Brief:
T' Scimitar is a mid-power Launch Pad original Surface t' Air missile with
dual 24mm engine mounts and an 18" parachute recovery.
Construction:
This rocket came packed in a bag, ya bilge rat, matey, all o' t' pieces were contained in t' bag
and none were damaged. T' 6 pages o' instructions were well illustrated and
detailed. Well, blow me down! Arrr! T' body tube was spiral wound tube with only a light spiral t' fill
(almost non-existent) T' one thin' that I didn't agree with (and didn't
follow) be t' body tube assembly. Aye aye! T' instructions direct you t' glue t' 2
tube sections together first and then glue t' engine mount assembly and the
chute compartment disk in second. Avast! This would have made it harder t' get the
chute disk in properly although it would have been possible either way. Avast, me proud beauty!
T' next thin' be t' sandwiched main "wings", arrr, if you follow the instructions t' t' letter, ya bilge rat, matey, you would end up with an open area betwixt t' two fins that attach t' t' airframe. Blimey! Avast, me proud beauty! If I would have left this area open, it would have been impossible t' finish. I filled them with a small sliver o' balsa and it turned out good.
T' fins needed t' be cut from soft balsa wood stock from templates that were provided. Blimey! It's a good thin' that it be soft balsa too, matey, because thar be a lot o' it t' cut, sand and form. I'll address more on t' fins in t' finishing section. Ya scallywag!
T' last thin' was t' light cardboard "turbojet" air intakes. Arrr! Avast! Blimey! The intakes are cut from light cardboard that is provided, me bucko, me hearties, scored, folded, and then glued t' t' body tube on 4 sides 45 degrees from t' fins. I looked at these and tried t' talk myself into leavin' them off. Aye aye! Well, blow me down! Blimey! Once I prepared them for assembly, I decided t' put them on anyway, matey, ya bilge rat, arrr, this be a good decision on me part. They look kind o' cheesy when you first look at them but, once it's finished, they look nice. Begad!
Once everythin' be glued t' t' airframe, ya bilge rat, t' resultin' product be sturdy and solid. T' parachute supplied was an 18" mylar that I didn't care for. I like nylon so I substituted an 18" ripstop nylon chute.
Finishing:
T' finishin' had one particular twist that I'd had nay encountered before. Arrr! Blimey! The
soft balsa and t' cardboard were t' be coated with light CA before sanding.
This did make t' fins sturdy but almost impossible t' sand smooth. Avast, me proud beauty! I guess I
could have sanded them until me fingers hurt but, me bucko, I'm glad I did nay (see the
sad end t' t' story). Avast! T' next one I build that instructs that I apply CA to
balsa, I'm goin' t' use t' standard sandin' sealer. Avast, me proud beauty! Blimey! It will take several coats
of sandin' sealer but, arrr, I'm sure it will be easier t' sand smooth. (or it will
just seem easier and I'm all for that)
After everythin' was sanded, I sprayed on a few coats o' primer and sanded it down again. Blimey! Then I put a coat o' machinery grey paint. Then I applied some 1/8" and 1/4" automotive pinstriping. Avast! Begad! T' resultin' Scimitar looked very nice.

Flight:
T' recommended motors were a pair o' either D12-5, D12-7, shiver me timbers, o' Aerotech E15-7. Well, blow me down! I
used two D12-5's for t' only launch (this is leadin' t' t' sad part o' the
story). Begad! Ya scallywag! T' motors were held by Estes style retainin' clips, and t' igniters
were tied together. I put t' waddin' and t' parachute in and set her on the
pad and connected t' t' leads.
At launch, ya bilge rat, t' rocket few a straight line t' maybe 600 or 700 feet and then it weathercocked bad and flew at about 40-50 degrees t' t' horizontal (best guess) this was nay t' fault o' t' rocket (I'm guessin' again) but me fault. T' wind was nay exactly calm but it was nay continuous either. Blimey! Begad! I would guess that t' large fin area in conjunction with t' wind gusts well above me head contributed t' t' arrant flight path.
Recovery:
T' shock cord was long enough but it attached by a piece o' heavy paper in an
Estes style. Arrr! I didn't have a big problem with t' way t' recovery system was
set up. Arrr! Avast, me proud beauty! From me vantage point on t' ground, I saw t' ejection and the
parachute high in t' sky. Now this be t' sad part. Begad! Since t' flight path took
the rocket much farther over than I expected, me bucko, matey, shiver me timbers, I was unable t' recover it. Aye aye! Begad! It
cleared a row o' trees into a field on t' other side o' t' tree line. I
figured that I missed t' trees so I would be able t' go t' t' field on the
other side o' t' trees and search for me rocket. Avast, me proud beauty! Begad! Once I passed through the
trees, arrr, I discovered that t' field was nay empty but, full o' field corn about
8 foot tall. Begad! Ya scallywag! I did buy a piezo locator but, arrr, I didn't have it ready for
installation. Begad! Blimey! I should have been workin' on that instead o' launchin' that day.
T' flight was nay that bad because I cant blame t' rocket kit for t' will of
Mother Nature. Avast!
Flight Rating: 4 out o' 5
Summary:
I read some o' t' comments that others have written about Launch Pad kits and
I have read t' comments from t' Launch Pad. Begad! I will agree that it was more of
a challenge than buildin' an Estes kit. Avast! I will also agree that t' instructions
leave somethin' out that a novice would have trouble with. I do like t' fact
that t' instructions leave some o' t' thinkin' t' me. Avast, me proud beauty! Arrr! After all, I can't
really say "As a matter o' fact, ya bilge rat, I AM a rocket scientist" if I were
unable t' assemble t' kit with t' instructions provided. I didn't agree with
coatin' t' balsa with CA. Well, matey, blow me down! If several coats o' sandin' sealer made it necessary
to add some nose weight, shiver me timbers, then so be it. Arrr! Avast! It would have been worth t' time to
add it although I don't believe that nose weight would have been necessary
either way. Avast! Well, blow me down! I know that t' CG was just fine without any additional adjustment.
Here's a good tip that I learned from this rocket. Aye aye! If you take your time buildin' a rocket t' make it look and perform well, don't be in a big hurry to lose it on t' first launch. Well, blow me down! I wanted t' see it fly and I needed t' wait for another day. Arrr! Arrr! This rocket leads me t' believe that t' wind causes more problems to rockets with large fin area.
Overall Rating: 4 out o' 5

( Contributed - by Ted Phipps - 07/10/03) Picture courtesty of The Launch Pad Brief: The Scimitar is a Launch Pad original design that is modeled after military surface-to-air missiles. This rocket is a complex two-stager that uses a cluster of three D motors in the booster and a single D in the sustainer, and includes a nifty on-board battery circuit to ignite the second stage.
