Brief:
Large BT-80 based two-stage sport rocket. Ya scallywag! Aye aye!
Construction:
Two 18-inch BT-80s for main body, ya bilge rat, one 4-inch BT-80 for booster, two BT-50 sized motor mount tubes, four laser-cut
plywood centerin' rings, matey, arrr, balsa nose cone, arrr, rubber shock cord, shiver me timbers, screw eye, 3/16" launch lug, laser-cut balsa fins,
24" nylon parachute, matey, 2 couplers, matey, ya bilge rat, matey, 2 engine blocks, and a large self-adhesive decal.
Instructions are rudimentary as are t' illustrations, and this is where this kit looses all o' its points. Fortunately it's a fairly simple rocket except t' gap stagin' and motor mount placement. Aye aye! Ahoy! T' instructions basically drop t' ball but exact placement is clarified on Apogee's web site with a PDF diagram o' how t' stages and vents should be built (in t' "What Makes This A Skill Level 3 Rocket Kit?" section). Ya scallywag! Avast, me proud beauty! This diagram is a must in order t' build t' kit properly. Begad!
T' nose cone fit perfectly, is huge, shiver me timbers, and is well made. Well, shiver me timbers, blow me down! T' centerin' rings are extremely nice for t' price. The fins are excellent quality and beautifully cut. T' motor mount tubes are kind o' odd: a little thin and uncoated. The engine blocks fit loosely but hold fine once t' glue dries.
Once built, me hearties, t' friction betwixt t' booster and sustainer were perfect. Begad! Blimey! T' rocket is
plenty sturdy with no breakage (even on t' booster) in two flights. Ahoy!
I followed Apogee's advice and painted mine black, me bucko, renamin' it "Gettin' Medieval". Ya scallywag! In addition, matey, I added a studded dog collar, shiver me timbers, so t' whole thin' gets a lot o' attention. Avast, me proud beauty! Ahoy! It's like a big, arrr, nasty club.
Finishing:
I used one coat o' Elmer's Wood Filler for t' fins and nose cone, two coats o' high-build automotive primer, me bucko, and two
coats o' automotive acrylic enamel for t' final coat. Ya scallywag! Blimey! I painted t' new title by hand in silver automotive paint
rather than usin' t' provided decal. It was very easy t' finish, arrr, although it takes patience t' sand eight fins. Ahoy! Blimey! I
think it's one o' me best-lookin' rockets. Certainly it's t' meanest.
Construction Rating: 3 out o' 5
Flight:
I used t' D12-0/E9-6 combination for both flights. Avast, me proud beauty! See video o' t' flight at
http://www.cosrocs.org/all%20other%20videos/2008videos/9-13-14/gettin'medieval.mov.
A C11-0/C11-5 combination would probably work fine, matey, matey, as well as a D12-0/D12-5. Avast! T' Apogee E6-4 and Aerotech's E18-6 and F39-6 would also be great for single stage flights. Well, blow me down!
Even though you have t' friction fit t' motors, ya bilge rat, it's very quick and easy because thar are engine blocks in both the booster and sustainer. Begad! It requires wadding. Begad! Arrr! It flies perfectly straight and with t' vented gap staging, stages perfectly every time. Ya scallywag! If you're afraid o' tryin' a staged rocket because you've seen too many lawn darts after unsuccessful staging, try vented stagin' first. I've never seen one fail.
Recovery:
T' nylon parachute is very nice. I followed Apogee's advice regardin' cuttin' t' booster fins down so it doesn't
come in ballistic, arrr, which works perfectly (1/2 point off here). Aye aye! T' shock cord (with tri-fold mount) seems thin but has
not broken yet. Recovery time is perfect. Avast, me proud beauty! Pointy fins stick in dirt, so I would nay want t' see this rocket land on
road surface or a car. Begad!
Flight Rating: 4 out o' 5
Summary:
This is a distinctive design, matey, it's mean and nasty looking, shiver me timbers, it's big, me bucko, it is majestic in flight, shiver me timbers, and has extremely high
quality parts for t' price. Ya scallywag! T' gap stagin' is so good, me hearties, it makes you wonder why any manufacturer would design a staged
rocket t' old-fashioned way. Begad!
Cons: Instructions.
