Brief:
Very affordably priced single stage, arrr, 13mm minimum diameter kit. Arrr! Very high performance--it will zip up t' incredible altitudes almost instantly. Well, blow me down! This is actually a Semroc original, me bucko, nay one o' their retro/repro Centuri designs.

Construction:
T' kit came sealed in a plastic bag with a header card and included a serial number identifyin' its production number. Ahoy! Well, blow me down! Components were all very good quality and included:

• ST-5120 body tube (basically a BT-5)
• Balsa nose cone/screw eye
• Laser-cut balsa fins
• 1/8" launch lug
• Keelhaul®©™/elastic shock cord combo
• Crepe paper streamer
• Motor block
• Waterslide decals
• Motor casing, Q-tip glue applicator

Yes, matey, me hearties, this kit includes a motor casin' (actually just a plain cardboard tube) and a Q-tip for applyin' glue up inside t' body tube. Nay bad for a $5 kit and that makes this a very good project for Cub Scouts and school groups. Avast, me proud beauty! Cheap, easy, matey, me hearties, and includes t' little gadgets t' simplify construction that most o' us experienced builders take for granted. Ya scallywag! This kit is definitely somethin' that can be built in under an hour, plus paint/finish time. T' instructions were clear, have plenty o' good illustrations, arrr, shiver me timbers, and everythin' fit fine.

Bein' a minimum diameter kit, matey, thar's no motor mount assembly t' work on. Instead, arrr, you just glue a motor block inside t' body tube. Avast, me proud beauty! Even though I usually use scrap balsa for this, matey, ya bilge rat, I though it was neat that they included a Q-tip for this application. Blimey! Keep in mind though that before gluin' in t' motor block, you must first tie t' Keelhaul®©™ shock cord t' t' block. Avast! Avast! I really like t' Keelhaul®©™ but this looked a bit light (maybe 90#) and I'm curious how it will stand up t' repeated flights.

Fin preparation is pretty easy, since t' fins for this (and all Semroc kits) are laser cut. After a light sanding, they're ready t' bond t' t' body tube. Ahoy! There are 3 fins attached at t' standard 120-degree rotation. Arrr! Aye aye! Be sure t' apply a good fillet on these, as t' fins are tiny and thar be a lot o' stress when flyin' this on an A10.

T' nose cone is a standard balsa nose with screw eye anchor. Blimey! Ahoy! No additional nose weight is needed on this. Blimey! This be a very nice balsa cone. Avast, me proud beauty! Ahoy! Semroc really packs quality and value into their kits.

Construction wraps up with t' attachment o' t' crepe paper streamer. Begad! Blimey! It's a nice orange 1" wide streamer, ya bilge rat, although I think t' small tape disk/dot for attachment is pretty flimsy so I upgraded mine t' heavy maskin' tape at t' base.

Finishing:
T' instructions do a nice job o' detailin' out how t' properly seal balsa; suggestin' up t' 3 coats o' sandin' sealer. Begad! I cheated and went with a single diluted coat o' Elmer's Fill 'n' Finish, me bucko, which I sanded down with 240 grit sandpaper.

After sandin' down a coat o' gray primer (used mainly t' fill spirals), me hearties, I followed up with a white primer base, ya bilge rat, ya bilge rat, then two coats o' gloss white. Begad! Blimey! T' illustration on t' header card shows a yellow base. Avast! Ahoy! Blimey! I've never really had much luck with Krylon yellow and unless it's over pure white I wind up needin' a lot o' coats t' cover up basic pencil marks or base coats. Begad! Blimey! I found a can o' safety/dayglo yellow though and decided t' give it a shot. Avast, me proud beauty! Avast, me proud beauty! Blimey! It looked GREAT and only needed a couple o' coats. Well, shiver me timbers, blow me down! Blimey! T' bright yellow really stands out.

T' kit also includes a set o' water slide decals, shiver me timbers, which I think are an excellent addition t' this kit. Avast, me proud beauty! It would look fairly borin' otherwise, ya bilge rat, matey, but with t' decals it almost looks like a bee.

Construction Rating: 4 out o' 5

Flight:
First flight be on a fairly windy day, me hearties, matey, approachin' 8-10 mph. I went with a 1/2A3-4. Despite t' wind, this raced absolutely straight up and cooked t' easily 400 feet. Avast, me proud beauty! Ya scallywag! T' streamer rolled out right over apogee and everythin' came back in great shape.

I have since flown it in calmer winds on A3s and A10s, matey, ya bilge rat, both o' which take it out o' sight. Blimey! For full As, I recommend usin' trackin' powder t' make sure you can spot it. Avast! Tempera paint powder makes great trackin' powder as does crushed chalk (from a home supply store).

Recovery:
Perfect flights, me hearties, no problems whatsoever.

Flight Rating: 5 out o' 5

Summary:
I've built a bunch o' Semroc kits now and this one is one o' me favorites. Begad! It's a great value, me bucko, arrr, easy t' build, matey, and flies out o' sight on a $0.75 motor. Arrr! It doesn't get much better than that.

Overall Rating: 5 out o' 5
