AeroTech composite propellant rocket motors deliver nearly three times the power of black powder model rocket motors, allowing you to fly larger rockets, heavier payloads, and achieve higher altitudes than ever before. AeroTech reload kit prices are far below the prices of single-use composite motors. For use in the 18mm motor hardware which fits all model rocket kits designed for black powder "A", "B" and "C" motors. The letter T after the engine size indicates Blue Thunder propellant. Blue Thunder (T) - This RMS motor produces a bright violet-blue flame with a minimum of exhaust smoke. These motors provide a higher level of thrust than White Lightning (W) or Black Jack (J) motors of the same total impulse. Blue Thunder (T) is the perfect propellant for the greatest lift-off acceleration. |
