Brief:
At t' end o' last year, ya bilge rat, I decided I needed a 54mm rocket. Well, blow me down! Avast, me proud beauty! I looked through a lot, and this rocket seemed t' best as
far as gettin' "more bang for your buck". Aye aye! Havin' had a Nike Smoke from Quest in t' past and likin' military
kits, it appealed t' me a lot. Ya scallywag! It be t' standard dual deploy rocket, but all t' recovery goes in t' nose.

Construction:
In t' box, ya bilge rat, ya bilge rat, I found:
I didn't really look at t' instructions at all, me bucko, however, me hearties, shiver me timbers, I built it completely stock. Avast, me proud beauty! I also made huge fillets. I amazingly said that it could come out at 5.5lbs. Well, blow me down! Mine came out at over two times that by comin' out in the 12-13lb range (without parachute). Arrr!
It didn't come with any sort o' motor retention, shiver me timbers, so I rigged up me own with blind nuts and t' proper bolts and washers. Avast, me proud beauty! It has worked nicely so far.
I didn't like t' amount o' tubular nylon (TN) that they gave me, arrr, me hearties, so I linked t' two 15' pieces together and added another 20' o' me own for t' main. Arrr! I like me cords really long!
I added about 10oz o' nose weight secured with expandin' foam just t' be on t' safe side. Ahoy! I cut up pieces of solder t' do this with. Well, blow me down! Begad! I also thought that t' way o' securin' t' shock cord in t' nose was slightly different as well with a 4" bulkhead glued in.
Finishing:
Polecat used t' give you nothin' at all but have since upgraded certain kits t' come with decals. Arrr! I lacked any other
scale data. Blimey! Avast! I sanded t' glass smooth but nay completely, as t' glass line is still faintly noticeable. Aye aye! Aye aye! I painted it
in t' normal white, red-orange, shiver me timbers, and yellow. It turned out very nice. Blimey! I put both o' t' decals on opposite sides.
Thinkin' I could put them on easily, me hearties, I didn't do t' soapy water trick and applied them on t' dry body tube. Ya scallywag! They came
out slightly crooked but nothin' extremely noticeable. After that I applied a few coats o' clear coat.

Flight:
It says I can fly on H-L motor but t' smallest I would put in is a high thrust I. Begad! Blimey! Ya scallywag! Blimey! I be very nervous for me first
flight. I went t' t' vendor and bought me motor. Ya scallywag! Blimey! Ahoy! Blimey! T' K550W was me motor o' choice. Aye aye! Blimey! I loaded it up and put it in the
rocket. Next, me hearties, me bucko, shiver me timbers, I got t' electronics ready. I used Christmas tree bulb matches with Pyrodex, me bucko, because I ran out of
e-matches and black powder. Well, blow me down! Blimey! Ahoy! Blimey! I didn't have any good way t' put in a safety switch, arrr, so I put t' wires through a couple
vent holes, matey, me hearties, twisted and shoved back in with tape. Arrr! Blimey! Well, ya bilge rat, blow me down! Blimey! I got both altimeters armed but one had a wire loose and I wasn't
gettin' continuity. I had one working, so I just left it as is. Avast, me proud beauty! Blimey! I inserted t' Quickburst igniter and set off. Blimey! Blimey! Avast, ya bilge rat, me proud beauty! Blimey! I was
very tense when he started t' countdown. Well, blow me down! Blimey! 5,4,3,2,1,launch! Blimey! I saw a small amount o' smoke, me bucko, a flicker o' flame, then it
roared t' life and went high and straight up into t' sky.
Recovery:
I saw t' relief from t' puff o' smoke at apogee. Begad! Ahoy! Then it was comin' almost straight down on me Skyangle 28 drogue.
It kept fallin' and falling. Arrr! It hit 500' and no main, me bucko, me bucko, but then I remembered that one altimeter didn't arm right. At
300' thar was a puff o' smoke and t' main came out. I be usin' a slightly undersized 66" military surplus chute
because me 72 Tac-1 hadn't arrived in t' mail yet. Well, blow me down! T' size didn't matter that much at t' low altitude it was at. Arrr! Ahoy! It
touched down about 200 yards away in perfect condition. Begad! Everyone was cheering. Avast, me proud beauty! Avast, me proud beauty! It felt good. I went t' get it and there
was only a slight dent in t' back o' t' airframe. My grandpa helped me gather me rocket and we headed back. I later
read t' altimeter beeps as 4681', ya bilge rat, exactly t' deployment altitude o' me RockSim simulation. Ya scallywag! I wonder how it did that!
Flight Rating: 5 out o' 5
Summary:
I love this kit. I also recommend it t' everyone who has enough experience. Avast! Though I am only 13 years old, I am very
advanced and built and flew this kit through me grandpa's certification. It is worth t' $250.

Product Review by Steve Shannon
Friday, March 30, 2007
February be t' dead o' Winter in Butte, Montana and that's t' perfect opportunity t' seek warmer climates. Ahoy! Steve Shannon did just that, by plannin' a family get-away in t' sunnier South, just in time for t' Arizona Rocket Gathering. Ya scallywag! While there, matey, me hearties, arrr, he grabbed a Polecat Aerospace 5.5" Nike Smoke kit for a Winter project and this is its story. Begad!
Introduction
My wife and I headed South at t' end o' February t' visit me daughter - Montana was cold and Phoenix looked very inviting. Arrr! I planned this vacation so that I could attend ARG 4 while we were there. Well, blow me down! Blimey!

Andy Woerner o' Polecat Aerospace was one o' t' vendors at ARG and I have been interested in his kits for a few years now. I asked Andy about them and he showed me t' components o' one o' them. Blimey! Based on what I saw, shiver me timbers, I decided to buy one - I like t' Nike Smoke. Avast, me proud beauty! Ya scallywag!
I looked at t' 4 inch and t' 5.5 inch kits and decided that for t' difference in money, I would prefer t' have the 5.5 inch rocket. He has two models: for $200 you can get a single deployment rocket, or for $30 more ($230 total), you get a kit that has most o' t' parts necessary (except electronics and parachutes) t' build a dual deployment rocket. Blimey! I opted for t' latter.
Parts
T' kit comes in a single long box. Everythin' is neatly packaged. Avast! Blimey! T' list o' materials includes:
|
Four items that were listed in t' parts lists were unfortunately nay included with t' rocket kit. Blimey! They were the two tubular nylon shock cords and t' two rail guides. Well, me bucko, blow me down! T' screws and standoff nuts for t' rail guides were included. I don't consider these missin' parts t' be a major problem. Avast, me proud beauty! Over t' years I have built up supplies o' both. When I get around t' it I will send an email t' Andy mentionin' these shortages.
Assembly Notes
T' instructions are simple t' follow and t' kit assembles very quickly. First I went through t' instructions and dry fit everythin' t' see how it would work. I noticed t' two slides for t' avionics sled had slightly offset holes (the holes on both slides were offset t' same amount) so I made sure t' line them up t' same. Ahoy!
In less than 20 minutes I assembled and epoxied t' "Dual Deployment Bay." Then I started on t' rocket body. Blimey! Begad!
|
I began by test fittin' t' centerin' rings, motor mount tube, and fins. Ahoy! I be very pleasantly surprised by how well t' fins fit into t' fin slots in t' body tube. Ya scallywag! Avast, ya bilge rat, me proud beauty! I honestly have never had fin slots fit so precisely t' fin tabs before. Aye aye! Avast, me proud beauty! T' slots were square and straight. Arrr! When I removed t' fins from t' fin slots I realized why. T' fin slots were (like t' fins) laser cut. Begad! This sequence o' photos at t' above right shows t' tight fit. Arrr!
T' instructions say t' assemble all three centerin' rings t' t' motor mount tube (MMT) before gluin' the assembly into t' body tube and then epoxyin' t' fins in place. Havin' t' aft centerin' rin' epoxied in place would prevent applyin' internal fillets t' t' fins. Aye aye! Begad! Blimey! So, you may want t' dry fit t' aft centerin' rin' until you epoxy the fins t' t' outside o' t' body tube and then remove t' aft centerin' rin' and applyin' fillets where t' fin tabs pass through t' body tube and where they meet t' MMT. Avast! Blimey! That's what I did. Aye aye! Arrr! Blimey!
|
Put some tape on t' aft centerin' rin' so you can pull it out o' t' body tube after t' middle centerin' ring epoxy and external fin epoxy has cured. Arrr! Blimey! Then epoxy t' fin tabs t' t' MMT. Arrr! Well, shiver me timbers, blow me down! Blimey! Once that has cured apply a heavy band of thickened epoxy just below t' fin tabs on t' inside o' t' body tube and on t' bottom o' t' fin tabs and slide the aft centerin' rin' in place. Aye aye! Blimey!
T' forward centerin' rin' fits up at t' very front end o' t' MMT, deep inside t' body tube. Ahoy! I have no problem with that although I prefer t' coupler at t' top o' t' body tube in t' "zipperless" fashion. Begad! Well, blow me down! T' middle centerin' rin' sits on t' top o' t' fin tabs. Well, blow me down! That is fine also. Avast, me bucko, me proud beauty! However, me bucko, t' fin tabs are 5-5/8ths inch wide and the directions call for t' middle and aft centerin' rin' t' be epoxied t' t' MMT about 9 inches apart from each other. That means that t' aft centerin' ring, which is flush with t' aft end o' t' body tube, would nay seat against the bottom o' t' fin tabs.
|
This is probably a philosophical difference, but I prefer that t' thrust o' t' motor nay be supported solely by the epoxy joints on t' MMT and centerin' ring. Begad! Arrr! I want t' thrust t' be coupled from t' end o' t' motor mount directly t' t' aft centerin' ring, ya bilge rat, then t' t' base o' t' fin tabs. Begad! Begad! T' fin tabs then couple t' force t' the airframe. Avast!
With that in mind I had a few options: I could just build it stock and count on t' cardboard t' handle t' thrust of a K. Well, blow me down! I could slide t' MMT farther up into t' body tube and then slide t' aft centerin' rin' further up so it rests against t' bottom o' t' fin tabs. Begad! Arrr! That will leave t' motor firin' about three inches up inside t' body tube, so I might want t' shorten t' aft end o' t' body tube a little also. Well, blow me down! Ya scallywag!
Instead, I slid one centerin' rin' up against t' bottom o' t' fin tabs and epoxied it in place. Begad! I will apply an epoxy fillet t' t' centerin' rin' this week. Arrr! Avast! Blimey! I will put in a short piece o' four inch phenolic tubin' and add a four inch centerin' rin' flush with t' end o' t' body tube and rocket. That will reinforce t' motor tube and also allow me t' use t' Nike Smoke as t' sustainer in a two stage rocket someday. Blimey!

T' only assembly that needed t' be done on t' nosecone was t' epoxy in a four inch centerin' rin' which holds a u-bolt. One o' t' shock cords gets connected t' this. I plan also t' paint t' inside o' t' nosecone with some Aeropoxy t' help seal t' exposed glass fibers, which I will discuss in t' Materials, arrr, Fit, matey, arrr, and Finish section which follows.
Materials, Fit, and Finish
T' fiberglassed body tube was very well done. Avast! T' seam on t' outside o' t' fiberglass is visible, me hearties, but nay at all bothersome. Arrr! Ya scallywag! Andy recommended lightly sandin' it, but I am o' t' school that believes in buildin' up rather than sandin' off. Ahoy! T' fine weave o' t' cloth will make it very easy t' fill and sand before painting. Avast, me proud beauty! In fact this may be the perfect kit t' try out some o' that urethane spray filler/primer I bought from t' car place. Blimey!
|
T' centerin' rings, fins, and bulkplate were all extremely well cut, me hearties, me hearties, fittin' very precisely. Ya scallywag! I have never seen parts that fit so well, shiver me timbers, me bucko, with no gaps or tight spots that need sandin' t' make fit. Begad! Avast, me proud beauty! T' wood parts are all high quality Baltic birch plywood with no patches or knots in t' veneer. Arrr!
T' nosecone is a nice lookin' fiberglass component that appears t' have been laid up in a two piece mold. Avast, me proud beauty! The seam where t' two halves come together bulges slightly on one side.
Lookin' toward a bright light from inside t' nosecone, ya bilge rat, one can see where t' seam passes more light. Ya scallywag! Blimey! T' photo below demonstrates that. Aye aye! Well, blow me down! Blimey! T' material seems heavy enough, me hearties, but coarse on t' inside. Ya scallywag! After workin' in t' inside o' the nose cone t' epoxy in t' bulk plate me arms were very itchy from contact with t' rough glass fibers that are exposed. However, for t' price o' t' kit this is a huge nosecone, standin' 32-1/2 inches from t' bottom o' t' shoulder to the tip o' t' nosecone. Ya scallywag! Blimey! Blimey! It is nay coated with a glossy gel coat, me hearties, but rather with a matte finish which actually will make it easier t' prime and paint. Avast! Avast, arrr, me proud beauty! Blimey!
T' cardboard used for t' dual deployment bay coupler is a decent grade o' cardboard. Begad! It could be slightly heavier, me bucko, but it will be adequate. Begad! After a trial flight I might want t' glass t' inside o' t' bay, but I will try it stock at first. Ahoy!
Synopsis
This rocket is a nicely made kit that assembles easily. Avast! Ahoy! T' fit and finish o' t' fins, ya bilge rat, ya bilge rat, fin slots and centering rings made it fun t' build. Avast, me proud beauty! T' things that bothered me were very slight and easily remedied so I would happily buy another kit from Polecat Aerospace. Avast, me proud beauty! Our first launch here in Montana is in April and I'm eager t' fly this rocket. Ahoy!
Flight
Well, me hearties, I never did get around t' reinforcin' t' avionics bay, but it does nay seem t' need it. Well, blow me down! I have flown it twice now and it flies great on a J or a K. Avast! Ya scallywag! Blimey! It went t' 4943 on a K550, and flew straight while doin' so. Begad! Blimey! On both flights t' shear pins sheared at apogee so I need t' either use larger pins (3/32 inch round styrene right now, me bucko, but may become nylon 4/40 screws soon). Ahoy!
I painted it traditionally, with one yellow and three flourescent red fins. Ahoy! Begad!
I flew it again on a Loki Research K-350 moon burner. Aye aye! It went t' 7,738 feet. Ya scallywag!
Brief: This is a nice kit, lightly glassed with pre-cut fin slots. The fiberglass was very easy to sand and prime. Great scale kit!!! Construction: I bought the dual deploy version with a glassed coupler. A small upper payload section, lower BT and a large fiberglass NC. Total length of 76". My cone was a little weak but I added more glass and it is fine now. Great ...
This rocket is a single staged high power rocket. I have flown it on 2 different I motors and it flew both times straight as an arrow. It has a 60" parachute. It was a simple build. This rocket came with a 44 inch long body tube and a 29" fiberglass nosecone. The body tube came pre-glassed, which saved me a lot of work. Also, the fiberglassing was done very professionally. It came with 4 ...
