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 29mm motor hardware which fits all model rocket kits designed for 29mm motors. The letter R after the engine size indicates Redline propellant. Redline (R) - Distinctly different from its propellant relatives, Redline (R) provides unique visual and thrust characteristics for larger airframes and performance oriented flyers. The proprietary AeroTech formulation imparts Redline (R) with its signature vivid scarlet flame. Redline's burning rate lie midway between that of White Lightning (W) and Blue Thunder (T). Photos don't do justice to the "laser-beam" intensity and color of Redline... you have to see it to appreciate it. |
