CEDAR CITY, Utah USA — The National Association of Rocketry (NAR) Standards & Testing (S&T) Committee has certified AeroTech's new 24 X 95mm F30FJ single-use model rocket motor.

AeroTech's new F30FJ Black Max model single-use rocket motor, shown at the top, was recently certified by the NAR S&T. The F30FJ's dense black exhaust is shown in the bottom photo lofting an AeroTech Arreaux. Liftoff photo: Bob Sanford.

The F30FJ features a molded phenolic casing with a built-in thrust ring, a molded plastic bulkhead and uses AeroTech's Black Max™ propellant which produces a dense black exhaust. The F30FJ will be available in three time delays: F30-4FJ (P/N 63004), F30-6FJ (P/N 63006) and F30-8FJ (P/N 63008).

The NAR's certified total impulse for the F30FJ is 47 N-sec. Other statistics include a burn time of 1.51 seconds, an average thrust of 30.4 newtons, peak thrust of 40.6 newtons, propellant mass of 31.2 grams and an initial mass of 70 grams. It may be used interchangeably in kits designed for other 24 X 95mm motors such as the AeroTech F32T and the black powder E9. The F30FJ weighs only slightly more than the E9, but delivers over 1.6 times the total impulse.

The F30FJ single-use motor will be available from AeroTech and its dealers at a suggested retail price of $15.99 each. AeroTech is accepting orders for the F30FJ now and anticipates shipments to its dealers to begin in approximately 4 weeks. The F30FJ is being submitted to the California Office of the State Fire Marshal (OSFM) for approval of sale & use in California.

Motor instructions and the official NAR certification document for the F30FJ are now available for download in PDF format from the AeroTech Resource Library at http://www.aerotech-rocketry.com/.

#1 Re: Article: NAR S&T certifies new AeroTech F30FJ Black Max motor

New motors are great but what would really be nice would be to see a reduction in the prices for single use Aerotech motors. I think that the current high prices may prevent some fliers from moving up in motor size from low to mid power.

When I got into mid power rocketry a pair of F20 Econojet motors was about $14 and a pair of G35's was $17. It was a good transition for me without having to buy a 29mm reloadable casing right away. Later on I bought the casing and now I use all reloads for my F and G powered rockets because single use is expensive.

Of course $14 to $17 prices for two F or G motors was 8 years ago will not return but any reduction in the current prices would help, I think.

Oh...and please bring back the G35W Econojet. That was one sweeeeeeeeet motor!
