CEDAR CITY, Utah USA — AeroTech introduced a number of new model rocket motors at the "Manufacturer's Forum" held on Sunday, July 27th during the historic 50th anniversary of the National Association of Rocketry's Annual Meet (NARAM) in The Plains, Virginia.
After discussing the various new products that were released earlier this year, AeroTech/RCS President Gary Rosenfield unveiled to NARAM-50 participants AeroTech's first new "standard" model rocket RMS™ hardware in 17 years, the RMS-24/60. The 24/60 is 24mm in diameter by 95mm in length, and is intended to fit all motor mounts designed for black powder 'E' motors. The motor is a completely new design, and is not compatible with existing RMS-24/40 hardware. The casing has a substantially thicker wall and uses the same thread form found in the RMS-29/40-120 motor. As a result, the 24/60 motor is now the strongest RMS hardware available. The retail price of the 24/60 hardware will be $75.00. The first reload to be made available for the new 24/60 hardware will be the F35W. The F35W uses AeroTech's White Lightning™ propellant and generates a NAR-certified total impulse of 57 newton seconds, a burn time of 1.6 seconds, peak thrust of 12.4 lbs and will be produced in time delays of 5, 8 and 11 seconds (P/N 63505, 63508 and 63511). The propellant weight of the F35W is 30 grams, meaning that the F35W reloads can be shipped via U.S. Mail Parcel Post with no hazmat fees. The weight of the 24/60 hardware loaded with an F35W reload kit is 85 grams. The F35W will be sold in a 2-pack at a suggested retail price of $20.00. Next, Gary displayed a new 29mm single-use 'G' motor using AeroTech's popular Mojave Green™ propellant, the G78G. This motor delivers a NAR-certified total impulse of 110 N-sec with a burn time of 1.4 seconds, peak thrust of 22.9 lbs and time delays of 4, 7 and 10 seconds (P/N 77404, 77407 and 77410). The G78G produces a beautiful emerald green exhaust plume studded with highly visible "mach diamonds". It uses the same new molded case as the 137 N-sec G80T, which includes a molded aft thrust ring. The weight of the G78G is 125 grams. The G78G will ship with a FirstFire Jr. igniter and will be priced at $25.00 each, in delay times of 4, 7 and 10 seconds.
The G78G will also be manufactured in LMS motor kit form as the G78G/L (P/N 77304, 77307 and 77310). The G78G/L motor kits produce identical performance to their preassembled counterparts, but at a lower retail price of $23.00 each and like the new F35W reload kit can be shipped via USPS Parcel Post® with no hazmat fees, as the individual propellant grains weigh no more than 30 grams each. The G78G/L includes a FirstFire Jr. igniter and will be available in the same time delays as the pre-built versions. A key advantage of the LMS is the ability to change or modify delays, and the appropriate delay kits are specified on the LMS motor kit instructions. Gary informed NARAM participants that AeroTech is planning to re-release the previously discontinued 24mm F21W single-use motor in 2008, possibly in time for this year's iHobby Expo trade show in Chicago, IL. The F21W was placed on production hold in October 2005 after AeroTech was unable to obtain phenolic casing of sufficient quality and quantity to continue manufacturing them using the then-current design. AeroTech has designed casing and bulkhead molds similar to those used to manufacture its 29mm single-use motors, and prototype parts have recently been received and were shown at the forum. Testing of the new parts is scheduled to begin in August.
Finally, an update was provided regarding the AeroTech RMS/Hybrid™ system, which was last manufactured in October, 2001. AeroTech has located a supplier of the Pyrovalve™ pellets that are used to control the flow of oxidizer in the RMS/Hybrid motor, and is determining whether to begin acquiring the other materials necessary to resume production of its hybrid reload kits. More information will be released as it becomes available. No user certification will be needed to purchase RMS-24/60 hardware, F35W reloads and G78G & G78G/L motors, though customers must be at least 18 years of age. AeroTech anticipates being able to accept orders for the new products by late August, with deliveries beginning in early September. Instructions, RMS assembly drawings and the official NAR certification documents for the F35W, G78G and G78G/L are available for download in PDF format from the AeroTech Resource Library at http://www.aerotech-rocketry.com/. AeroTech Consumer Aerospace is a division of RCS Rocket Motor Components, Inc., Cedar City, UT.

Re: AeroTech reveals new RMS hardware, motors at NARAM-50
First the 24/60 then the 24/120...right?
Excellent work, thanks for the update and new products.
Bring the back the Hybrid line-up...the petition starts here!!

Sweet. What other loads are coming for this case?

As far as I know nothing has been announced yet. I'm sure more will come - just not aware what they might be. I suspect you will see Green, Red, and Blue at a minimum.

I would like to know more about the tanks given the discussion earlier on the topic with input from Contrail. The pre-filled hybrid market could be a great boon - as long as tank dangers are under control.

That's what I'm thinking. I'd love to see a 24mm G, but with an impulse limit of 60 on that case, I'm betting that's not to be...yet...

Re: AeroTech reveals new RMS hardware, motors at NARAM-50
Gary of Aerotech has done a good service to the industry by releasing and announcing so many innovative products at NARAM-50. The commitment these new lines show in terms of mold capitalization, very easy access, and shipping is very good news indeed.
Sensational job Gary Rosenfield.

Re: AeroTech reveals new RMS hardware, motors at NARAM-50
The 24mm system being introduced seems designed to fit in Estes E9 mounts. That is exciting. There is no technical reason why Aerotech could not later release a 120ns and 180ns version of the system with the typical propellants they offer. There may be an ATF issue above 120ns since the law now specifically regulates motors "intended" to have over 62.5g propellant which a 180 or 240ns system certainly would, despite them being entirely mailable under USPS, and exempt under FAA! The quagmire proffered by ATF illegally declaring APCP containing over 15 micron AP "an explosive" is staggering.

Tank dangers? They must not be too serious as I have owned and used an Aerotech 54mm hybrid since 1996.
It is a DOT approved tank. Mine is stamped "DOT-E7737-1800".

That's the kind that Tom said was safest. So they are DOT - good to know. What size tank is that? Tom's comments were about NON-DOT tanks like HyperTEK uses being used for pre-filled hybrids.

The BATFE believes that any fuel and oxidizer that burns needs to be regulated.

That depends on temperature. If what you are driving at is the actual volume of the tank, 440cc.

Yup that was it. Trying to get an idea of how this compares with HyperTEK which is expressed that way. Thanks!

I think the main concern with any tank, but of course specially with pre-filled tanks is "impact victims".
Imagine a tank that sustained a dent from a "ballistic recovery", say from hitting a stone.
If it's filled on the pad, structural damage may reveal spectacular but not really dangerous results.
If filled by hand however, you want to be sure that it doesn't rupture at all before starting the fill.
So tanks that went through a recovery mishap should be examined and possibly tested before using them again. Even without a visible damage, unless it safely can be determined that the motor didn't experience direct mechanical impacts.
The second thing to really watch out is propper installation of the pyrovalve.
I like the AT hybrid system because it doesn't take complicated and expensive ground equipment and because, once assembled, it handles like a normal solid fuel rocket motor (except CG shift of course  )
