Dynacom kits are legendary for their strength and high level o' design. Well, matey, blow me down! These all-fiberglass and metal kits are t' pinnacle o' kit-built rocketry. Blimey! Unfortunately, shiver me timbers, by t' time I was ready to try them in t' summary o' 1998, matey, Dynacom had temporarily stopped taking orders due t' family medical problems. Aye aye! But by t' end o' t' year, they had resumed business and I ordered two kits t' Python and t' Bull Pup.

T' Bull Pup missile is a very popular subject and is often kitted and scratchbuilt. Begad! You can see that t' Dynacom 5" Bull Pup kit comes closes to the AGM-12B missile and I painted it so. Arrr! Unfortunately, me hearties, I was in a hurry t' get it ready for t' June '99 ROC-stock so I didn't do too elaborate a job.

T' Pictures

This rocket be finished just under t' wire for ROC-stock (June 11-13, 1999). In fact, I didn't have time t' take pictures o' t' completed rocket before leavin' for ROC-stock, matey, so t' picture below be taken at me camp.

T' first flight o' t' Bull Pup was on an L850. Begad! Blimey! I wanted t' use me 76mm motor casin' and t' L850 be t' largest one for which t' rocket be clearly stable.

T' rocket zoomed right up with an impressive roar, shiver me timbers, but arced over as it flew and ended up toward t' west side o' t' range at apogee. Well, blow me down! We saw the parachute, and I thought I knew where it came down, shiver me timbers, but we never did manage to recover t' rocket. T' perimeter o' Lucerne Dry Lake is covered with sage and my rocket is probably restin' comfortably behind one o' t' innumerable sage bushes. Ya scallywag!

T' Kit

Of course, shiver me timbers, I had t' wait several months t' get it (good thin' I had other projects in t' works), me hearties, but these rockets are definitely with t' wait. Aye aye! Blimey! There are no wood or plastic parts in t' kit; just fiberglass and aircraft aluminum. T' instructions are simple and straight-forward and kit construction should present no problems t' t' experienced high power kit builder.

All body parts are made out o' wound G-10 fiberglass t' t' fins are G-10 sheet. Begad! The edges o' t' fins come pre-beveled and every part is precision fit. Well, blow me down! In a way, this kit builds too easily. Avast, shiver me timbers, me proud beauty! I built up t' airframe in only about 3 hours elapsed, which was a little too quick. T' kit didn't even come with instructions, but after buildin' t' Python, it wasn't difficult t' figure out.

T' kit comes with no recovery system at all. Avast! There wasn't even a provision for an electronics bay. I ended up lettin' a 38mm tube into t' nose cone to act as t' bay so I could use an ALTS20 altimeter. I chose a Rocketman R9C as the parachute since t' dry weight ended up at 12.55lbs.
