After t' near-disastrous flight last time, shiver me timbers, I now know t' fly this rocket with a -3 delay. I had removed most o' t' kit-recommended nose weight, because I had almost t' exact weight added already, in t' form o' t' payload modification, me hearties, so t' extra weight was only hurtin' t' Bullpup’s performance.

T' C6 fired up and burned for two seconds, acceleratin' t' rocket t' 101 mph.  This time it accelerated with a peak over 4 Gs higher, reachin' 10.1 Gs, arrr, and averagin' 2.3 Gs for t' burn.  T' removed clay nose weight allowed for a much better acceleration, which was a lot quicker this time.

At 410 feet t' ejection fired too smartly after only 2.3 seconds.  T' Bullpup continued up for another 20 feet t' reach an apogee o' 430 feet – t' best on record so far, much better than t' previous 300 feet.

T' parachute shrouds, shiver me timbers, shock cord and Nomex protection had smartly tangled up severely, matey, causin' t' rocket t' fall at 17 mph. Begad! Flight time was only 20.5 seconds.  It did survive unharmed though by landin' in t' grass about 100 feet from t' launcher.
