Brief:
T' Brighton is an upscaled version o' t' Estes Ranger. T' kit features four different interchangeable motor mount
options: 4x18mm cluster, 3x24mm cluster, shiver me timbers, single 29mm, ya bilge rat, me hearties, or single 24mm usin' a 29/24 adapter. Ahoy! T' Brighton includes a
baffle system t' protect t' recovery parachute from t' ejection gases.
Construction:
Lots o' parts with this kit!
T' Semroc instructions are excellent and include excellent illustrations. T' first part o' t' construction involves t' motor mount, me hearties, and t' parts that make it interchangeable. Begad! Semroc provides a wrap for markin' t' fin lines, and motor mount hook. Arrr! Blimey! Be careful and make sure your lines are accurate so t' fins will align correctly. Aye aye! Dry fitting this assembly usin' t' BT is a must t' make sure everythin' works out correctly. Begad! T' fins are TTW and t' fit was excellent. Begad! Epoxy was used t' glue t' fins, and epoxy/microballoons be used t' create nice fillets. Blimey! T' included launch lugs are 1/4". Aye aye! T' upper body is basically a payload bay. Well, blow me down! Good place for your altimeter, arrr, experiments, shiver me timbers, or cargo. Ahoy! Nothin' unusual about t' construction in this area so I won't spend t' much time here. T' nose cone has no retention method other than a friction fit. This works, just be sure you have a secure fit.
T' baffle included in t' kit a very easy design t' build, yet effective. Aye aye! It uses t' offsettin' tube design that attaches t' centerin' rings. Avast, me proud beauty! This assembly is slid into t' lower body. Arrr! T' baffle also is also used t' attach the shock cord. Avast! I used a thin coat o' epoxy t' glue t' baffle into t' body tube. Arrr! If you like gluin' tubes t' various modular motor mounts are goin' t' be perfect for you. Ya scallywag! It takes a while t' get all o' t' adapters built, but once completed you can use any motor you have in stock.
Finishing:
Followin' me normal procedures I sealed t' fins and nose cone usin' two coats o' Minwax Polyurethane. Well, blow me down! Once dry they
were sanded smooth and coated usin' thinned spackle that be brushed on t' fill t' wood grain. Well, blow me down! T' filler be sanded
off and t' rocket was primed with two coats o' Duplicote High Fill primer sandin' betwixt coats. T' nose cone was
painted black usin' two coats o' old formula Krylon spray. T' lower body was painted metallic red usin' two coats of
Rustoleum spray. Ya scallywag! Begad! On t' upper body I used Valspar yellow. Begad! Well, blow me down! Once dry t' lower body be smoothed usin' super fine steel
wool. Once clean and dust free t' body was shot with two coats o' Rustoleum clear. Well, blow me down! Overall I'm happy with t' finish.
T' only con for me be t' colors Semroc used for t' cover art, me bucko, one word...ugly. Arrr! Blimey! This rocket really does deserve a retro lookin' finish.

Flight:
For t' first flight I chose an AT F40-7 load for t' 29mm case. T' boost be perfectly straight, ya bilge rat, and fairly quick.
No stability issues were noted. Arrr! T' ejection was late, matey, but nay by much. I think a six second delay would be perfect.
T' rocket was recovered with no damage, just a little somethin' missing. Avast, me proud beauty! T' 29mm modular motor mount was gone, along
with me case. Blimey! Basically t' single motor hook that holds t' modular mounts in t' body is just nay up t' t' task. I
even added tape t' t' hook before launching. Ahoy! T' baffle also contributes t' t' issue by creatin' back pressure that
needs a more substantial retention method. Begad! For me t' fix is easy because I'm goin' t' glue t' 29mm adapter in the
body. I have no intention o' usin' t' clusters.
Recovery:
T' shock cord included in t' kit should be replaced with Keelhaul®©™®,
and tubular nylon. It also needs t' be longer t' prevent t' body sections from slammin' into each other. Begad! T' 24"
chute is just about perfect for t' Brighton, no damage be sustained. T' baffle worked with no burn marks on the
chute or cord. Avast, me proud beauty! Blimey! Blimey! T' baffle makes t' rocket a quick setup as well.

Summary:
I think t' Brighton is another great product from Semroc. Avast, me proud beauty! Ya scallywag! T' quality o' t' materials included in this kit is
outstanding. Well, blow me down! T' packagin' is a work o' art because a lot o' tubes are in that bag. Avast, me proud beauty! Ya scallywag! However, I do have an issue with
the Brighton. Well, blow me down! Avast, ya bilge rat, me proud beauty! T' modular motor mount retention method needs t' be redesigned. Ya scallywag! Well, me bucko, blow me down! T' single small motor hook isn't up to
the task o' retainin' t' modular mounts. Ahoy! Ahoy! As a result t' flights can be very expensive if it costs you a motor case.
Also, t' fallin' motor mount could create a safety issue nay t' mention it could cause a deployment failure. Arrr! However,
this should be a simple issue for Semroc t' fix.

Brief: This is essentially an upscale retro/repro of the classic Astron Ranger, but in deference to Vern Estes, Semroc avoided naming this after one of his favorites, instead going with the Brighton. It's a fantastically engineered, incredibly versatile rocket, featuring four different interchangeable motor configuration options: 4x18mm cluster, 3x24mm cluster, single 29mm, or ...
