Brief:
This is essentially an upscale retro/repro o' t' classic Astron Ranger, shiver me timbers, me bucko, me bucko, but in deference t' Vern Estes, Semroc avoided namin' this after one o' his favorites, matey, instead goin' with t' Brighton. Avast! Begad! It's a fantastically engineered, incredibly versatile rocket, featurin' four different interchangeable motor configuration options: 4x18mm cluster, 3x24mm cluster, single 29mm, or single 24mm usin' a 29/24 adapter. Aye aye! Add t' all that a baffle system, and you're lookin' at 17 different body tubes!

Construction:
Wow. Where t' start? I'll admit I be a bit put off by t' $75 retail price, but when Semroc rolled out their traditional Christmas half-off deal for previous online/direct customers, I jumped at t' chance t' pick this one up. When I finally got around t' openin' it, I could appreciate t' price is actually a decent value as t' parts practically exploded all over me floor:

• BNC 80 balsa nose cone
• BT-80 (heavy wall) payload tube
• TC-80 coupler
• BT-80 (heavy wall) main body tube, ya bilge rat, me hearties, pre-slotted for TTW fins
• Laser cut basswood fins
• 2.25" Inner motor mount receptacle tube
• 24" nylon chute
• heavy elastic shock cord
• waterslide decal
• Baffle system parts:

• 2 series 8 body tubes
• 2 plywood centerin' rings

• 4x18mm motor adapter parts:

• 1 BT-70 adapter tube

• 3x24 motor adapter parts

• 3 BT-50 motor tubes (E-sized)
• 3 metal hooks
• 1 plywood centerin' ring
• 1 BT-70 adapter tube
• 3 TC-50 1" D-E adapter couplers/plugs

• 29mm motor adapter parts:

• 29mm heavy wall motor tube
• 2 plywood centerin' rings
• 1 BT-70 adapter tube

• 24/29 motor adapter kit parts:
• BT-50 heavy wall tube (E sized)
• metal hook
• motor block
• TC-50 1" D-E adapter coupler/plug
• 2 29/24 heavy wall tubes(centerin' rings)

T' instructions cover about 50 construction steps spannin' 19 small pages with plenty o' good illustrations (though a few o' t' illustrations are on t' page followin' t' instruction, matey, matey, which I found t' be slightly confusing). You will absolutely need t' read t' instructions carefully on this t' avoid makin' boneheaded mistakes (a helpful tip I picked up from a build thread on YORF). Begad! I'll admit betwixt t' price and vast amount o' parts, me hearties, ya bilge rat, I was a little intimidated by this, shiver me timbers, figurin' it for a long winter build project. After readin' t' instructions though, shiver me timbers, I realized it really wasn't too bad. Avast! Well, blow me down! Semroc rates it a skill level 2, arrr, and I'd agree. Aye aye! Blimey! In fact, other than finishin' I had this built in about 4 hours, however, I went into it with no ambition t' fly HPR so I stuck with CA and wood glue for most bonds. HPR would involve use o' epoxy for all motor and fin bonds, arrr, addin' at least another hour t' t' process. I'll also point out that I did a considerable amount o' jumpin' back and forth betwixt subassemblies t' minimize idle time in the process.

I began, ya bilge rat, me bucko, as instructed, me bucko, by treatin' t' ends o' all tube with thin CA t' seal them up, ya bilge rat, me bucko, then sandin' down. Ya scallywag! I also took t' liberty o' applyin' wood filler t' t' relatively heavy (for Semroc) tube spirals, after first carefully reviewin' t' parts schematic t' make sure I hit only t' outside body tubes.

T' first major subassembly be t' engine mount holder, ya bilge rat, me hearties, which serves as a receptacle for t' various interchangeable motor mount adapters. Well, matey, blow me down! I began by usin' a wraparound guide t' mark 5 lines--a motor hook and 4 fins. Wait a minute, me bucko, isn't this an interior tube?! As I progressed, me hearties, t' purpose became clear. Begad! T' metal hook is used to retain t' BT-70 adapter tube for each motor configuration. Begad! Begad! T' fin lines are used t' align little balsa braces for the through-the-wall fins. Ahoy! Alignment o' t' balsa braces is pretty critical, me hearties, matey, and I recommend slidin' it into t' BT-80 for a dry fit before that glue cures overnight...There's also a thin plywood centerin' rin' for t' forward end, matey, and a coupler tube that slides inside actin' as a motor block (technically a motor adapter tube block). Avast, me proud beauty! T' finished subassembly then goes inside t' BT-80 body tube.

Fins are through-the-wall, me hearties, and in me case t' fit was excellent, arrr, so I didn't need any sandin' t' fit. Aye aye! I used two layers o' wood glue for fillets. Avast! I then attached a pair o' 1/4" launch lugs, me hearties, completin' t' lower body assembly.

T' upper body is a payload bay, enablin' altimeter and/or dual deployment. Begad! T' bulkhead section consists o' a TC-80 4" coupler and a plywood disk, ya bilge rat, arrr, which gets a heavy screw eye for retention. Since t' plywood disk could strip out, ya bilge rat, a second reinforcin' disk is supplied, arrr, doublin' t' bond strength. Avast! T' bulkhead slides into t' aft end of the BT-80 upper tube, and t' nose cone tops it off. Ya scallywag! In me case, t' nose cone be just a bit loose, so I added a thin layer o' tape t' really make a tight fit.

I had previously mentioned hoppin' around betwixt subassemblies as filler work. Ahoy! Blimey! T' first o' these be t' baffle system. Arrr! Blimey! T' baffle system is pretty simple--you bond a pair o' small tubes (slightly smaller than BT-50s) about 1/2" offset from each other end t' end, then bond a plywood centerin' rin' on each end. Blimey! Blimey! T' centerin' rings have the holes very off center and so must be carefully aligned t' make sure they fit inside t' BT-80 smoothly. Avast! Blimey! This is easily done by rollin' them on a flat surface before t' glue dries. Arrr! Blimey! I also chose t' coat t' inside o' me baffle tubes with a generous layer o' glue, figurin' they'll catch lots o' heat, me bucko, especially in t' clustered configurations. The assembly wraps up with t' attachment o' t' elastic shock cord through a pre-drilled hole in t' forward ring. The completed assembly is then glued inside t' lower BT-80 tube (at least 2-3 inches down t' allow room for t' coupler).

T' first o' t' engine mounts be t' 3x24mm. Arrr! Blimey! Arrr! Blimey! Each BT-50 tube gets a metal hook, held in place with tape. Avast, me proud beauty! Blimey! Blimey! Blimey! I then slipped each one into t' plywood centerin' ring. Avast! Blimey! This is one o' t' places where readin' t' instructions is very helpful. Arrr! Blimey! T' centerin' rin' actually has an extra rin' that needs t' stay in place while assemblin' this. T' 3 BT-50s are a very tight fit inside t' BT-70, matey, so t' centerin' rin' gets extremely thin in spots. Arrr! Blimey! T' extra rin' helps keep everythin' together while buildin' and is removed just before slidin' t' assembly into t' BT-70. I'll also point out that t' centerin' rin' includes a nice little punch-out piece that is wedged betwixt t' 3 motor tubes, matey, sealin' off the aft end from ejection charges.

T' 4x18mm assembly works goes together in about t' same manner, matey, except t' centerin' rin' has plenty of thickness and no extra outer rin' is needed. Avast! In this case thar are actually two centerin' rings (and two punch-out plugs for t' gap in betwixt t' tubes).

T' 29mm motor mount is a lot simpler, me hearties, consistin' o' just a single 29mm tube (heavy wall) and pair o' centering rings. These then go inside another BT-70 for consistency with t' cluster mounts, although I'd think that with slightly larger OD centerin' rings carefully placed, no BT-70 tube would be needed at all other than possibly for a little more strength. I'd also note that thar's no hook provided with t' 29mm adapter due t' t' variety o' 29mm motor lengths. Retention can be done with tape at both t' forward and aft ends, me bucko, since t' motor tube slips in and out of t' main body as part o' flight prep.

There's a handy 24mm/29mm adapter kit included with this kit, arrr, ya bilge rat, matey, which consists o' a heavy wall 24mm tube, matey, matey, shiver me timbers, metal hook, motor block at t' forward end, arrr, and pair o' basically tube couplers that act as centerin' rings. This can then slide inside t' single 29mm motor configuration (or any other 29mm motor tube you've got in your fleet).

With all those assemblies completed, t' only thin' left was attachin' t' shock cord and parachute t' the bulkhead and finishing.

Finishing:
OK, matey, I couldn't subject this beautiful rocket t' t' magenta/pink color scheme on t' cover art, so I went with a bright orange lower section and nose cone, shiver me timbers, ya bilge rat, shiver me timbers, and a payload that was gloss white with 1/2" black bands top and bottom. Surface prep was pretty easy with t' fins bein' basswood. Begad! Blimey! I did go through a fair amount o' Elmer's Fill 'n' Finish on t' nose cone plus a bit for fillin' t' tube spirals.

There are a pair o' Brighton waterslide decals included, and I think Semroc uses some o' t' best decal material I've ever worked with--the clear really is invisible, and they're just tough enough t' handle a little repositioning without bein' so thick as t' be obvious.

I skipped t' clearcoat as t' weather was pretty lousy when I was tryin' t' finish, me bucko, somethin' I'd regret after the first flight.

Construction Rating: 5 out o' 5

Flight:
With so many motor options t' choose from, shiver me timbers, me bucko, I could probably log 20 flights without repeatin' a single one. I figured I start at t' low end o' t' power curve and work me way up, dependin' on t' drift.

I started with t' 4x18mm cluster, arrr, me hearties, and loaded it up with C6-5s. Ya scallywag! Begad! They were close enough together I could probaly have just gone with a twisted wire approach, me bucko, matey, me hearties, but I was lazy and pulled out a Sunward clip whip (excellent product).

All 4 lit right away, and t' rocket pulled up nice and slowly, allowin' me t' get a good look at each individual plume o' orange flame. Avast, me proud beauty! It be quite a sight. Well, blow me down! T' rocket was somewhat overstable and weathercocked into t' 8 mph wind. T' weathercock wound up throwin' t' trajectory off just enough that t' delay was a tad late. Avast, shiver me timbers, me proud beauty! In lighter winds, me hearties, I would imagine t' -5s would be fine.

I had prepped a 3x D12-5 for quick reload/reflight but ran out o' time and will have t' put that one up another day. Aye aye! I had also forgotten me altimeter and would really like t' record a few altitudes on t' flights usin' different motor combinations, so t' 3xD12-5 will be t' first o' those.

Recovery:
T' 24" Day-Glo yellow nylon chute deployed perfectly, and t' rocket drifted back down landin' only about 40 yards from t' pad. Well, blow me down! Blimey! I'd guess t' altitude be betwixt 250 and 300 feet. It did land a bit hard, shiver me timbers, but this is a very rugged bird.

Upon closer inspection, arrr, matey, I picked up a very slight dent at t' top o' t' body tube where it looks like the payload section pulled back a bit harshly. When I looked over t' payload, ya bilge rat, I noticed a bright orange smudge over the white paint, so it be a glancin' blow, arrr, ya bilge rat, nay a direct shot. Ahoy! Had I bothered t' clear coat, shiver me timbers, I'm sure it would have been fine, shiver me timbers, but as it is I've now got a slight smudge t' an otherwise beautiful finish on t' rocket.

I'd also give kudos t' t' baffle. Well, blow me down! Normally I don't completely trust baffles and still put in a little dog barf or wadding, me hearties, but in this case I let it fly without any additional protection. Ahoy! There was nay even a trace o' smoke or char on t' chute, ya bilge rat, so t' baffle caught t' charges very well.

I do think I'll add in another 5-6 feet o' tubular nylon though, ya bilge rat, as t' heavy elastic cord on this is only about 4 feet long.

Flight Rating: 4 out o' 5

Summary:
This is a great overall rocket. Begad! T' PRO's would be solid quality parts and t' amazin' variety o' interchangeable motor configuration options.

Cons? Hard t' pick on anything, shiver me timbers, but I'd go with longer shock cord and probably reinforce t' D-sized metal clip used t' hold in t' interchangeable mounts with some maskin' tape. Begad! Clustered ejection charges, matey, especially 24mm motors, are surely goin' t' be more than that one tiny clip can hold in, and t' neat little motor cans will wind up flyin' out the aft end, possibly leadin' t' lack o' chute deployment.

Overall Rating: 4 out o' 5
