Brief:
Semroc had released a series o' "cc:" (carbon copy) kits a few years ago that were essentially bags of parts t' clone an Estes or Centuri classic, but with no directions, me bucko, instead pointin' t' modeler t' reference sites that archive t' original instructions online. Aye aye! While this was generally a well-received product niche, arrr, t' cc:'s were discontinued in 2007 due t' occasional customer confusion over lack o' instructions.

Fast forward t' 2008--Semroc has brought back t' bag o' parts concept as xKits, me hearties, and now offers them only online, hopin' that if you're on t' ball enough t' get through an online shoppin' cart process, shiver me timbers, you can probably figure out how t' pull up online instructions from Jim Z's site.

T' Space Plane be originally sold in 1961 as t' first mass-produced boost glider kit, shiver me timbers, arrr, Estes number K-3. It features some somewhat complex aspects t' achieve t' transition from boost t' glide--spin tabs for rotational stability, matey, ya bilge rat, and elevons locked in horizontal trim by t' motor, which spits out enablin' them t' sprin' upward.

T' first cc: version o' t' kit was based upon an ST-7 tube size (0.759" OD), but in t' xKit offerin' it now matches t' original Estes BT-30 tube (0.767" OD). Avast, arrr, me proud beauty! T' kit retails for $11.50.

Construction:
T' bag o' parts contains t' typically excellent Semroc quality materials:

• BT-30 body tube, 5.5"
• Balsa nose cone
• Laser-cut balsa fins (time-savin' upgrade from t' Estes version)
• Balsa motor block/bulkhead
• Adhesive plastic hinges/disks (substantially improved over Estes version)
• Trim screws (nylon)
• Lead nose weight
• Waterslide decal (upgrade/not included in Estes version)

Since this is an xKit, arrr, Semroc does nay provide directions, but includes a link t' t' JimZ archive site, ya bilge rat, where the original instructions can be found in both TIFF and PDF formats. Begad! This kit is a close enough reproduction that the original instructions work fine.

Buildin' be somewhat challengin' although you are aided a good bit by t' laser-cut parts. Aye aye! I would rate this in the neighborhood o' a 3 on t' 5 scale o' complexity, me bucko, due t' some o' t' challenges with fit/alignment and trim. Avast! Aye aye! My total build time was just under two hours, me hearties, arrr, arrr, plus finishing.

Construction begins with t' fuselage (body tube). You'll need t' print out t' marking guide form t' original instructions, which is then used t' draw lines for t' wings, me bucko, launch lug and control tabs, plus to cut out t' aft section which later serves as vertical stops/limiters for t' elevons. Ahoy! You then glue in t' balsa bulkhead and "attach" t' nose cone, matey, but I found two things worth tweakin' here. Begad! Arrr! First, ya bilge rat, matey, given today's hot ejection charges, treatin' t' aft end o' t' bulkhead is an absolute must. I used a thin layer o' epoxy. Second, me bucko, you should nay "attach" t' nose cone with any semi-permanent glue yet, shiver me timbers, as t' thin' has nay been trimmed and nose weight will be needed later.

Next comes assembly o' t' wings and elevons. T' wings are initially held together by a pair o' tape disks. Well, blow me down! Blimey! Pay careful attention t' t' orientation, as t' laser-cut parts even have tiny laser-scratched location semi-circles on each win' half for use in placin' t' tape disks. Ahoy! With t' win' halves tacked together (no glue yet!), me bucko, arrr, ya bilge rat, t' elevons are then taped in place at t' trailin' edges. T' tape strips provided is very high tack and rugged--I was impressed. Ya scallywag! Ya scallywag! As long as you don't have any balsa dust on t' surface you're bondin' to, t' tape hinges should prove t' be very durable.

I'll admit I be a bit confused by t' next step, matey, which was bondin' and trimmin' tiny elevon stops. Well, blow me down! Arrr! T' instructions show a part that starts out as a rectangular balsa strip, which is then sanded t' an almost fin-shaped pattern, shiver me timbers, stressin' that t' 3/32" width o' t' balsa stock must be used as t' height o' the finished piece. T' laser-cut parts were trapezoid shaped and usin' t' 3/32" height would have made t' shape irrelevant. Once I started dry-fitting, me bucko, arrr, though, shiver me timbers, I realized that t' trapezoid be designed t' match t' top/interior surfaces o' t' elevons, and that no sandin' was needed--they simply act as small wedges t' form a tight fit once a motor's inserted. Arrr! Avast, me proud beauty! A SLIGHT taper might help make for an easy ejection/transition. Ya scallywag! See close-up photo for how these look once bonded.

T' win' dihedral is achieved very simply--the flexible, taped-together assembly gets a generous bead o' glue t' t' top surface (with t' tape disks), arrr, arrr, and this is then placed upside-down on t' body tube with t' win' tips restin' flat on t' table surface. Well, blow me down! Allowin' for overnight drying, I then added t' stabilizers and spin tabs on t' win' ends (pay careful attention t' t' positionin' o' t' spin tabs--also supported by laser-etched lines on t' balsa parts).

T' last aspects o' construction are t' bond t' elevon lockin' plates t' t' bottom (keeps them from getting pushed below horizontal/causin' a nose-down dive), ya bilge rat, t' launch lug, me hearties, and t' mountin' plates for t' nylon trim screws. T' trim plates were hard 3/32 balsa, shiver me timbers, but Semroc still suggests reinforcin' with a coat o' CA. This is a good idea although in me case t' holes were slightly undersized and reinforcin' with CA should have been done after openin' them up, me bucko, nay before.

An elastic cord is then attached from t' elevons up around t' launch lug, pullin' t' elevons up whenever they're free t' float (e.g., after motor ejects). Aye aye! Begad! T' nylon screws can then be turned t' adjust t' amount o' angle for each elevon, which helps create lift as well as introduce a turn for easier recovery. Begad! In me case, matey, I needed t' use most of t' provided nose weight and then a fair amount o' up elevon for a good hand glide, ya bilge rat, shiver me timbers, and t' glide was very fast.

Finishing:
Normally gliders are best left unfinished other than basic moisture protection such as thinned dope, shiver me timbers, shiver me timbers, but in this case, shiver me timbers, given that it's nay exactly a competition/performance model and that it came with nice decals, I decided t' give it a very light white primer coat followed by two light coats o' gloss white. Avast, arrr, me proud beauty! Blimey! I did nay bother fillin' grains, matey, as that would have just added weight, arrr, but I did sand everythin' down with 320 grit sandpaper before painting, ya bilge rat, and made sure to round t' leadin' and trailin' edges as well.

I finished up by applyin' t' waterslide decals, which were typical Semroc quality--fairly durable, very easy to work with, me bucko, shiver me timbers, and go on smoothly. Avast! I think they really help nail t' appearance o' this model.

Construction Rating: 4 out o' 5

Flight:
Havin' some interestin' experiences lately with "retro" glider-like rockets, ya bilge rat, I decided t' go very low-risk and cautious with this. Aye aye! Avast! First, me hearties, me bucko, I hand-tossed it several times (without motor, and nose cone taped in place). Avast! Avast, me proud beauty! I was still gettin' t' decent but fast glides I'd had from post-construction testing.

I then loaded up a 1/2A6-2. Aye aye! For some reason, ya bilge rat, arrr, t' recommended motors jump from 1/2A6-2 over A8-3 directly t' B4-2 and B6-2. Ahoy! T' only reason for this I can think o' (other than typo) would be that maybe t' -3 delay o' an A8 is too long, as you would nay want t' eject this with t' nose pointed down--the kick would amplify t' dive.

T' boost was fine--only got about 80 feet, but was exactly as planned. Begad! Blimey! It rolled maybe twice on t' way up, so the spin tabs did their job without imposin' too much o' a drag penalty.

Recovery:
T' ejection spit t' motor as designed, allowin' t' elevons t' sprin' up and provide some lift. Aye aye! It took a good second or so for t' transition into glide t' settle, but when it did, I witnessed a pretty good glide. Avast! It be still fast, but trimmed right and had a little bit o' a right turn bias t' avoid sailin' away. It was nay enough t' penetrate the 8 mph winds though, so it got knocked around a little bit.

Overall, matey, shiver me timbers, it was a perfectly fine glide, shiver me timbers, ya bilge rat, and I'm lookin' forward t' sendin' it back up on a full B. Avast! Begad! I just have to wait for a less windy day.

Flight Rating: 5 out o' 5

Summary:
I'm sold on this one--it's a bit complex, but if you read and follow t' directions, ya bilge rat, matey, shiver me timbers, t' precision-made parts should work out just fine and you'll have a pretty good glider. Nay exactly a competition model, shiver me timbers, but very good sport flier and the fact that I can send it up on 1/2A6s even on windy days is nice.

Overall Rating: 5 out o' 5
