Brief:
Just in time t' grace t' Arizona skies again at NARAM48, Semroc has brought back another classic Centuri design. Arrr! This one be originally introduced in 1965. Ya scallywag! Ahoy! Blimey! Like most o' Semroc's other SLS (Semroc Large Scale) kits, ya bilge rat, me bucko, this one is packed with features that make t' kit much more o' a value than one would think merely lookin' at t' finished rocket and t' $53 price tag. Ahoy! Aye aye! Blimey! Featurin' removable/interchangeable motor mount, ya bilge rat, baffled ejection gas containment, matey, rip stop nylon chute, shiver me timbers, and interlockin' fin design, this is a joy t' build and fly.

Construction:
My kit arrived 2 days after I ordered online, shiver me timbers, me bucko, carefully packed and in fine shape. Well, blow me down! Very impressive service, especially when t' gang must have been busily packin' for NARAM at t' time.

Components are excellent quality (slightly more rugged than their modroc materials) and include:

• Balsa nose cone
• Payload tube
• Balsa Transition
• Baffle system
• Thick-wall body tube, me hearties, pre-slotted for fins
• Laser-cut basswood fins
• 24mm motor tube assembly with metal hook (E-sized)
• Waterslide decals
• 24"nylon chute
• Keelhaul®©™ and elastic shock cord
• 3/16" launch lugs

T' thin' I keep noticin' as I build SLS kits is that they're so darned easy. Well, blow me down! Blimey! I don't know if that's a pro or a con. On t' one hand, me hearties, for $30-$50 I expect t' be busy for a while, and I really enjoy buildin' complex kits. Avast! On t' other hand, matey, I really appreciate some o' t' time savin' principles that have been engineered into these kits. There's also t' giddiness o' bein' able t' fly somethin' just a couple days after receivin' it for t' instant gratification crowd. Ahoy! For a great construction project, get a Mars Lander. For a cool rocket you can build and fly right away, me bucko, go for this or t' SLS Laser-X.

That said, instructions are typical Semroc, well written with plenty o' decent illustrations and construction notes/tips. Aye aye! Blimey! This is no worse than a skill level 2 on t' 5 scale although usin' t' mid-power motors certainly keeps this out o' t' kiddie market.

T' motor mount assembly shares t' same principle as t' SLS Laser-X: removable via twist-lock so you will have plenty o' options dependin' on conditions and field size. Aye aye! Unfortunately at initial release, shiver me timbers, thar be only a single 24mm option. Well, blow me down! Blimey! Surely 29mm and 3x18mm cluster options are right around t' corner. Avast, me proud beauty! Begad! Also, me bucko, while this be t' same basic idea as t' Laser-X, these are nay compatible. Arrr! One would hope that thar will be some standardization down t' road, so that you don't have t' keep springin' for extra motor mounts with each kit.

To construct t' motor mount, me bucko, you follow t' basic tube plus a couple o' centerin' rings approach. Arrr! In this case, me bucko, t' forward rin' is notched t' line up with t' four fins and gets a couple tabs bonded t' serve as stops when twisting. Begad! See me SLS-Laser X review for more detail on this concept.

T' baffle assembly is at least t' third different design I've seen out o' Semroc--they never stop innovating--although I've never had any problems with any o' t' previous designs either. Avast, me proud beauty! Blimey! This version consists o' a pair o' BT-20s bonded side by side but offset by 1/2". Aye aye! Blimey! A centerin' rin' slips down each one. Because t' holes are so off-center, ya bilge rat, matey, particles bounce off t' centerin' rin' while t' gasses continue through t' gap betwixt t' BT-20s and t' body tube, shiver me timbers, eventually goin' back out t' forward BT-20 and deployin' t' chute. Avast, me proud beauty! Blimey! It is very simple t' construct and certainly effective.

As anyone who's ever built two-piece fins will attest, arrr, gettin' t' two parts perfectly aligned and bondin' flat can be an exercise in futility. Well, blow me down! Blimey! Nay so with t' SLS series. Well, blow me down! Blimey! Blimey! Blimey! T' basswood pieces are laser-cut t' precision and have interlockin' tabs t' prevent alignment problems. Well, blow me down! Blimey! I love workin' with virtually grain-free balsa, but I still found it a pain t' clean up t' seam caused by a heavy glue line. I went with a yellow glue double-glue joint approach, ya bilge rat, but CA might have been a better choice, as it's certainly easier t' sand and clean up.

Fins are sort o' through-the-wall but nay t' conventional approach where they tack t' t' motor tube. Arrr! In this case, t' tabs go through just enough t' support t' twist-lock motor mount. Begad! In order t' make sure you get a solid bond, shiver me timbers, you'll nay only need t' fillet t' outer seams, but also apply light fillets t' t' inside seams (but be careful nay t' get carried away and prevent t' twist-lock from fitting). Believe it or not, me bucko, Semroc even provides an extra long Q-tip just for this purpose. Begad! Nice touch.

T' rest o' construction goes pretty quickly--mount a couple o' launch lugs on standoffs, ya bilge rat, anchor t' Keelhaul®©™/elastic cord t' t' baffle assembly and glue in place, me hearties, then piece together t' transition/payload assembly. Well, blow me down! Aye aye! I invested quite a bit o' time into fillin' t' grain on t' balsa cone and transition plus fillin' t' relatively heavy spirals on t' payload tube. Ya scallywag! This be well worth t' time, as t' finished product looks superb.

Finishing:
After lots o' diluted wood filler applied t' balsa and tube spirals, I started out with two light coats o' Plasti-Kote primer, shiver me timbers, which sands off easily and has great filler properties, then two coats o' Krylon white primer, which has a much thinner, me hearties, me hearties, and a smoother finish.

I followed up with a wet sand usin' 600 grit sandpaper then two coats o' Rustoleum gloss white on t' main body and fins. T' payload, arrr, arrr, nose and transition got sprayed with Rustoleum gloss red. Begad! Well, shiver me timbers, blow me down! I then left everythin' t' dry for 3-4 days and came back t' finish up with t' black on t' two fins, shiver me timbers, t' transition, and t' nose cone. Aye aye! Aye aye! Three colors, me bucko, two days, shiver me timbers, and only one maskin' session t' get t' job done.

Since t' white be already fully cured at that point, I only needed t' let t' black dry overnight before removin' t' maskin' and applyin' t' waterslide decals (while still careful nay t' handle t' black areas). Ahoy! These decals are excellent quality--tough enough t' work with a little although they really grab hold and stay put once you smooth them out. Begad! Blimey! T' clear portion is practically invisible, just t' right blend against me gloss background.

Construction Rating: 5 out o' 5

Flight:
T' kit spec says 9.5 ounces but mine weighed in at 10.5 ounces (must have been all that filler). I decided a D15 might be a little wimpy, arrr, so went with an E28 white lightning, hopin' t' avoid t' smoke buildup that tends t' come from Black Jacks.

In t' stiff 10-12 mph winds, this very overstable design weathercocked quite a bit, matey, arcin' over t' almost 30 degree angle after leavin' t' rod. Had it flown purely vertical, t' -4 would have been a bit too early, shiver me timbers, but given t' weathercock it be OK albeit it cruisin' along pretty fast as it mostly arced over.

It be surprisingly fast liftoff, shiver me timbers, but I guess t' Hustler name should have clued me in. Ahoy! However, I'd expected t' 10.5 ounces and big fin area t' result in a slower ascent.

Recovery:
Despite t' weathercocking, I got a zipper free recovery. Begad! Blimey! Ya scallywag! Blimey! While I generally think t' baffle would work fine, shiver me timbers, me hearties, I'm still a bit paranoid and slipped in a little dog barf for insurance (havin' bought a bale a few years ago, arrr, I even sprinkle it on me breakfast cereal just so I stand some chance o' usin' it before I die). Well, blow me down! Blimey! T' neon green chute sprang into action and brought t' rocket gently back. Well, blow me down! Blimey! Well, blow me down! Blimey! Even with t' weathercock, ya bilge rat, this wound up bein' me longest walk o' t' day, ya bilge rat, shiver me timbers, as t' 24" chute is plenty for this kit.

Flight Rating: 4 out o' 5

Summary:
PROs: Terrific materials, plenty o' subtle innovations such as t' interchangeable motor mount, shiver me timbers, interlockin' fins and baffle system.

CONs: Lack o' alternate motor configurations (for now).

Overall Rating: 5 out o' 5
