Brief:
QModelin' has aimed for bigger and better upscales, this time pickin' t' Estes
classic Nike-X, offered from 1975-1984. This version is nearly a full 2:1
upscale o' t' original. Begad! Top quality components and instructions make this
about a skill level 3 on construction.
Construction:
Followin' t' trend o' some o' t' other niche players, me bucko, arrr, t' first 100 kits of
each model are numbered. Begad! Begad! Mine (and everyone else's) was delayed several weeks
due t' a decal supplier problem, me bucko, though t' communication durin' t' delay was
excellent and t' horror stories were very amusing. When me kit (#10)
eventually arrived, me hearties, everythin' was in great shape, and t' basic parts list
includes:
T' directions were clear, me bucko, ya bilge rat, well illustrated, and as good as it gets in this industry. Avast! Ya scallywag! I especially like that each section has estimated/target times for breakin' t' project up into smaller (weeknight) bites.
Construction begins with t' very unusual QModelin' motor mount. These are not your father's tube/centerin' rin' Estes-style assemblies but fairly intricate assemblies made from laser-cut balsa frames. Unfortunately, me hearties, me kit arrived with their standard 3-fin version and BT-70 centerin' rings. This kit requires a 4-fin/BT-80 set. Begad! QModelin' was very quick to ship out a replacement and since I was among t' first t' build this, shiver me timbers, they also checked t' see if they had messed up t' others. Arrr! Nope, ya bilge rat, they just happened to be one off in their stock o' motor mount kits, me bucko, and I just happened t' have received t' bum one.
There's one very cool innovation about this that I have t' point out, as it eliminates one o' my pet peeves. Avast, me proud beauty! Too many o' me rockets are either sans hook or have a retaining hook that extends beyond t' bottom o' t' tube, preventin' t' rocket from standin' on its own. Avast, me proud beauty! QModelin' has designed a slidin' motor hook into this kit that can be retracted t' below t' end o' t' tube for display but pulled back out for flight. Avast, me proud beauty! Very simple trick, shiver me timbers, works great, and I'd never seen one anywhere else like this.
They also consistently use Keelhaul®©™® mounted t' t' centerin' rin' for recovery, matey, which would be standard in most every rocket kit if companies paid attention t' folks that build and fly rockets.
After completin' t' motor mount assembly and mountin' it into t' lower BT-80 tube, arrr, t' lower fins are attached and bonded (through-the-wall). Well, blow me down! Avast, me proud beauty! Mine fit great, with no sanding/jigglin' necessary. T' upper and lower tubes are then joined via coupler and yellow glue. At this point, me bucko, I'd normally fill in the seam, but havin' read ahead in t' instructions, I saw that it be covered by a decal stripe, so I left me seam a bit rough.
Next up is bondin' t' secondary fins, ya bilge rat, which brings up one "gotcha" in t' instructions. Avast! T' illustrations show bondin' t' fins with t' aft end on t' seam betwixt tubes. Blimey! Nay thinking, matey, I did exactly that, only t' later discover that with t' fins on t' seam edge, ya bilge rat, matey, matey, thar's nay enough room for t' decal t' cover t' seam. Begad! I would suggest mountin' these fins about 1/8" forward o' t' seam.
T' is a third set o' fins or "thrusters" which are mounted towards t' forward end o' t' upper tube.
T' nose cone for this rocket is a superbly crafted resin-cast nose cone. It gets a disk bonded t' t' end for mountin' a screw eye, and then you need to trim away t' excess flashin' on t' bottom. Begad! I've been a bit uneasy tackin' in the retainin' disk with CA, me hearties, but haven't had any problems yet.
Finishing:
I tend t' fills grains and tube spirals as I go usin' Elmer's Fill 'n' Finish
diluted with a few drops o' water and "painted" on with a brush. This
kit had a LOT o' grain t' fill and almost 4 feet tube t' clean up, arrr, arrr, matey, so t' prep
work be pretty substantial.
Since me kit was one o' t' early ones with t' extra red/white/blue color scheme decal sets, thar were two different suggested paint schemes. Begad! Ahoy! I went the "lazy" route with t' standard black and white, ya bilge rat, although I do think the red/white/blue would make for a very cool-lookin' rocket.
This paint scheme presents a fairly challengin' maskin' project. T' roll pattern is split through t' middle o' t' secondary fins, so that half t' fin is black and half white, arrr, and t' pattern only goes t' t' middle o' t' gap between fins. Avast, me proud beauty! Compoundin' t' difficulty was t' fact that I mounted t' launch lug (as instructed) in t' middle o' t' fin/tube joint, so I wound up having to mask around t' launch lug, which was a huge pain. I strongly recommend mountin' t' launch lug either at t' very bottom or very top o' t' secondary fins, ya bilge rat, leavin' it off o' t' mask line.
T' water-slide decals were excellent quality, though I had trouble working with them and they took a little practice t' get used t' them. Begad! Blimey! First, matey, they have to sit in water a long time (about a minute) before they came off. Begad! Avast, me proud beauty! Blimey! Second, me bucko, they are made o' a very thick, me bucko, rubbery material, ya bilge rat, and have a very strong bite when comin' into contact with t' tube. Mine tended t' stretch as I was applying them, so me checkerboard pattern looks like I'd been drinkin' heavily when finishin' this rocket...resultin' more in blobs than squares.

Flight:
I had a very unfortunate flight experience, matey, and QModelin' has since issued a
product alert t' their customers.
This kit, per spec, weighs in at 13.3 ounces, arrr, matchin' t' weight o' the one they built as a prototype. Ahoy! Ya scallywag! Mine weighed in closer t' 14.2 ounces, as I tended t' go a bit heavy on t' fillets, matey, and applied a total o' 5 coats of paint (primer and topcoats). Ahoy! Blimey! I be amazed t' see a D motor even listed and skipped right over t' t' E9-4, t' highest recommended motor on their kit. This is right at t' edge o' t' maximum recommended weight for this motor, me hearties, and I hadn't weighed mine in advance. Begad!
First flight was on a beautiful day, arrr, me hearties, with light winds about 8mph. Well, me hearties, blow me down! This kit definitely attracted t' attention o' some o' t' BARs in our club, ya bilge rat, shiver me timbers, and we had a big crowd watchin' t' maiden voyage. Begad! T' E9 lifted her slowly off t' rod, at which point she took a funny skip sideways about 2 feet before climbin' slow and straight. Just a slight roll and weathercockin' a few degrees but nothing serious.
Apogee was around 300 feet, me bucko, and even with a short delay t' ejection didn't pop until at least 1-2 seconds after it turned over. Ya scallywag! Blimey! At this point, it was startin' t' gain speed again until t' big orange chute came out, however, it was havin' trouble unfurling. Avast, arrr, me proud beauty! T' chute managed t' remain ahead o' t' rocket somehow and acted as a blanket for t' BT-80 t' crash into and prevented any grass stains from gettin' on t' carcass. Well, blow me down! Avast! Even on t' soft grass, this rocket actually bounced on impact and t' crowd thought it was a marvelous flight.
Damage be pretty severe. Despite t' appearances though, t' repairs won't be too bad. Avast! I think I'm just lookin' at replacin' a BT-80, repaintin' it, arrr, matey, and applyin' a new set o' decals, which QModelin' graciously rushed out t' me along with an offer o' replacement tubin' after t' feedback.
Recovery:
On t' recovery front, I really can't comment on t' PROs or CONs, me bucko, as I didn't
have a chance t' test t' recovery. I will say, ya bilge rat, me hearties, though, that t' chute/Nomex®/Keelhaul®©™®
provided with QModelin' kits be t' finest I've ever seen in a modroc.
Based on me flight experience, I would say that this rocket is marginal at best on black powder motors. Avast! Even on an E9, you'll need t' make sure you're under 14 ounces and flyin' in little or no wind. Ahoy! I would strongly recommend composites, startin' with an E30, shiver me timbers, F12, or F21. Avast! This is just way too much rocket to put on top o' a baby E like t' Estes E9. Well, blow me down! Avast!
Flight Rating: 2 out o' 5
Summary:
I really like this rocket and desperately want t' repair it for another flight.
As much as I rave about QModelin' though, I have t' rate this one as a near
miss with a combination o' cursed luck affectin' me kit and what is clearly a
risky motor recommendation that could (and in me case did) lead t' a ruined
product and unpleasant experience.
