A Lor of Fun
By jamiekitchen November 22, 2013
I usually use these with the 7 second delay on days when the wind is calm and I can send my smaller rockets up to high alitudes without worring about them drifting off. Last weekend however I traded the 7 second delay for a pack of these with the 4 as I had severalheavier rockets that I wanted to launch but it was too windy for my 29mm F motors. I fitted an adaptor amd used one of these and I have to admit, I was pretty surprised at how fast it left the pad. The delay was spot on as the rocket was just arcing over at appogee. I ended up having to walk for a bit to recover it as the altitude was more than I expected. I have probably used these motors several dozen times and have never had a problem with them. They seem to light easy with both the Surefire and the Copperhead igniters.

fun little motor
By jeffnjen1 August 2, 2013
I love these motors. They don't have the problems that black powder E's have and they really get up and go.

Great all around motor
By andrew359 February 16, 2016
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!
By Craig M February 8, 2016
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!
