E20-7W 24/70 Single-Use Motor (2)

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. ;-)

Fired this motor in a custom build scale Patriot missile. Made an awesome launch. Lots of visible flame, nice roar. Rocket flew great to about 1100 ft. Ejection right on time. Even though I prefer the reloadable for the the price, I will probably end up getting more of these. Rocket info: 32in length, 8oz at liftoff, 56mm Diameter.

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...
