HYBRID BLACK POWDER ROCKETS - by Steve La Duke. In this 100-minute seminar, Steve demonstrates black powder rockets that whistle! See the traditional black powder tail, get the expected snort, but now discover the secret to making them whistle. Steve shows you his special nozzle material, how to avoid "ram jam", make anti-stick spindles. See how to figure stick length and an easy-to-make header tube. Learn the difference between benzoate and salicylate. Steve is joined by John Steinberg, who adds his considerable rocket experience. Recorded at the 2001 PGI convention in Appleton.
