T' Swift BG is one o' t' new kits released by Semroc for NARAM 51. Begad! It is a reproduction o' an old Centuri design. Begad! Although I have had terrible luck with gliders, ya bilge rat, somethin' prompted me t' get started on this one right away. Ahoy! Blimey! It might be t' one t' break t' jinx.
I ordered mine as soon as it be availible and in typical Semroc Time Warp fashion, me bucko, it arrived almost
immediately, matey, even though Semroc was closed for NARAM. Begad! It be also production kit number 10.
Construction:
Construction began by locatin' t' win' and gently sandin' it in its balsa frame and then releasin' it. Ya scallywag! Well, blow me down! Although t' win' consists o' 4 pieces, they are nay yet cut apart at this stage. Aye aye! T' only thin' that marks t' discrete pieces is a line.
With t' win' remainin' in one piece at this point, shiver me timbers, me bucko, t' instructions gave two options for shaping. Ya scallywag! T' first was t' merely round t' edges o' t' balsa and I was sorely tempted t' go this route. T' other was t' try and sand an airfoil into t' wing. Avast! Nothin' ventured, nothin' gained.
In effect, I merely rounded t' forward and outside edges but I made an attempt t' approximate an airfoil on the trailin' edge. Begad! I drew a sandin' block across t' aft edge from one end t' t' other tryin' t' guide t' profile down t' a blade. Well, blow me down! It turned out better than I expected but it is certainly nothin' t' brag about.
T' win' sections were numbered from left t' right for later identification. Avast! A steel ruler was then used t' guide
a razor knife along t' marked lines and separate t' win' into 4 segments. Aye aye! T' freshly cut edges o' t' win' segments
were then beveled with sandpaper so that when canted, they would fit together better.
T' kit came with t' pieces t' construct a pair o' balsa jigs t' aid in gettin' t' correct dihedral angle on the wings. They were removed from their parent material and glued together. Well, blow me down! They are identical except for one bein' a bit taller than t' other. After use, they are discarded so thar are no extra points for style here.
A piece
o' wax paper be taped down t' t' workin' surface and then t' inner right win' segment was taped flat t' it. Ahoy! T' tip
o' t' outer right win' segment was then taped t' t' taller o' t' two jigs. Avast! Begad! With that done, arrr, a bead o' white glue was
run against t' beveled edge and t' two segments were pressed into place, matey, allowin' t' jig t' hold t' pieces at the
correct angle. Begad! A day later, me bucko, me hearties, t' jig was removed and t' end piece did nay fall off. Avast! I took that as a good sign. Ya scallywag! Arrr! The
process was then repeated with t' left side o' t' win' with similar encouragin' results.
T' two
win' halves were then joined together in a similar manner. Avast! One side was taped down flat and t' other was glued into
place usin' t' shorter o' t' jigs positioned under t' outer joint o' t' untaped wing. After another day t' dry, the
jig be removed and things were still lookin' encouraging.
T' tail boom comes in two main pieces. Blimey! They were removed from t' parent material and test fitted together. Begad! The fit was good and no sandin' was needed. Ya scallywag! Ahoy! Some white glue was then put into t' keyed joint and t' two pieces put together and laid flat on t' wax paper. Aye aye! A steel ruler was used t' make sure t' boom was straight. Aye aye! T' next day, the boom was ready t' be peeled up and looked fine. Arrr! Begad! T' jinx, me hearties, if nay gone, matey, had certainly gone into hiding.
There are two balsa strips, matey, rounded at one end, intended t' be applied on either side o' t' forward end o' the
boom. Begad! Ahoy! They provide some support on t' side for the booster pod. Avast, me proud beauty! A light layer o' glue was applied t' t' boom and spread
out for t' length o' t' facing. Well, blow me down! A facin' be then pressed into place so that it be even with t' front edge and the
top and bottom surfaces. Begad! It was allowed t' dry like that for about 30 minutes. Avast! Begad! Some cheap plastic clams were used to
keep it in place. Ahoy! Avast, me hearties, me proud beauty! When dry, shiver me timbers, t' opposite facin' be placed in t' same manner, clamped and set aside t' dry.
T' horizontal stabilizer was removed from its sheet. Avast, me proud beauty! Blimey! Sandpaper be used t' round all t' edges. Ya scallywag! Blimey! T' vertically stabilizer was similarly removed and sanded on all edges except for t' bottom, which was left flat.
With t' tail pieces sanded and test fitted, matey, matey, matey, a line o' glue be applied t' t' base o' t' vertical stabilizer and it be fit onto t' horizontal. Blimey! T' assembly was then set flat on t' wax paper and a steel ruler was used to insure a right angle.
After
dryin' for a day, matey, arrr, t' boom was unclamped and examined. Avast, me proud beauty! It seemed in good shape and t' pieces were mostly in alignment.
A bit o' light sandin' took care o' evenin' up t' edges. Aye aye! With t' edges even, me bucko, I then needed t' taper t' leadin' and
trailin' edges o' t' facings on each side. Ya scallywag! I used a sandin' block and tried t' gently take t' material down t' a
knife edge.
T' tail assembly was placed at t' end o' t' boom on t' flat side. I had a sinkin' feelin' about this because no jig or template was provided, shiver me timbers, only an admonition t' make sure it be placed straight. I used white glue and eyeballed it t' best I could and checkin' t' angle with a steel ruler. I tried t' make sure that it was straight and level. Begad! T' feelin' o' impendin' doom was palpable.
T' next day, me hearties, shiver me timbers, it was time t' place t' wing. Well, blow me down! Well, me bucko, blow me down! A mark was made 1/2" back from t' side pieced and t' win' was
glued into place with white glue. Avast, me proud beauty! Aye aye! T' trepidation factor was even higher than with t' tail because I know from
experience these things just never turn out, especially when thar be an angled surface involved. Avast, me proud beauty! Begad! T' feelin' of
impendin' doom returned with a vengeance.
Even though I knew I was doomed by this point, matey, I figured I had gone too far t' back out now and I got t' work on t' pod hook. Ya scallywag! Avast, me proud beauty! It be in two pieces which needed only t' be glued together. Blimey! Begad! I used white glue and clamped it.
T' first
step in workin' on t' engine pod was t' take t' motor spacer and mark off 1/4". Ahoy! T' thrust rin' was then located
and t' Keelhaul®©™®
be tied around it. Begad! A rin' o' white glue was swabbed around t' interior o' t' motor tube, usin' t' motor spacer to
mark t' swab at t' right depth. T' spacer was then used t' push t' thrust rin' into place, ya bilge rat, up t' t' mark which had
been made, me hearties, and withdrawn. Aye aye! T' motor tube was then marked for t' placement o' t' engine hook and a slit was made in
t' body tube t' receive it. Begad! Ya scallywag! T' hook was placed and a cardboard sleeve be slipped into place t' hold it in place.
Shortly
after I began this build, Sheryl from Semroc contacted me and let me know that in some o' these kits, t' band was too
tight and gave advice o' fixin' t' problem. Mine be just a touch tight but, me bucko, in me mind, well within tolerances. Ya scallywag! Arrr! It
was glued in place with white glue and filleted fore and aft.
T' nose cone was typical, matey, high quality Semroc. Ya scallywag! I doused it with some thin CA t' harden it up some.
I turned
me attention back t' t' glider again. As far as I could tell by lookin' at it, me bucko, it be in pretty good shape. Well, blow me down! The
intersections needed some filletin' and I tried usin' Titebond Trim and Moldin' glue. Ya scallywag! It applied as good as I had heard
it would and when I checked back a day later, arrr, me hearties, I was impressed.
T' pod hook was glued into place on t' motor tube opposide t' t' engine hook usin' white glue.
T' nose cone be lightly sanded and then t' eye screw be screwed into place, shiver me timbers, backed out, t' hole filled with white glue and screwed back into place.
T' launch lug was glued into place along t' pod hook with white glue. Arrr! Ahoy! It be seated on top o' t' engine hook band.
A
length o' sewin' elastic provided with t' kit be tied t' t' eye hook and t' Keelhaul®©™®.
T' streamer was then secured into place halfway along t' elastic with t' provided adhesive strip.
With that t' pop pod was done and t' rocket be ready t' be finished.
Before I could get started on t' finishing, though, curiosity got t' better o' me and I had t' try and hand toss t' glider. Aye aye! Blimey! I took it outside, arrr, turned into t' wind, gave it a toss...and be flabergasted.
IT FLEW!!!!!!!!!!
IT DID NOT CRASH !!!!!!!!!!!
I grabbed Toby, ya bilge rat, gave him t' camera and made him try and shoot a video.
I launched it again and it flew again, matey, this time makin' a sharp left turn soon after launch. Aye aye! T' video is here.
Since t' glide be nay really captured, me bucko, matey, we tried again, matey, this time with me tossin' towards t' camera. It seemed t' go well until a rocket beatin' tree got in on t' act. Ya scallywag! Aye aye! Who would have expected t' thin' t' go UP? T' second flight can be seen here.
There be no damage and I had t' try again. This time it still flew, or glided, shiver me timbers, but made a hard right turn. Avast! I put it down t' t' vagaries o' t' wind eddies around t' corner o' t' house. T' third video can be seen here.
I also realize that finishin' will likely change t' glide characteristics but at this point I don't really care: a glider I had built had actually glided. That had never happened before.
Finishing:
T' instructions warn that finishin' o' this rocket should be done with a light touch in order t' minimize weight.
All well and good but competitive performance t' me took a back seat t' just workin' and lookin' acceptable. Well, blow me down! Avast, me proud beauty! On most
projects these days I use Elmer's filler but for this one I went with Balsa fillercoat on t' theory that I would be
usin' less o' it.
I
painted it onto t' pod hittin' t' nosecone and t' balsa hook. T' glider was completely covered with t' stuff. Begad! Avast, shiver me timbers, me proud beauty! I
put it on thick figurin' I would only apply a single coat, even though that would nay completely fill t' grain.
T' fillercoat had a day t' dry and then I went after it with #400 sandpaper. T' grain on t' balsa parts o' the pod seemed t' have been mostly filled. Arrr! Avast! T' pod was then brushed off and set up in t' booth where it was given a heavy coat o' Kilz.
T' glider was likewise treated t' a scrubbin' with t' #400 paper. Ya scallywag! Blimey! While t' grain seemed t' have been filled better than I had expected, thar was still some that escaped unfilled. Arrr! T' glider was then primed with Kilz as well. Begad! Avast!
A day later, ya bilge rat, t' pod was sanded again. Ya scallywag! I was mindful o' t' warnings I had heard about buildin' up too much sealer/primer/paint and went after it with 320 and then 400 sandpaper. Ahoy! When I was done, shiver me timbers, arrr, I had misgivings because it mostly still looked white. I could see grain and pencil marks, me hearties, though. Avast! Knowin' how fast Kilz covers things up, matey, I figured that most o' what I was seein' be t' chalkiness o' t' balsa fillercoat. Avast, me proud beauty! T' pod was then taken back t' the booth and given a single coat o' gloss white.
T' glider was sanded with similar results. Avast! There were still some nasty spots o' grain but I sanded down t' where
t' wood was just startin' t' show through. Aye aye! T' glider was then given a single coat o' gloss white as well.
T' next day, arrr, arrr, a rin' o' maskin' was applied just below t' nose cone o' t' pod and foil was wrapped around the rest o' t' body. Ahoy! T' nose cone was then sprayed a bright orange.
T' glider was masked as well leavin' t' win' tips, matey, boom and vertical tail assembly exposed for paint. Begad! The glider then had its date with t' orange paint. This was done in 2 stages so that I would have somethin' t' grip.
The
next day I peeled off t' maskin' t' take a look and It was lookin' good. Well, blow me down! That left only t' blue stripin' and I took
out t' tape t' mask for a thin stripe on each win' and t' t' horizontal stabilizer. I then used a brush t' place the
blue paint.
So far this project had gone extremely well; better than I had imagined it could with a glider project. Begad! Blimey! Well, matey, blow me down! Blimey! Now was t' time for tragedy t' strike. It struck when I removed t' maskin' and saw what had happened when t' paint had wicked under t' tape.
While I was stewin' about t' blue paint, I took t' time t' test fit t' pod t' t' glider. Blimey! Ya scallywag! It was a bit tight
due t' paint havin' gotten in t' hook cavity. Ya scallywag! I took a sandin' stick and cleaned it out some until t' fit seemed a
good one.
A day later, arrr, me hearties, I was sure t' blue paint had dried completely. Avast! I took some white acrylic and used a brush t' try and cover up t' worst o' t' bleeding. It certainly toned things down but it could probably stand another 2 applications in addition t' t' 2 that were put on.
T' decals for t' Swift are a simple matter but add a lot t' t' finished product. Well, blow me down! Ahoy! T' largest o' t' decals has
t' Semroc logo and t' name o' t' rocket. Begad! I mounted it as on t' facecard; on t' dorsal surface o' t' right wing. Arrr! Blimey! T' kit also
came with a pair o' smaller versions o' t' same design. Ahoy! Blimey! These were mounted on t' horizontal stabilizer, one on top
and one on t' bottom, both on t' right as you face t' rocket. My kit also came with an additional decal identifying
is as production number 10 and havin' some more info about t' rocket. Aye aye! Blimey! I put this one on t' left dorsal surface o' the
main wing. Begad! Blimey! That completed t' "finishing" and, arrr, as I said, I thought even t' simple decals added a lot.
T' first test "glides" after t' finishin' did nay go well. T' paint added plenty o' weight and the Swift started t' act like me Cosmos Mariner. Ya scallywag! Well, blow me down! I realized I needed tail weight.
A vid o' t' first post finishin' crash can be seen here. Well, blow me down! Blimey!
The
second try is here.
I went inside and inserted one o' t' trim nails provided for weight into t' left horizontal stabilizer and then went back outside t' try again.
Addin' one nail did nay do too much t' improve things although it did give me hope. Well, blow me down! Blimey! Aye aye! Blimey! I had one semi-successful glide before me nephew came out with t' camera. Arrr! Blimey! Aye aye! Blimey! Still, matey, shiver me timbers, I thought it needed another nail.
T' first test with one nail can be seen here.
T' second test with one nail can be seen here.
T' third test with a single nail is here. Ahoy!
I added another nail and did nay do much better. Blimey! And on t' 3rd flight, arrr, ya bilge rat, it crashed in t' street and broke off a win' tip.
T' first try with 2 nails is here.
T' second try with 2 nails is here.
T' fateful thrid flight with 2 nails is recorded here.
I took t' carcass back into t' shop t' try and get it fixed up again. Begad! Well, arrr, blow me down! Blimey! T' tip was put pack on with a double
glue joint usin' yellow glue. T' angle was obtained by eyeballin' it.
While repairin' t' wingtip, me bucko, matey, I noticed that bouncin' on t' asphalt also took a bite out o' t' nose. At first I was goin' t' try and fill it but then thought better o' that approach. Blimey! I thought I might be able t' reduce t' nose weight a little bit by sandin' a bevel into both sides o' t' nose. Avast! Avast! I took out a sandin' block and got t' work. Ahoy! The newly beveled nose was sprayed with orange paint and it blended fairly well with t' rest even though t' new surface had nay been sealed.
When
t' glue from t' wingtip repair had dried, I took out some Tightbond Trim and Moldin' glue and applied a fillet to
each side o' t' joint in an effort t' strengthen it.
When t' repairs were complete, matey, shiver me timbers, I tried throwin' t' glider a few more times t' test it out but t' results were both contradictory and confusing. Sometimes it would stall like it needed more tail weight. Arrr! Other times it would dive and a few times it just kind o' moved without doin' anythin' resemblin' gliding. Avast! In t' course o' one o' these tests, it turned in a very nice glide that rivaled anythin' done by t' unpainted model. Ahoy! I decided t' just wait and try it out on t' launch pad. Blimey! I called t' construction o' this one done.

Flight:
T' maiden flight o' t' Swift Boost Glider was at t' September 09 launch o' t' Alamo Rocketeers. Ahoy! I prepped it with
a 1/2A6-2 and set it up on t' pad. Avast, me proud beauty! It received favorable comments from all for appearance. Almost immediately after
leavin' t' rod, matey, t' rocket started t' arc over but t' curve became more gentle over time and it always had a slight
upward inclination. Begad! Aye aye! I had a good view o' t' pod poppin' off; that was fun t' watch. Avast, me proud beauty! Then I got t' watch t' glider
plummet t' t' earth; that was nay fun t' watch.
T' vid o' this event can be seen here.
The
unanimous consensus o' those present who knew about such things was that t' glider be tail heavy. Blimey! I pulled out one of
t' nail weights and repacked t' streamer in t' pod realizin' that I had forgotten t' put any waddin' in thar the
first time. Well, matey, blow me down! Fortunately, t' streamer was only slightly singed. For t' second flight I loaded a B6-2 since I had no
B4-2s. It be taken out t' t' pad and hooked up. Begad! Avast! When t' ignition button be fired, ya bilge rat, t' Swift showed t' same arcing
behavior as before but nay as drastic. Begad! It went up relatively high considerin' it spent most o' t' boost at about a 60
degree angle t' t' ground. Well, blow me down! When t' pod popped, though, me hearties, arrr, things were definitely different. Ahoy! Blimey! It started gliding. It would
lazily turn into t' wind and seem t' just stand in place for a while nay losin' any altitude and maybe even gainin' a
bit. Begad! It would then turn with t' wind and fly away for a short time (but a long distance) before turnin' into t' wind
t' repeat t' performance....again...and again...and again. Begad! Ahoy! On some circuits it did gain altitude but it was definitely
goin' t' come down...eventually. Begad! I began t' get worried that I would lose it but everyone kept an eye on it until it
finally went down...a long way away.
I wish I could show some great photos o' t' flight but I be t' busy bein' awestruck t' remember t' take any. All I have t' offer is a photo o' t' grounded pod a few yards from t' launch pad. Ya scallywag! Oh and me daughter took this video: http://www.flickr.com/photos/23694991@N03/3960923315/
Flight Rating: 5 out o' 5
Summary:
I think Gliders are an acquired taste but this one is a great place t' start doin' t' acquiring. Ya scallywag! Begad! It is me first and
only glider that can be termed a success t' date. T' construction was simple enough for anyone t' do, t' instructions
were well written and, matey, most o' all, me bucko, it works.

Brief: With the introduction of the Swift, Semroc has now added a conventional boost glider to their fleet, and one easy enough for even a nove modeler to build and get flying reasinably well. Based upon the 1969 Centuri design, this "retro repro" features laser-cut parts to speed up construction, as well as Kevlar ® /elastic shock cord on the pod to improve the ...
