AeroTech/Quest is pleased to announce the Tripoli certification of our new N2700W-PS 75mm RMS™ Reloadable Motor System™ rocket motor reload kit designed for use with AeroTech’s new RMS-75/10240 Rocket Motor Hardware. This powerful new rocket motor has been specifically designed for use as an upper stage sustainer motor for the $10,000+ AeroTech Space Challenge™ competition. This new event challenges individuals, groups and teams to fly to the “Karman Line” or 100 km (62 miles) above ground level using certified AeroTech high-power rocket motors totaling no more than 40,960 N-sec. Developed for use with our new matching RMS-75/10240 motor hardware, this new 75mm rocket motor is perfect for upper stage use coupled with our 98mm O5500X DMS™ rocket motor as the booster, in an attempt to reach and surpass the defined edge of space. The new N2700W-PS 75mm RMS rocket motor reload kit will be available mid-2025 and the new RMS-75/10240 RMS rocket motor hardware is available now.
The N2700W-PS rocket motor reload kit delivers an impressive 10,322 N-sec (2,320.4 lb.-sec) of total impulse, making it the highest performing 75mm RMS rocket motor currently available, with a 3.8 second burn time and an all-up weight in our new RMS-75/10240 rocket motor hardware of 19.97 lbs. (9,058 g). Featuring a 4-grain core burning propellant design using AeroTech’s aerospace-grade White Lightning™ propellant formulation, the peak thrust is 4,625 N (1,039.7 lbs.) with an average thrust of approximately 2,717 N (610.8 lbs.) and a propellant weight of 5,275 g (11.63 lbs.). White Lightning, AeroTech’s most popular propellant formulation, produces a brilliant white exhaust plume with lots of bright white smoke and a throaty roar at lift-off. Although the N2700W-PS produces delay smoke, it is a “plugged” rocket motor that does not include an ejection charge and requires the utilization of an electronically-activated recovery system. The RMS-75/10240 rocket motor hardware is a standard 8-grain length case and the 75mm N2700W-PS RMS reload kit features 4 longer “double length” grains for this new RMS motor system. Originally intended as a second stage sustainer rocket motor, the new N2700W-PS RMS rocket motor reload kit together with the new RMS-75/10240 rocket motor hardware can deliver excellent performance in a single-stage rocket vehicle.
Unfortunately, this new rocket motor reload kit cannot be sold or used as a high-power hobby rocket motor in California due to OSFM regulations. The 75mm N2700W-PS (No. 13270P) RMS Reload Kit ships with a standard FirstFire™ Initiator, has a suggested retail price of $779.99 each and may be purchased by consumers 18 years of age or older with a Level 3 NAR or TRA Certification or by educational institutions, government agencies or licensed Commercial entities.
The RMS-75/10240 (No. 7510C) rocket motor casing with Stainless Steel Forward Seal Disc (SSFSD), but without forward and aft closures, has a suggested retail price of $699.99.
To assist competitors entering the $10,000+ AeroTech Space Challenge™, we have also developed the following new RMS motor closures to accompany our new RMS-75/10240 rocket motor casing.
75mm “No Smoke Charge” Plugged & Threaded Forward Closure(No. 75FCPTNS) - $149.99 ea.
75mm Flush Aft Closure (No. 75FACC) - $119.99 ea.
75mm Tail Cone Flush Aft Closure (No. 75TFAC) - $209.99 ea.
Complete RMS-75/10240 Rocket Motor Hardware System (No. 7510M)
(Includes No. 7510C, No. 75FCPTNS & No. 75FACC) - $921.99 ea.
Certified by the Tripoli Rocketry Association (TRA), the National Association of Rocketry (NAR) and the Canadian Association of Rocketry (CAR).
