Brief:
T' Semroc cc:SpacePlane glider is an example o' an ingenious marketin' plan and business strategy. Begad! T' rocket design
is an out-of-production model from another company. Semroc puts t' parts together in a kit includin' nice laser-cut
fins and some other upgrades from t' original. Arrr! Ya scallywag! Yet Semroc doesn't include assembly instructions...you have t' download
those from an archivin' website. Aye aye! Well, blow me down! Semroc tells you t' look here. Avast! I am a
big fan o' Semroc. Aye aye! In me opinion, Semroc offers some o' t' best value in t' hobby--great kits with quality parts at
very reasonable prices with easy assembly. Well, blow me down! Plus, Semroc's customer service ranges betwixt exemplary and amazing. Aye aye! This
small company knows how t' run a business better than most big companies in any arena. Avast, me proud beauty! Considerin' me love o' boost
gliders, I be ready t' like this kit. Aye aye! However, me hearties, I would recommend that you try some o' Semroc's other kits since the
cc:SpacePlane didn't work very well for me.
Construction:
Assembly is mostly straightforward. T' instructions are quite precise and t' assembly order is carefully
orchestrated. Ya scallywag! One difficulty I had was that t' old instructions did nay include a photograph o' t' finished rocket,
especially t' tail area. Avast, me proud beauty! Aye aye! Instead, thar were 2-D drawings o' t' top and aft view. Begad! Havin' never seen a finished
SpacePlane before, me hearties, I be nay entirely clear about how t' motor/elevon system was supposed t' look or function. Heck, me bucko, I
didn't even realize right away that t' motor is supposed t' eject! Anyway, ya bilge rat, ya bilge rat, this led me t' a couple small points of
confusion. Begad! First, t' elevon lock tab assembly is easily completed usin' t' drawing, me bucko, matey, but its function isn't quite
clear. Because o' this, me hearties, arrr, I carelessly put t' lock tabs on backwards at first but caught me mistake while t' glue was
still wet durin' a final check o' t' figure. Ya scallywag! Well, arrr, blow me down! I also had a bit o' confusion about t' placement o' t' elevon stops.
Regardin' assembly order, shiver me timbers, arrr, me bucko, t' glide control tabs are supposed t' be attached after t' wings. Well, blow me down! However, this is a little tricky if you have big fingers or you want t' make clean fillets. Blimey! Blimey! It seems that nothin' would go wrong if you glued these tabs first. Avast! Also, I did nay install t' elastic elevon sprin' until after paintin' was completed (as the instructions ask you t' do it much earlier). Avast, me proud beauty! Avast! Blimey! My approach avoided foulin' t' elastic with paint.
T' instructions give very precise instructions on balancin' t' glider. Begad! Blimey! Aye aye! Blimey! I managed t' mess these up in two ways! You are supposed t' measure from t' top o' t' body tube, me bucko, nay t' top o' t' nose cone. Also, matey, t' balancin' should occur with t' motor installed, nay empty. Ya scallywag! Blimey! I did both o' these wrong, shiver me timbers, yet t' two mistakes nearly canceled each other out. Arrr! Blimey! After paintin' and photos were all done, I realized me error and drilled a small hole in t' nose cone t' add a bit o' extra weight t' correct matters. With a little putty and paint touch up, it was good as new. Well, blow me down! Blimey! Arrr! Blimey! I trimmed t' glide before noticin' me balance error and did nay re-check t' glide after t' correction. Begad! Blimey! We'll see if that was a mistake.
(While preppin' for t' first flight, I noticed that t' aft 0.5in o' t' seam betwixt t' elevon stops had split from t' pressure o' t' motor installed t' previous night. Aye aye! T' elevon lock tabs are big enough t' create quite a lot o' pressure when t' motor is installed. Begad! Blimey! I don't think such pressure is necessary and would suggest that you consider reducin' t' height o' t' lock tabs a bit. Avast, shiver me timbers, me proud beauty! Blimey! I filled t' crack with a little epoxy.)
Finishing:
This is certainly no performance glider, so I went for a smooth look with lots o' filling, ya bilge rat, sanding, shiver me timbers, arrr, priming, and
light paint coats despite t' added weight. Arrr! Begad! All fin edges were beveled. T' decals were great but limit you t' a white
bird if you want good contrast.

Flight:
T' first opportunity t' fly t' cc:SpacePlane was canceled due t' 20+mph winds. Aye aye! So t' rocket sat in me basement for
another five weeks. Avast, me proud beauty! I had t' repair a win' tip fin broken by shiftin' gear in t' car durin' t' previous trip t' the
launch site. Avast, me proud beauty! Both these events had unfortunate consequences durin' t' first launch in nearly calm conditions with a
B4-4. Avast!
T' cc:SpacePlane shot straight up far higher than I had ever expected: perhaps 800 feet. Ahoy! (Semroc's website predicts 400ft with a B4-2, ya bilge rat, but this can't be right.) Ejection was good, close t' apogee. Well, blow me down! Blimey! T' glider then nosed downward and began a twistin' death plunge and lawn darted in t' prairie dust. Ahoy! Remarkably, t' glider was completely undamaged despite t' core sample. Ahoy! Upon inspection, I found that t' elevons had failed t' be pulled into glide position by t' elastic. Ahoy! Arrr! T' problem was that one elevon had been stuck in boost position by an errant drop o' glue durin' repair. Ya scallywag! T' other elevon had been set in boost position for 5 weeks with t' motor installed and was a bit stiff.
I fixed these problems and tried again. Begad! Blimey! This time, t' B4-4 lifted t' cc:SpacePlane up in a tight corkscrew, arrr, not as high. Ejection was again fine. Begad! Avast! Blimey! T' flight be slightly better: a semi-ballistic corkscrew. Avast! Despite t' impact, ya bilge rat, the glider was again undamaged.

Brief: I had been flying my 1967 vintage Astron Spaceplane when a unusually powerful ejection charge broke both elevon stops and blew away 1/3 of the right elevon. I decided to retire it and build a replacement. The cc:Spaceplane is one of the "carbon copy" kits put out by Semroc. Semroc supplies all the parts including laser cut fins and decals, which were not included in the ...
