Steve Laduke has combined the Universal and Hybrid rockets into one design that encompasses 6 different rocket types: Strobe Rocket, Long Winded Screamer, Black Powder Motor, Hybrid Motor, Black Powder Whistle Assist Rocket, and Color Tail Rocket. All new updated formulas and instructions.
Kit consists of stainless steel spindle and aluminum base, and 4 aluminum rammers and puller. Currently available in the ¾" I.D. (1 lb.) and 7/8" I.D. (2 lb.) sizes. In dyno tests done by Steve Laduke on 1" I.D. (3 lb.) hybrid rockets the initial thrust was measured at 49 pounds easily capable of lifting a 6" ball shell with no problem.
Please note: Since most of these rockets have a type of whistle mix in them, these must be pressed and not rammed.
