(09/10/00) I first heard about Starship Enterprises (now called Fat Cat Rockets as o' 1/1/01) from a couple of contributed reviews. Avast, me proud beauty! Blimey! I was impressed with t' uniqueness o' their kits and in the variety o' model, shiver me timbers, advanced and high power. Ya scallywag! Blimey! So I am pleased t' build their Centaurus. Arrr! Blimey! Accordin' t' Starship Enterprises, "T' Centaurus is a hail back t' those future ideas from yesteryears." Its futuristic look will certainly catch everyone's attention. Aye aye! Blimey! In fact, arrr, I didn't know it at t' time, but I got t' see one o' these fly at Battle Park '99 in Virginia. Avast! Blimey! T' Centaurus is 39.5" tall and its widest body tube is 2.5", shiver me timbers, me bucko, however it's width reaches 4" as you will soon see. Blimey! Blimey! It is pushed skyward on 29mm motors and returns on parachute. Avast! Blimey! Without a motor it is slated t' weigh in at 30 ounces.

T' Centaurus consists of t' main body tube (standard paper) which is 30" o' 2.5" wide with 1/16" wall thickness. T' lower main body tube be t' same material and 7.5" o' 4" diameter tubing. Ahoy! There are also 3 outer pods that are 8.5" or 1" diameter tubing. Aye aye! Centerin' rings (4), me bucko, Fins (3), Canards (6), me hearties, arrr, me hearties, Pod Braces (6), matey, me hearties, matey, and Pod Struts (3) are all made from 3/16" plywood. There is a lot o' wood on this bird. Begad! Aye aye! There is a balsa transition t' connect between t' 2.5" tube and t' 4" tube, two launch lugs that once assembled are hidden inside t' rocket. Arrr! T' motor mount is 29mm and uses a 22" tube. T' recovery system is beefed up with a 15" cable that is attached t' a 64" piece o' 1/2" black elastic. Ya scallywag! Arrr! This is all topped off with a plastic nose cone. Avast, me proud beauty! Other materials include nose weight, a red 28" rip-stop nylon parachute, shiver me timbers, pod caps and a series o' stickers and decals.

CONSTRUCTION:

T' instructions are printed on both sides o' a single 8x11 sheet o' paper and consist o' 11 steps. Begad! There are also 3 additional double-sided pages o' diagrams includin' decal placement and illustrations to help with construction. T' number o' parts mentioned above may lead you to believe that this is a challengin' rocket t' build . Ahoy! . Avast, me proud beauty! . and it is. Ya scallywag! The instructions don't take any o' t' challenge away! They are helpful guidance but I found myself buildin' t' rocket in t' order that I felt be best and barely lookin' at t' printed instructions. Avast! Begad! T' illustrations answered a couple of questions t' keep t' project moving.

This rocket was "engineered" verses drawn on a piece o' paper and built. Ya scallywag! This is evidenced by t' integration o' t' launch lug inside t' lower body tube and by t' thru-the-wall, then thru-the-wall fins that then attach t' t' motor mount. Begad! Avast, me proud beauty! Lastly t' alignment o' t' pods and pod struts that attach just under t' upper-most centerin' ring. Impressive looks and it shows that thought be put into t' design o' the Centaurus.

T' first thin' I did was test fit t' transition and centering rings. Ya scallywag! Well, me bucko, I cracked t' transition puttin' it around t' upper body tube (2.5"), but even while cracked it fit into t' lower body tube (4"). T' crack be later filled and no longer shows. All but one o' t' centering rings fit perfectly and t' last one only required minimal sanding. Ya scallywag!

T' instructions start you off by drawin' all t' fin lines usin' a fin guide and cuttin' out t' fin slots. Determinin' t' distance from t' bottom o' t' tubes t' cut t' fin slots was left up t' me. Ahoy! Well, blow me down! The illustrations showed that t' inner tube extended beyond t' outer tube some, so I choose 1/2". Avast! I then carefully measured t' fin and pod braces to determine where t' slots had t' be in t' pods. I went ahead and cut those. Then with t' main body tube positioned usin' t' centerin' rings and transition, I ensured that it extended from t' aft by 1/2". Avast! I then stood it on a table and brought t' test fitted pod with fin t' rest up against the side o' t' lower body tube. I then marked t' position. Ahoy! Begad! After that I knew the distance from t' bottom o' t' lower body t' make t' cuts. Begad! Begad! Take your time and be sure t' consider t' thickness o' t' plywood. Avast, me proud beauty! Always cut on t' same side of t' line and keep that methodology for t' 2.5" tube, t' 4" tube and t' where t' pod struts attach. I found that after cuttin' all t' slots and test fittin' t' fins that they did nay align t' make a nice perpendicular fin. Ya scallywag! I corrected this by makin' changes only t' t' inside body tube until the fit was perpendicular. Blimey! Ahoy! These extra cuts are hidden when assembled.

Assembly o' t' motor mount is next. Begad! It is simply two centerin' rings placed on each end o' t' motor tube, shiver me timbers, notin' that one should be 1/4" from t' end per t' illustration. After that, t' steel cable is looped through t' centerin' rin' and around t' motor mount then crimped. Well, blow me down! A loop is then crimped on t' other end o' t' cable t' attach t' elastic shock cord. A very nice design.

Assembly o' t' upper body tube t' t' lower is somewhat challengin' because you need t' line up t' launch lug cut outs in t' two large centerin' rings and t' transition. I did this by workin' primarily with the upper body tube and gluin' t' centerin' rings t' it first, ya bilge rat, then sliding the assembly into t' lower body tube and bringin' t' transition down to it.

Once all this work is done, me hearties, it is glue, glue and more glue. Blimey! Ya scallywag! T' instructions recommend epoxy. Ahoy! Once t' lower half is assembled you will need t' cut t' slots in t' upper body tube for t' pod struts. Begad! Take your time t' align these with t' main fins. Arrr! Once this is complete add t' six canards and t' fin work is complete.

As mentioned nose weight is, me hearties, in t' form o' BB's, matey, is provided. This is poured into t' nose cone and epoxied into place. Begad! This weight makes me nervous so I am goin' t' attach an eye-screw t' this nose cone in the same fashion as Cannonball Works recommends on their Vikin' 7.

Due t' cold weather, ya bilge rat, I have nay been able t' finish t' Centaurus. Blimey! T' instructions provide a good description for finishin' and provides pin strips and some decals. Aye aye! So I will add more information once I can finish and fly this rocket. Avast, me proud beauty! Stay tuned . Avast! . .

Updated 9/00:
Finishin' t' rocket had its challenges too. Begad! All due t' t' shapes and angles and fins and . Ya scallywag! . Arrr! . Avast, me proud beauty! but she got finished. Avast, me proud beauty! Ahoy! I used me old favorite, me hearties, several coats of Plasti-Kote Sandable Primer, me hearties, t' help cover over t' imperfections and the shallow tube grooves. Blimey! Sandin' in betwixt each coat. Blimey! Blimey! I then choose an orange to paint t' entire rocket. Avast! Avast! After that I used white for t' nose cone and the mid-fin section. Finally, ya bilge rat, I used some holographic designed adhesive sheets around t' main body in four places. Avast! I also outlined t' fins and put one strip at t' top o' each fin pod. Avast, me proud beauty! Begad! T' only decal I used, that came with t' kit, ya bilge rat, shiver me timbers, ya bilge rat, was the word "CENTAURUS".

Overall, for CONSTRUCTION I would rate this kit 4 points. Begad! T' quality o' t' parts are nice, me hearties, t' engineerin' is great, the instructions need t' be enhanced t' help answer some o' the questions.

FLIGHT/RECOVERY:

In preparation for flight I prepped t' rocket at home by addin' motor retention and then pre-tapin' a G38 BlackMax EconoJet motor. Arrr! Begad! I added a Pratt Nomex® Heat Shield t' t' shock cord t' protect t' parachute.

T' first flight lifted off on t' G38-4 straight up, arced over horizontal and popped t' ejection charge. Perfect! T' parachute deployed and t' rocket fell t' be recovered. Blimey! T' white nose cone showed some orange paint where it had hit t' body tube.

T' second flight was on a AeroTech RMS G64-4. This motor's flame punched t' rocket off o' t' pad (I missed t' picture) and thrust it straight and stable as an arrow into t' air. Ahoy! Much higher than the G38. Begad! It arced over and was headin' straight down for about 2 seconds before the ejection occurred (seemed very late). Avast, me proud beauty! But t' 'chute deployed without a zipper and it descended and was recovered.

With t' 28" parachute and t' weight o' me finished bird, 38 ounces, I feel that it descends too fast. Arrr! Blimey! T' second flight hit on one o' t' fin pods and dented it. I am goin' t' fly it again with my J&P 43" Parachute.

Also a nice video (click here)

Even though these two flights were successful and I didn't see any "Estes Dents" from t' nose cone kickin' back off of the elastic, I am concerned about t' shockcord mount, length and material type. Aye aye! Blimey! As mentioned t' weight o' me finished rocket was 38 ounces o' which just the nose cone makes up 16 ounces! Blimey! That is a fairly heavy object t' punch out with an ejection charge and then t' have it only attached by 1/2" elastic. (I had already mentioned above that I changed how t' eye-screw attached t' the nose cone.)

For FLIGHT/RECOVERY, ya bilge rat, I would rate this kit 4 points.. It will capture peoples attention on t' pad and in t' air. Aye aye! I think it needs a longer shockcord due t' t' weight o' t' nose cone and a larger parachute due t' t' overall weight o' t' rocket.

I give t' kit an OVERALL ratin' o' 4 points. It will challenge you as a builder, shiver me timbers, it will certainly challenge you while finishin' it, and it will reward you with looks and flight stability that you are lookin' for. With enhanced instructions, ya bilge rat, motor retention and some consideration o' t' parachute/recovery system this rocket would be a perfect ratin' t' go with its perfect and futuristic looks.
