"Great all around 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...

"Hooked!"
Craig M (Illinois)
I launched these motors last year on the 4th of July while we were waiting for nightfall. The rocket was an Estes d-region tomahawk. The fist flight for this rocket was a Estes e 9-6 that seemed kinda weak for this size rocket. Then I tried one of these, wow! Took off straight up like it had somewhere to go, and what a flame! lost site of it till fhe shoot deployed. That was my first launch with a composite motor. Now I'm hooked! Thanks to internet, hobbylinc.com and aerotech!

 
"fun little motor"

I love these motors. They don't have the problems that black powder E's have and they really get up and go.
