This be t' standard Estes Bullpup 12D kit, shiver me timbers, modified with a small payload bay betwixt t' forward fins and t' nose cone, me bucko, and a engine mount pulled slightly rearward t' allow for a metal spring-clip for t' motor. It is internally modified with a Keelhaul®©™ shock cord mount and a much longer shock cord.

It be windy, but knowin' how little altitude I got with a B6, I knew a C6 would nay get lost. This time t' motor burned for 2.2 seconds, quite a long time, me hearties, only peakin' in acceleration at 5.7 Gs, ya bilge rat, and averaged 1.7 Gs for t' 2.2 seconds. This motor was a slow burner, pushin' t' Bullpup t' 83 mph. Like t' B6 it turned into t' wind, but more so as it was a longer burn. Then it coasted for 2.9 seconds and reached apogee o' 300 feet even. T' delay burned slow also, for 5.9 seconds. In those last three seconds it dropped 118 feet and was pickin' up a lot o' speed.
When t' parachute finally saw t' air, it tore completely off t' shrouds. T' rocket then fell at 24 mph and landed 300 feet upwind, but no damage other than t' parachute, which floated down a minute later. Total air time was 12.9 seconds. While t' engine choice had too much delay, other factors in this flight’s failure was t' long-burnin' delay o' this particular Estes motor, and t' very thin shroud lines which more easily cut through t' plastic parachute. This rocket needs a C6-3 for sure.
