Fast Light Rocket Engines
These are quick little rocket engines! Great for younger enthusiasts like Cub Scouts, RA’s, GA’s and small school demonstrations. Fast thrust get the rocket in the sky quickly, the quick burnout keeps the rocket in sight and these are cheap when bought in bulk amounts for multiple flights and several hours of excitement!

good first shot engine
This is one of my favorite engines to launch my Astron Eliptic on as a two stage. it goes up, this second stage ignites and it gives the experience of two stages w/o loosing a rocket. This is a good engine to test wind conditions or test a model on its first flight.

Favorite
This is my all- around favorite mini rocket engine. The 2 second delay seems about perfect for most of my mini rockets.
