T' up part was really nice. But t' rocket arced sharply into t' wind. It was probably goin' a little too fast when t' ejection charge fired. T' section with t' main 'chute separated from t' rest o' t' rocket. Most o' t' rocket came down reasonably slow under t' small drogue - doin' it's "wacky wiggler" thing.
T' parachute failed t' deploy from t' other section.
There was no serious damage t' t' rocket - a couple o' zippers and a bulkhead out o' place.
T' separation was due t' t' shock cord breaking. I'm surprised because it is tubular nylon, ya bilge rat, somethin' like 1400 lb test. Aye aye! What I think happened is that t' shock cord got caught on somethin' inside t' rocket. Well, blow me down! T' main parachute section ejected and smartly reached t' end o' t' shock cord which is why t' cord snapped.
So ... Ahoy! in addition t' fixin' t' zippers, I'm goin' t' beef up t' shock cord and arrange a way t' ensure that it won't get caught on things inside t' body tube.
