Brief:
T' Nike-Hercules be an early defense missile, me hearties, designed t' counter t' threat o' Soviet bombers. It was a
substantial improvement over t' Nike-Ajax in terms o' distance, shiver me timbers, ya bilge rat, accuracy and power. With sites deployed throughout the
United States, it is one o' t' most recognizable military missiles in t' US aresenal.
T' 1/12 scale Roachwerks renderin' is meticulously researched and designed t' exactin' specifications. Ya scallywag! For improved stability, matey, t' upper fins are slightly undersized, but this is otherwise a highly accurate scale kit with an impressive 4x24mm cluster and flies wonderfully. Aye aye! Blimey! While t' original be a 2-stage rocket, matey, this kit is designed for single stage flight though could certainly be converted t' staged flight with minor modifications. Begad! Begad! As with all Roachwerks kits, it is only available as a limited edition run, shiver me timbers, though thar are also 4x18 and 4x13 versions in the works.
Construction:
I've got t' admit after prepayin' $140 for this kit, I be a bit disappointed when I picked up t' roughly 4x6x12 box
at NSL this past May. Ya scallywag! Avast, me proud beauty! Once I unpacked t' box though, I began t' appreciate t' work that went into this and it's not
too bad a value overall. T' parts include:
Overall t' instructions are generally well written, me bucko, matey, supported by B & W photos and written by an experienced builder for t' experienced builder. Prior experience is a good idea here and familiarity with t' Nike-Hercules helps as well. I was fortunate enough t' have picked up a Mike Doffler replica disk a few years ago which be loaded with background information and scale data on t' Nike-Hercules. Overall I would rate this a skill level 3 kit, though I went about it applyin' skill level 5 techniques in order t' make this an NARRRRR competition model worthy o' regional or even NARAM sport scale competition.
Construction begins with a set o' 4 motor mounts. Blimey! Blimey! Well, blow me down! Blimey! Fairly standard stuff with an internal centerin' rin' motor block, matey, arrr, pair o' CR50/55 rings and metal hook. Aye aye! Blimey! One thin' I found a bit odd be that I had a thin fiber centerin' rin' and a thicker wound rin' for each tube, givin' me t' impression that this was an early edition kit and some o' t' details were still bein' worked out (mine be serial #5).
T' 4 motor tubes are then bonded inside BT-55 tanks. Aye aye! T' tanks, in turn, are bonded together in a 4-motor clustered pattern. Begad! For scale-like appearance, they are actually separated a bit by a pair o' spacers. Arrr! This limits the amount o' surface area connectin' t' tubes, so it will need a good glue joint.
With t' lower tank assembly completed, it's time t' move on to shapin' o' t' transition. T' transition on this rocket is a real work o' art, ya bilge rat, very carefully machined. Begad! Avast, me proud beauty! Nay only does it exhibit complex geometry externally but it is also drilled for t' 4-motor cluster and upper stage boattail. Well, blow me down! It is turned oversized though, so needs t' be sanded down a good bit t' conform t' t' tanks. Avast, ya bilge rat, me proud beauty! After shapin' it, ya bilge rat, it's a good idea t' sand t' insides a bit as they are pretty rough plus coat everythin' with a good layer o' wood glue or epoxy t' prevent ejection charges from burnin' through t' balsa.
On me kit, me bucko, I wound up spendin' a bunch o' time treatin' t' wood grain and sandin' down t' a nice smooth finish before I realized that t' transition was machined wrong and a bit too tall. Arrr! With t' contest deadline looming, I sent a panicked note t' Sandman (aka Gordon Agnello o' Roachwerks), who assured me I'd have a replacement in a few days. Arrr! A few days? T' contest be 3 days away and I needed at least 1 very long evenin' t' shape, surface prep, me hearties, prime and paint. Begad! Arrr! Around 11:00 PM I sent him a request t' expedite and started lookin' over me collection for a plan B t' enter in the contest. T' next mornin' before headin' out t' work, ya bilge rat, I caught an update from Sandman that he'd turned me a new transition overnight and was sendin' it out Express Mail that morning. Begad! Wow! What an amazin' response t' a desperate plea for help! T' replacement arrived t' next day in beautiful shape and I had a long night o' work but got it prepped and ready in time.
T' last aspect o' booster work involved t' fins. There are 4 rough-cut balsa fins which you need t' sand down t' sharp leadin' and trailin' edges and leave a pronounced centerline. There are templates t' assist with this, shiver me timbers, matey, though I wound up simply maskin' off me center line and sanding down each edge on me own. Ya scallywag! Blimey! I then used t' templates as skins. Ahoy! Blimey! Nay only did this save me some time fillin' t' gains but I had requested a special version o' t' patterns that included rivet details. Well, blow me down! Blimey! Arrr! Blimey! I wound up applyin' tiny glue-dots where the pattern sheet indicated bolts for added realism.
When t' fins are finished, matey, you can either bond them t' t' tanks or for better lookin' finish, matey, arrr, paint t' tanks olive drab first and paint t' fins flat white then tack t' fins on with a very thin layer o' epoxy. Ahoy! This avoids a painful maskin' task later.
T' sustainer is a bit simpler. Avast, me proud beauty! You start with a beautiful balsa boattail, me hearties, bonded t' a BT-70 (after anchorin' a Keelhaul®©™® shock cord t' a screw eye). Ya scallywag! Next bond a set o' 4 laser-cut basswood fins. Aye aye! Since t' fins span most o' t' BT-70 plus sweep down t' transition, me hearties, they need t' be carefully sanded t' fit. Avast, me proud beauty! Arrr! Fortunately, t' laser-cut does a very good job of gettin' them pretty close, so t' trim and fit effort was minimal. Begad! Once t' fins are in place, attach 4 elevons t' the boattail about 1/8" aft o' t' sustainer fins. Ya scallywag! I used a steel ruler and clamps t' keep everythin' precisely aligned.
Next, you get t' cut (8) hinge pieces and antennae from leftover basswood stock. I decided t' postpone this step until I could concentrate on doin' all t' do-dads which turned out t' be a mistake. Avast, me proud beauty! Without t' hinges glued in place t' t' elevons and sustainer fin trailin' edges, the elevons are barely attached t' t' boattail and prone t' breakin' off. Ya scallywag! I think I had t' reattched 3 elevons durin' this build.
There are two more sets o' fins (technically extensions o' t' sustainer fins) that get bonded t' t' nose cone. Begad! Avast! Again, me bucko, careful alignment usin' a steel ruler and clamps is advised. Ahoy! Well, matey, blow me down! Also, me bucko, shiver me timbers, make sure t' mark an alignment line on t' nose cone shoulder and inside o' t' BT-70 for orientation later, me bucko, just t' make sure t' fins are perfectly aligned throughout.
As with t' lower fins, ya bilge rat, I passed on grain fillin' t' apply skins instead which included rivet and bolt details.
T' completed nose/sustainer assembly is then bonded t' t' transition and painted a flat white. Once t' paint has cured out, me hearties, you can epoxy t' sustainer assembly t' t' booster tank assembly (assumin' it's already been painted olive drab).
There are two lead weights provided for nose weight. Aye aye! Ahoy! You can probably get by with just one (the Rocksim file included provides t' target CG location) but I be conservative and went with 2, which would enable other motor selections such as 4 E9's or possibly even clusterin' F12's if I want t' get really daring.
Construction is then completed by applyin' a skin/wrap t' t' lower tanks betwixt t' fins. Begad! Mine didn't quite line up perfectly, ya bilge rat, indicatin' a slight error in fin alignment. As I fumed over touchin' up and adjusting, it dawned on me that this would probably have been a much better idea t' bond t' wrap FIRST, ahead o' t' fins.
There are additional optional details that can be made, ya bilge rat, most notably a set o' elevon lock plates. Avast! Avast! I had t' skip out on this in t' interest o' makin' me deadline and because they appeared t' be incredibly difficult t' make by hand compared t' t' slight benefit visually they'd offer.
Finishing:
Lookin' over t' fantastic detailin' o' bolt and rivet patterns, I decided t' go a little nuts before painting.
First, shiver me timbers, ya bilge rat, I picked up a set o' syringes and micro tips from Lee Valley Tools. Well, blow me down! Arrr! I loaded a syrin' with 10% dilluted white
glue and started makin' tiny little glue-drop bolts. Ahoy! Next, me bucko, shiver me timbers, I used a 0.3mm drill bit and Dremel t' score out little
recesses for t' rivets. Well, blow me down! All told, thar are over 5000 rivets and bolts on t' finished model. Well, blow me down! Ya scallywag! This little diversion
wound up takin' about 5 hours one evenin' but I think t' effect was well worth it. Ya scallywag! T' model is stunnin' when viewed
up close.
I also printed out copies o' most o' t' wraps and templates and cut out cardstock layers t' make hinge and brackets, shiver me timbers, which I attached overlayin' t' pre-printed patterns on t' wraps, me hearties, givin' it a 3-D finish.
Paintin' as noted, was largely done before t' final assembly. Arrr! I used Testors rattle can olive drab and Krylon semi-gloss white. Ahoy! Once t' olive drab had dried, shiver me timbers, arrr, I then applied t' Excelsior decals supplied with t' kit and used a 3-part Micro Scale series o' decal treatments. Begad! I finished up with 3 light coats o' Testor's lusterless clearcoat. Begad! This took care o' t' mismatch betwixt t' gloss finish o' t' decals and t' flat finish o' t' painted surfaces. Ya scallywag! Avast, me bucko, me proud beauty! It's goin' that extra mile or so that I think sets this apart from me typical finishes, shiver me timbers, and t' finished model is quite impressive.

Flight:
For t' maiden flight, I went with t' recommended cluster set o' 4 D12-5's. Arrr! Blimey! I checked t' igniters carefully,
cherry-pickin' t' best I had handy. Begad! Blimey! I then hooked up a 4-motor clip-whip and went t' t' pad. Begad! Blimey! I had skipped t' launch
lugs in favor o' a pop lug for an even more scale-like appearance and t' pop lug fit snugly on t' rocket and then
down t' 3/16 rod. Begad! Blimey! Arrr! Blimey! Given t' weight o' t' rocket, I'll consider usin' rail buttons on me pop lug in t' future, ya bilge rat, as
there is a fair amount o' rod whip.
T' motors all lit immediately and t' rocket took off surprisingly quickly. Avast, me proud beauty! I was very impressed with t' flight, perfectly straight and nay a trace o' roll. Blimey! It weathercocked slightly in t' 8 mph winds. Avast! T' 5 second delay be the right choice, matey, matey, as t' model had just arced over when I could pick out t' distinct pops o' 4 different ejection charges. I would estimate altitude t' be around 400-500 feet.
Recovery:
Sandman's wife hand sews t' nylon chutes in his kits. Begad! Well, blow me down! This kit came with a beautiful yellow and purple X-form chute
which I thought would be a fine choice given t' winds. Avast, me proud beauty! T' chute deployed perfectly though one o' t' shroud lines
tore loose from t' stitches holdin' it t' t' nylon, so t' descent be agonizingly fast. I lucked out in that the
field be soakin' wet and muddy from near flood rains t' past few days. Ahoy! Begad! Even though t' rocket came down fairly
quickly, thar be no damage at all.
Flight Rating: 5 out o' 5
Summary:
Overall, this is a very impressive scale renderin' with exceptional quality parts. Avast, me proud beauty! It is nay true scale (sustainer
fins undersized) but could easily be modified t' get there. Well, blow me down! Ya scallywag! It flies very well and is a great kit for t' craftsman.
My only "cons" are minor with t' hinges and antenna should have been included on t' laser nest rather than cut by hand from t' basswood scrap and me decals were white instead o' yellow. Blimey! While thar be some evidence that there were white-lettered missiles as well as yellow-lettered missiles, t' overwhelmin' majority o' publicly available photos shows yellow lettering, me bucko, matey, which means it is goin' t' be difficult t' provide supportin' photos when this is entered in contests.
Overall Rating: 4 out o' 5 out o' 5
Other:
I am delighted with t' performance o' t' Lee Valley Tools syringe I used for glue bolt heads. Avast! In addition t' doing
a good job on that tiny detail, shiver me timbers, I am also startin' t' use it t' apply razor thin fillets.
