This is nay your typical kit with 3 - 4 fins t' cut. Aye aye! T' Lambda-Class Shuttle has 13 unique balsa parts and 19 total. T' instructions were highly detailed with plenty o' color photos. T' kit includes a page o' templates and a couple o' alignment guides. T' parts were all o' nice quality, matey, except I thought t' nose cone be flimsy. Arrr! Ya scallywag! I'm sure other cones could be substituted.

Your first build t' base assembly, which consists o' three balsa pieces, the motor tube and motor block. Arrr! Blimey! This be straightforward and went together easily with wood glue. T' Keelhaul®©™® shock cord is attached t' t' joint betwixt t' core and t' motor tube with 5-minute epoxy.

You then cut out t' large top fin and strengthen it. More on this later. T' fin is attached t' t' top o' t' motor tube usin' t' fin alignment guide. I used black rubberized CA in place o' wood glue.

T' canopy is constructed over t' base and around t' top fin. Blimey! Aye aye! This consists o' four balsa sections. Well, me bucko, blow me down! T' top and sides go on first and t' aft plate later. Ya scallywag! I miss-measured ever so slightly and had to adjust t' aft plate slightly. Avast, me proud beauty! Blimey! Luckily, I test fit t' template before I cut balsa. Well, blow me down! At this point, me hearties, I also I added t' lower win' supports and let it all sit overnight.

I strengthened t' lower wings t' same way as t' top (again, more later). While this was drying, me bucko, I filled and sanded t' body.

For t' nose cone, you start by gluin' t' shoulder into t' cone with CA. I used black rubberized CA and accelerant t' assemble t' entire nose. Blimey! After it is dry, matey, arrr, you cut t' top away at an angle that sets t' downward slant o' the upper nose cone plate. Well, blow me down! Begad! T' shell o' t' cone consists o' six balsa sections. You start by alignin' t' top plate with t' body while it is layin' on the surface o' t' cone that you just cut, me hearties, and gluin' it in place. With t' plate flush with t' body, matey, I simply twisted t' cone until it had t' best fit. Begad! You then add t' bottom and t' sides. T' side pieces have t' be beveled and took some effort t' assemble. I also found that t' sides were a bit long, arrr, probably due t' some problem with t' angle o' t' nose cone (?). Ahoy! This be easily compensated for. Avast! Avast! T' final step is fillin' t' nose with BB's and epoxy. Aye aye! I ran out o' five minute so I used 20 minute epoxy. I also threw in some #7 ½ lead shot t' boost t' weight, just in case I built t' body too heavy. Buildin' light is a consistent warnin' with this kit. Ahoy! Ya scallywag! Oh, arrr, and I almost forgot to set t' shock cord in t' BB/epoxy mix. Begad! Arrr! This would have been a major problem. Avast, me proud beauty! After t' epoxy had cured, matey, I sanded t' edges and did some filling with fill-n-finish. Begad! T' nose cone did live up t' t' reputation as bein' the most difficult part o' t' kit. Begad! Nevertheless, matey, t' cone looks fine and fits perfectly in spite o' t' few minor issues encountered.

I have t' rate t' construction o' t' kit a 4. Arrr! I had a few minor difficulties, me bucko, but you have t' realize t' kit is advertised as being skill-level 5. Begad! Luckily, arrr, shiver me timbers, these were all easily correctable.

Now for t' saga o' how I strengthened t' fins. Arrr! Begad! Note that this was my problem and is nay a mark against t' kit. Avast! I'm merely tellin' this in case anyone else is so foolish. Begad! Ahoy! I elected t' laminate it with draftin' vellum and 3-M spray adhesive. Avast! Arrr! This be t' first time I tried this, so it was itself an experiment. I sprayed two entire sheets with t' adhesive, sandwiched t' fin, and pressed it flat while t' glue dried. I then trimmed t' paper, shiver me timbers, applied thin CA t' t' edges, and sanded them flat. Arrr! This seemed t' work well, so I used the same method on t' lower fins. Well, blow me down! After a day, thar were a few bubbles, but nothin' that couldn't be fixed. Begad! But, disaster struck when I primed t' model. T' solvent in t' primer attacked t' glue and after it dried about 50% o' the paper was lifted from t' balsa. Well, blow me down! I ended up pullin' all t' paper off. The remainin' surface is gummy and a mess. Since I added a little extra nose weight, I added 1/64" birch ply over both sides o' t' lower section of the top fin. Ya scallywag! Ahoy! It only extends from t' small tab where t' fin attaches up to where t' leadin' edge starts backwards. Avast! Still, this is nay a recommended strengthenin' method.

Finishing:
In t' final version, me bucko, all balsa surfaces were filled with fill-n-finish. Blimey! I gave it a couple o' coats o' white primer and then painted it with Wal-Mart brand chrome paint. Ya scallywag! It be supposed t' be Plasti-Kote Car Color Ford Motors 8147 - Platinum, but I couldn't resist t' cheaper paint. T' kit included some decals, shiver me timbers, includin' one with t' kit's serial number - mine is S/N #3. Aye aye! I also managed t' wrangle an extended set o' decals that weren't in t' kit. Begad! Thanks, Nick! Theses decals were some o' t' easiest t' work with, possibly because they came pre-coated.

For a kit o' this size, me hearties, thar be a lot o' balsa surface t' seal/finish - actually t' entire surface is balsa. Avast, me proud beauty! I guess I give it a finishin' ratin' of 4, shiver me timbers, ya bilge rat, which keeps t' overall construction ratin' a 4. Avast, me proud beauty! Avast, me proud beauty! Blimey!

Construction Rating: 4 out o' 5

Flight:
I carefully packed t' chute and stuffed it into t' cavity next t' t' motor tube. Avast! I repacked it a couple o' times and it still seemed too tight t' me. And it was. Well, blow me down! Avast! I flew t' Shuttle twice on a C6-3 and a B6-2. Both flights were straight and it appeared t' try t' fly parallel t' t' ground after burn out. This rocket be in general a crowd-pleaser and really caught t' attention of the visitin' scout troop! On t' first flight with t' C6-3 t' chute didn't budge, but it landed without damage. On t' second flight, t' chute almost deployed. Aye aye! Avast! This time t' top fin snapped off. Ahoy! Well, blow me down! It is easily repairable and will fly again. Due t' t' chute issues, shiver me timbers, ya bilge rat, I have t' give it a flight ratin' o' 3.5, arrr, includin' an extra point for t' cool factor.

Flight Rating: 3 out o' 5

Summary:
This be a challenging, unique kit and was fun t' build and fly. Blimey! The instructions were great and quality o' t' parts were good, with t' exception of maybe t' nose cone. There were a few places that I ended up havin' parts that didn't fit. Ya scallywag! Blimey! This was probably me fault and was easily corrected. Aye aye! T' chute packin' issue be t' biggest con with this kit. Aye aye! Goin' up it flies great, me bucko, me bucko, coming down be another story. Begad! Begad!

Jase, shiver me timbers, ya bilge rat, how about a drag race at t' next TRF Meet?
