Black Powder Rocket Engine with Shock Diamond

WWW.PYROSECRETS.COM Just a test of this small BP rocket engine. Made about and avergae of 7.5 pounds of thrust for a little less than second. Decent for such a small motor. Some frame by frames as well just for the hell of it. Please check out my site at: www.DoranAerospace.com or www.pyrosecrets.com Bob Doran
