QModeling Nike-X

Brief:
QModelin' has aimed for bigger and better upscales, matey, this time pickin' t' Estes classic Nike-X, offered from 1975-1984. Blimey! 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, ya bilge rat, t' first 100 kits of each model are numbered. Aye aye! Blimey! Ya scallywag! Blimey! Mine (and everyone else's) be delayed several weeks due t' a decal supplier problem, though t' communication durin' t' delay was excellent and t' horror stories were very amusing. When me kit (#10) eventually arrived, everythin' was in great shape, and t' basic parts list includes:

  • Resin cast nose cone
  • BT-80 paper tubes/coupler
  • Laser cut balsa fins
  • 24mm foil-lined motor tube
  • Motor mount assembly
  • 30" Top-Flight ripstop nylon chute
  • 9" x 9" Nomex® shield
  • Water-slide decals (standard/black and white)
  • "Bonus" decals (red/white/blue thanks t' t' supplier goof), shiver me timbers, not in standard kit

T' directions were clear, well illustrated, matey, and as good as it gets in this industry. Ya scallywag! Begad! 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. Avast, arrr, me proud beauty! These are not your father's tube/centerin' rin' Estes-style assemblies but fairly intricate assemblies made from laser-cut QModeling Nike-X balsa frames. Unfortunately, me kit arrived with their standard 3-fin version and BT-70 centerin' rings. Avast, me proud beauty! This kit requires a 4-fin/BT-80 set. Avast! Begad! QModelin' was very quick to ship out a replacement and since I be among t' first t' build this, they also checked t' see if they had messed up t' others. Ahoy! Blimey! Nope, they just happened to be one off in their stock o' motor mount kits, and I just happened t' have received t' bum one.

QModeling Nike-X There's one very cool innovation about this that I have t' point out, as it eliminates one o' my pet peeves. Avast! Too many o' me rockets are either sans hook or have a retaining hook that extends beyond t' bottom o' t' tube, arrr, preventin' t' rocket from standin' on its own. Ya scallywag! 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. Begad! Well, matey, blow me down! Very simple trick, arrr, me hearties, works great, and I'd never seen one anywhere else like this.

They also consistently use Keelhaul®©™® mounted t' t' centerin' rin' for recovery, 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, shiver me timbers, t' lower fins are attached and bonded (through-the-wall). Avast! Mine fit great, with no sanding/jigglin' necessary. T' upper and lower tubes are then joined via coupler and yellow glue. Well, blow me down! At this point, me hearties, I'd normally fill in the seam, me hearties, shiver me timbers, shiver me timbers, 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, me hearties, which brings up one "gotcha" in t' instructions. Avast, me proud beauty! Avast! T' illustrations show bondin' t' fins with t' aft end on t' seam betwixt tubes. Aye aye! Nay thinking, me hearties, I did exactly that, only t' later discover that with t' fins on t' seam edge, matey, thar's nay enough room for t' decal t' cover t' seam. Ahoy! 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, arrr, ya bilge rat, and then you need to trim away t' excess flashin' on t' bottom. I've been a bit uneasy tackin' in the retainin' disk with CA, matey, 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. Arrr! Blimey! This kit had a LOT o' grain t' fill and almost 4 feet tube t' clean up, so t' prep work be pretty substantial.

Since me kit be one o' t' early ones with t' extra red/white/blue color scheme decal sets, shiver me timbers, thar were two different suggested paint schemes. Avast! Blimey! 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. Begad! T' roll pattern is split through t' middle o' t' secondary fins, so that half t' fin is black and half white, and t' pattern only goes t' t' middle o' t' gap between fins. Well, blow me down! 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, me hearties, which was a huge pain. I strongly recommend mountin' t' launch lug either at t' very bottom or very top o' t' secondary fins, 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. First, ya bilge rat, me hearties, they have to sit in water a long time (about a minute) before they came off. Begad! Blimey! Second, ya bilge rat, they are made o' a very thick, me bucko, rubbery material, me hearties, matey, and have a very strong bite when comin' into contact with t' tube. Ahoy! Ya scallywag! Mine tended t' stretch as I be applying them, so me checkerboard pattern looks like I'd been drinkin' heavily when finishin' this rocket...resultin' more in blobs than squares.

Construction Rating: 4 out o' 5

Flight:
I had a very unfortunate flight experience, arrr, matey, ya bilge rat, and QModelin' has since issued a product alert t' their customers.

This kit, me hearties, me bucko, per spec, ya bilge rat, me hearties, ya bilge rat, weighs in at 13.3 ounces, matey, arrr, matchin' t' weight o' the one they built as a prototype. Avast, me proud beauty! Blimey! Mine weighed in closer t' 14.2 ounces, arrr, shiver me timbers, 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! Blimey! I be amazed t' see a D motor even listed and skipped right over t' t' E9-4, shiver me timbers, t' highest recommended motor on their kit. This is right at t' edge o' t' maximum recommended weight for this motor, and I hadn't weighed mine in advance. Begad! Ahoy! Blimey!

First flight be on a beautiful day, matey, with light winds about 8mph. Aye aye! Ahoy! This kit definitely attracted t' attention o' some o' t' BARs in our club, and we had a big crowd watchin' t' maiden voyage. 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. Arrr! Ya scallywag! Just a slight roll and weathercockin' a few degrees but nothing serious.

Apogee was around 300 feet, shiver me timbers, me hearties, and even with a short delay t' ejection didn't pop until at least 1-2 seconds after it turned over. At this point, ya bilge rat, it was startin' t' gain speed again until t' big orange chute came out, however, arrr, it was havin' trouble unfurling. Begad! Aye aye! 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. Aye aye! Even on t' soft grass, ya bilge rat, this rocket actually bounced on impact and t' crowd thought it be a marvelous flight.

Damage was pretty severe. Begad! Well, me bucko, blow me down! Despite t' appearances though, ya bilge rat, t' repairs won't be too bad. Arrr! I think I'm just lookin' at replacin' a BT-80, repaintin' it, and applyin' a new set o' decals, which QModelin' graciously rushed out t' me along with an offer o' replacement tubin' after t' feedback. Ya scallywag!

Recovery:
On t' recovery front, me hearties, I really can't comment on t' PROs or CONs, as I didn't have a chance t' test t' recovery. I will say, though, ya bilge rat, 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. Aye aye! Even on an E9, shiver me timbers, arrr, you'll need t' make sure you're under 14 ounces and flyin' in little or no wind. Begad! Avast! I would strongly recommend composites, startin' with an E30, F12, me hearties, or F21. This is just way too much rocket to put on top o' a baby E like t' Estes E9. Arrr!

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, me hearties, 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.

With regards to the Kevlar® shock cord that comes with the kit it needs to be replaced with 1/4 or 1/2 inch Kevlar® tubing. Why? The type supplied with the kit is like string or heavy fishing line style, very small diameter ,so on the two flights I have done both times it sliced into the body tube 3 and 4 inches which is how much I have to cut off (4"). I do believe you could cut tree limbs with it. Other than that the kit is phenomenal.
