This is me sky serpant on a J365 smokey motor. It flew about 2000' with drouge at opagee. Arrr! T' main never deployed because I only used one sheer pin. Arrr! T' result be t' cone gettin' snagged in t' tube. Blimey! Next time ill use 2 sheer pins for an even blow out, me hearties, if that still doesnt do it, me bucko, then fuck it ill never use sheer pins again.
