A minimum diameter carbon fiber rocket on an N10000 Vmax motor. Avast, me proud beauty! Launched on April 18, ya bilge rat, 2010 at t' Three Oaks launch held by t' Team 1 rocket club. Arrr! It had a spectacular CATO about 500 feet in t' air just at motor burn out. Ya scallywag! There was some difficulty durin' motor assembly which resulted in a ~2" gap betwixt grains and was likely t' cause.
