Brief:
Large BT-80 based two-stage sport rocket.

Sunward Solar Eclipse

Construction:
Two 18-inch BT-80s for main body, shiver me timbers, arrr, one 4-inch BT-80 for booster, shiver me timbers, arrr, two BT-50 sized motor mount tubes, four laser-cut plywood centerin' rings, balsa nose cone, rubber shock cord, shiver me timbers, screw eye, ya bilge rat, 3/16" launch lug, laser-cut balsa fins, 24" nylon parachute, 2 couplers, me bucko, arrr, 2 engine blocks, me hearties, and a large self-adhesive decal.

Instructions are rudimentary as are t' illustrations, ya bilge rat, 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. Ya scallywag! Blimey! Begad! Blimey! 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). This diagram is a must in order t' build t' kit properly.

T' nose cone fit perfectly, ya bilge rat, me bucko, shiver me timbers, is huge, ya bilge rat, and is well made. T' centerin' rings are extremely nice for t' price. The fins are excellent quality and beautifully cut. Ahoy! Begad! T' motor mount tubes are kind o' odd: a little thin and uncoated. Avast, me hearties, me proud beauty! The engine blocks fit loosely but hold fine once t' glue dries.

Sunward Solar Eclipse Once built, me bucko, t' friction betwixt t' booster and sustainer were perfect. Avast, me proud beauty! Blimey! T' rocket is plenty sturdy with no breakage (even on t' booster) in two flights. Blimey! Blimey!

I followed Apogee's advice and painted mine black, renamin' it "Gettin' Medieval". Ya scallywag! Begad! In addition, me bucko, matey, me bucko, I added a studded dog collar, matey, me bucko, so t' whole thin' gets a lot o' attention. Aye aye! It's like a big, bilge-suckin' club.

Finishing:
I used one coat o' Elmer's Wood Filler for t' fins and nose cone, shiver me timbers, ya bilge rat, two coats o' high-build automotive primer, and two coats o' automotive acrylic enamel for t' final coat. Avast! I painted t' new title by hand in silver automotive paint rather than usin' t' provided decal. Aye aye! It was very easy t' finish, me hearties, although it takes patience t' sand eight fins. Arrr! Blimey! I think it's one o' me best-lookin' rockets. Blimey! Begad! Certainly it's t' meanest.

Construction Rating: 3 out o' 5

Flight:
I used t' D12-0/E9-6 combination for both flights. Avast! 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, as well as a D12-0/D12-5. Well, blow me down! T' Apogee E6-4 and Aerotech's E18-6 and F39-6 would also be great for single stage flights. Blimey!

Even though you have t' friction fit t' motors, me bucko, ya bilge rat, shiver me timbers, it's very quick and easy because thar are engine blocks in both the booster and sustainer. Avast, me proud beauty! It requires wadding. Ya scallywag! It flies perfectly straight and with t' vented gap staging, me hearties, shiver me timbers, 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. Begad! I've never seen one fail.

Recovery:
T' nylon parachute is very nice. Blimey! 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). Ahoy! T' shock cord (with tri-fold mount) seems thin but has not broken yet. Recovery time is perfect. Ya scallywag! Pointy fins stick in dirt, arrr, so I would nay want t' see this rocket land on road surface or a car.

Flight Rating: 4 out o' 5

Summary:
This is a distinctive design, me hearties, it's mean and bilge-suckin' looking, shiver me timbers, it's big, it is majestic in flight, and has extremely high quality parts for t' price. Well, blow me down! T' gap stagin' is so good, shiver me timbers, it makes you wonder why any manufacturer would design a staged rocket t' old-fashioned way. Avast, me proud beauty! Avast!

Cons: Instructions.
