As you may have already heard, some Aerotech motors are being discontinued.
Pre-orders are open now through April 15th. After that, we cannot guarantee any availability.
All orders placed will be fulfilled from this final batch, which Aerotech expects to ship as they become available over the next year, as late as April 2027.
Aerotech H14ST-P 29mm x 230mm single-use DMS Disposable Motor System - A081400NTR
The new H14ST-P DMS high-power rocket motor was designed by Gary Rosenfield, RCS/AeroTech founder and president, after developing the H13ST-P for the Hamster Dance competition at Black Rock Desert, NV during the BALLS-28 launch. The new H14ST-P is capable of reaching altitudes over 20,000 feet with an 18.3 second burn time. This low-thrust, long burn high-power hobby rocket motor has the highest total-impulse of any 29mm long burn high-power rocket motor available.
The H14ST-P is offered in two versions, with a built-in thrust ring (P/N 081400) and without (P/N 081400NTR). This is a great rocket motor for both heavier gliders and lighter weight, high altitude rockets as a single-stage or upper stage low thrust / long burn propulsion system. Featuring AeroTech’s fast-burning Super Thunder propellant formulation, the H14ST-P delivers a sharp high-thrust spike followed by a reduced sustain thrust for the remainder of the burn.
The H14ST-P delivers 240.12 N-sec (53.98 lb.-sec) of total-impulse with a peak thrust of 42.13 N (9.35 lbs.). This is a “plugged” motor that does not produce delay smoke or contain any ejection charge. Rockets using this type of rocket motor must utilize an electronically-activated recovery system.
The AeroTech Disposable Motor System DMS is a single-use motor in kit form that is assembled by the user. All of the Aerotech DMS motors use all-disposable components. The nozzle and propellant are already installed.
The H14ST-P is a Plugged/Smoke motor. Plugged reload kits do not utilize a motor-actuated ejection charge. Plugged motors must be used in conjunction with a timer, altimeter or radio-activated recovery system. The motor case comes without the thrust ring.
DMS motors feature a filament-wound fiberglass casing, a glass-reinforced composite phenolic nozzle, a molded plastic bulkhead and RCSs exclusive Super Thunder™ aerospace grade composite propellant formulation, which produces a bright violet-blue flame with a minimum of exhaust smoke. Super Thunder™ motors provide a higher ISP than Blue Thunder™.
This AeroTech motor pack comes with 1 rocket motor and 1 FirstFire™ Initiator. Requires HAZMAT shipping via UPS or FEDEX. The sale of this high power motor to persons under 18 years of age is currently prohibited by federal law. This is a High-Power motor requiring Level 1 High-Power certification through NAR or Tripoli to purchase. Orders containing this item will not be shipped until proof of age (such as a copy of a driver’s license) and proof of Level 1 certification is received.
Certified by the Tripoli Rocketry Association (TRA), the National Association of Rocketry (NAR) and the Canadian Association of Rocketry (CAR).
