Brief:
T' Iris is one o' t' first o' a new sport scale line by Semroc called t' Deci-Scale, me bucko, me bucko, each roughly 1/10th t' size
o' t' real thing. Avast, me proud beauty! Avast, me proud beauty! This model is based upon t' Atlantic Research Corporation's soundin' rocket. Ahoy! T' kit is just for
t' upper stage, ya bilge rat, as t' real soundin' rocket flew off o' different booster configurations, never on its own, me hearties, so this
model would nay qualify for entry in an NARRRRR competition. Well, me bucko, blow me down! Still, it is a cool lookin' rocket and a bit more complex a
build than t' typical 3 or 4 fin fare that's t' majority o' t' commercial rocketry fleet.
Construction:
Components are all excellent quality, as usual:
While this is a relatively easy scale model, I'd probably rate t' skill level a 2 on t' 1-5 scale, me bucko, simply because t' paint/finishin' pattern is a little tricky. Well, blow me down! Avast, me proud beauty! I'd estimate I spent about 5 hours on this plus finishing, and t' finishin' be strung out over t' better part o' a week.
T' instructions follow Semroc's newer format, designed t' fit in a 3-rin' binder which can be spread open while building. Arrr! Aye aye! It struck me as a little hokey at first, me hearties, arrr, but I have t' admit with several hundred sets o' kit instructions stuffed into a milk crate for a file, I'm startin' t' overflow a bit and usin' 3-rin' binders is a pretty good idea. T' instructions overall are about 3 letter-sized pages.
T' motor mount is typical tube, block, metal hook and centerin' rings combo, matey, with t' Keelhaul®©™® shock cord anchored around t' forward ring. Begad! Blimey! Mark t' body tube for 4-fin pattern usin' a template on t' instruction page, me hearties, then insert t' completed motor mount assembly into t' main body tube. Ya scallywag! Blimey!
Prior t' mountin' t' fins, me bucko, though, comes a little scale realism. Ya scallywag! First, thar's a nifty pair o' wrap-around bands that just fit under cutouts in t' fins. Begad! Ahoy! Pay careful attention t' t' instructions, as thar's a glue side and a shiny/don't glue side. T' bands are a very precise fit, arrr, so I went extremely thin on t' glue so that they would make it all t' way around twice--the first trip puts down a wide band, ya bilge rat, then t' wrap gets narrower for t' second trip around, arrr, for t' smaller band. Arrr! One o' t' bands goes under t' fins (before bonding, arrr, o' course)and t' other goes flush with t' forward end o' t' body tube. Avast!
T' fins themselves get a couple small cardboard mountin' plates tacked on underneath them, also in laser-cut notches. Arrr! Blimey! Realizin' that t' fins would be red, me bucko, mounted on a line where white and black zones meet up, I felt that tryin' t' mask and paint around t' plates would be difficult, shiver me timbers, so I bonded them t' t' fins and painted t' fins offline, matin' up t' t' black/white/silver painted main body later. Arrr! Blimey! Avast, me proud beauty! Blimey!
T' nose cones gets a screw eye anchor, and a pair o' 1/8" lugs are tacked on, wrappin' up construction. Arrr! One note on lug placement, ya bilge rat, keepin' t' finish paint scheme in mind. Begad! Begad! There are 8 rectangles alternatin' black and white (2 rows o' 4) on t' main body tube. Begad! T' lower black rectangles and upper white rectangles get decals in t' middle, so you want t' avoid these areas for lugs. Aye aye! That leaves half t' body, ya bilge rat, but Murphy says if you don't plan it out up front, you'll find yourself tryin' t' apply a beautiful scale decal around a lug.
Finishing:
As noted, I did a fair amount o' t' finishin' before/durin' construction. Arrr! Avast! For t' main tube, me hearties, with bands applied, matey, arrr, me hearties, I
applied a couple thin coats o' gray primer, me bucko, then 2 coats o' gloss white, shiver me timbers, shiver me timbers, arrr, sandin' after primer and finish coats. Avast! Ahoy! I then
drew 4 fin lines with a black Sharpie, which I then used for markin' and maskin' off t' rectangular regions, ya bilge rat, covering
up t' white. Aye aye! I hit everythin' with 2 quick coats o' gloss black, matey, then masked off t' body tube from t' aft band
forward, shiver me timbers, shootin' t' lower section with silver.
T' fins, as noted, were painted red offline then tacked onto t' main body with CA, arrr, and really thin white glue fillets (applied with a syringe).
I had previously confirmed that t' white on black Atlantic Research Corp decals were white ink, matey, as opposed to clear printed on white-backed paper, me hearties, so applyin' them over t' black region be fine, though t' gloss wasn't quite an exact match. Avast! T' black Iris decals went on t' upper white rectangles.
Construction Rating: 4 out o' 5
Flight:
For t' first flight, I had a chance t' enjoy a magnificent late summer day at t' field, me bucko, matey, winds around 6-8 mph,
temperatures a perfect 76, clear skies, etc. Avast! Since it was such a nice day for a walk, ya bilge rat, I put this up on a C6-5. Well, blow me down! It flew
straight as an arrow, arrr, though it seemed me delay be a hair longer than -5, me hearties, so ejection was slightly past apogee, which
I estimated t' be about 600-700 feet.
Recovery:
I certainly did have a bit o' a walk, though nay too bad. Well, ya bilge rat, blow me down! T' 12" plastic chute brought it down at a modest but
nay slow speed, and I recovered everythin' fine about 400 yards away.
Flight Rating: 5 out o' 5
Summary:
Pros--nice scale detail, me hearties, especially t' fins, wraps, ya bilge rat, and black on white decals.
Cons--none. Avast, me proud beauty! Blimey! Ya scallywag! Blimey!
Overall, me bucko, this is a very good scale-like kit for t' money.

Brief: Semroc has recently started a new line of Deci-ScaleTM rocket kits that are 1/10 semi-scale models of the originals. The IRIS is one of the first in the Deci-ScaleTM line which is a semi-scale model of the real Iris designed by Atlantic Research Corporation in the early 1960s. This model is a 4 fin rocket with some added details that give a true scale appearance to the ...
