Nike Smoke PS Model Rocket Kit

This is an easy kit to build. One change I made was to drill a small hole in the forward centering ring and threaded through a length of kevlar. This was tied around the motor tube and fastened with CA. At the forward end of the kevlar I tied a small loop so that it was about 1 below the forward edge of the body tube. I CA'd the loop and tied the length of shock cord to the loop. This helps keep the elastic away from the ejection charge flash. I also use super thin CA and apply a thin layer to the inside of the forward end of the BT (about 1.5) to reduce zippering. I flew this recently on an Aerotech E18-4 reloadable-altitude was approx. 450' and it flew straight as an arrow!
