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

Your first build t' base assembly, ya bilge rat, which consists o' three balsa pieces, the motor tube and motor block. Avast, me proud beauty! This be straightforward and went together easily with wood glue. Ahoy! Well, blow me down! 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. Aye aye! Aye aye! 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. Well, blow me down! Avast, me proud beauty! This consists o' four balsa sections. Begad! T' top and sides go on first and t' aft plate later. I miss-measured ever so slightly and had to adjust t' aft plate slightly. Aye aye! Well, blow me down! Luckily, I test fit t' template before I cut balsa. Avast! 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, 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. Avast! After it is dry, you cut t' top away at an angle that sets t' downward slant o' the upper nose cone plate. 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, and gluin' it in place. With t' plate flush with t' body, I simply twisted t' cone until it had t' best fit. You then add t' bottom and t' sides. Begad! Begad! T' side pieces have t' be beveled and took some effort t' assemble. Aye aye! Well, ya bilge rat, blow me down! I also found that t' sides were a bit long, shiver me timbers, me hearties, probably due t' some problem with t' angle o' t' nose cone (?). This be easily compensated for. Ahoy! T' final step is fillin' t' nose with BB's and epoxy. Begad! Ya scallywag! 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! Begad! Oh, and I almost forgot to set t' shock cord in t' BB/epoxy mix. Ahoy! This would have been a major problem. Ahoy! After t' epoxy had cured, ya bilge rat, I sanded t' edges and did some filling with fill-n-finish. Arrr! Well, blow me down! T' nose cone did live up t' t' reputation as bein' the most difficult part o' t' kit. Aye aye! Blimey! Nevertheless, 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. I had a few minor difficulties, arrr, arrr, ya bilge rat, but you have t' realize t' kit is advertised as being skill-level 5. Blimey! Blimey! Luckily, me hearties, these were all easily correctable.

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

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

For a kit o' this size, thar be a lot o' balsa surface t' seal/finish - actually t' entire surface is balsa. Aye aye! I guess I give it a finishin' ratin' of 4, which keeps t' overall construction ratin' a 4. Aye aye!

Construction Rating: 4 out o' 5

Flight:
I carefully packed t' chute and stuffed it into t' cavity next t' t' motor tube. Blimey! I repacked it a couple o' times and it still seemed too tight t' me. Avast! And it was. Well, blow me down! Begad! I flew t' Shuttle twice on a C6-3 and a B6-2. Avast, me proud beauty! Both flights were straight and it appeared t' try t' fly parallel t' t' ground after burn out. This rocket was 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. Aye aye! On t' second flight, shiver me timbers, matey, t' chute almost deployed. Begad! Blimey! Blimey! Blimey! This time t' top fin snapped off. Blimey! Blimey! It is easily repairable and will fly again. Avast! Blimey! Arrr! Blimey! Due t' t' chute issues, me hearties, ya bilge rat, I have t' give it a flight ratin' o' 3.5, includin' an extra point for t' cool factor.

Flight Rating: 3 out o' 5

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

Jase, me hearties, how about a drag race at t' next TRF Meet?
