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