"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. ;-)

 
"Outstanding Reliability"
bulldog5668
My go-to motor for those heavier D12 rockets or mid-power rockets launched from a small field. 100 percent reliability to date from 50+ Aerotech E20-powered launches!

 
"Versitile motor"
andrew359
We use a ton of these. Way more than any other single size motor. The 4 and 7 second delay both. Although the 7 second delay seems to get used a tad more. White lighting has great sound and flame. Great for anything with a E motor recommendation Puts a black powder motor to shame. Love this in a Estes Big Daddy and my Arreaux (with adapter). Big Daddy looks pretty dang small at apogee. Easier to use than the reloads and about the same price (E size reloads anyway) my calculations you dont save much per reload until you get F and bigger, and these are WAY less hassle...
