engine
This rocket engine brought our rocket up about 850 ft. and was pretty cool to watch. The rocket first time no problem. This is a great rocket engine to buy.
Great engine.
Perfect for a rocket the size of a Alpha III. Was a blast!!
