"Great motor"
SteveAwesome (Highlands Ranch, Colorado)
I use these for all my heavier D sized rockets and many of my E rockets. the shorter delay mates well for this application. If your launching a really light weight D rocket look to the longer delays but for the larger stuff these are perfect.

"Good Stuff!"
Sends my Estes V2 to about 500'. No duds or cato. Nice gateway drug to mid-power rockets....

A Good engine for the first flight of E enabled rockets with the use of a spacer.

"Great motor for rockets that fly D & E"
These are excellent for rockets that fly on D & E motors when you're on a field that's too small to handle the E load. The trust curve shows the same numbers as the E9, but with a bit shorter burn time.


WARNING: Flammable. Read instructions before use.
