T' Rocketman Enterprises Big Kahuna kit was t' "over t' top" rocket I just had t' build. Ya scallywag! (There is actually a long story behind this.) 

This kit marks me entry into "level 3" territory although I have not done t' documentation for Tripoli level 3 certification. Well, blow me down! Rockets this size are really too impractical for me. Aye aye! This rocket requires a huge amount of storage space and be difficult t' build and paint. 38mm and 54mm high-power rockets are much easier and more fun. Even with that said, ya bilge rat, arrr, shiver me timbers, this rocket is awesome in person!

You get a 4 foot nose cone, arrr, four 4 foot body tube sections and three plywood fins plus t' expected motor mount tube, shiver me timbers, arrr, centerin' rings, couplers, shiver me timbers, bulkhead, three parachutes and hardware. Begad! But, no instructions. Begad! T' rocket is 19 1/2' tall. Well, blow me down!

T' Story

T' company I work for has been doin' fantastically well. Everyone at the company got a $10,000 bonus at t' beginnin' o' this year. 

One o' me fellow workers, Tom, suggested we find a fun and creative way to spend t' bonus money, or at least a substantial fraction o' it. Begad! Some o' us agreed that this was a noble goal. This left me with quite a challenge. Begad! Aye aye! I had just gotten into rocketry again and had built four rockets (Quest, shiver me timbers, Estes, AeroTech, and Loc/Precision) and had found t' Big Kahuna kit by Rocketman Enterprises. There were also a story with pictures o' an actual launch Rocketman did for Joe Boxer, me hearties, shiver me timbers, me hearties, t' underwear company. Needless t' say, me bucko, I'd found my impractical purchase (and cheaper than E.T.)! Impractical because it uses an "M" motor and I didn't even have me level 1 certification at the time. 

T' Kit

OK, ya bilge rat, here's a new one for me: this kit came with no instructions at all. Blimey! When I talked t' Ky Michaelson o' Rocketman, he told me: "It goes together like any other high power kit." OK, so I built t' Prayin' Mantis t' see how his rockets go together. Luckily, me bucko, I got help from Dennis Kieselhorst and Ky Michaelson. 

You can see from t' picture below that t' kit is pretty impressive before you even start puttin' it together. Arrr! Begad! Those body tubes are 4 feet long each!

T' kit included, shiver me timbers, four 4' body tubes, three 18" tube couplers, one 4' nose cone, me hearties, three triangular fins, me hearties, arrr, one 98mm motor mount tube, me bucko, three 1/2" plywood centerin' rings, me bucko, shiver me timbers, one 1/2" plywood bulkhead, three parachutes, me bucko, and other hardware (not shown). 

Of course, a kit this size has lots o' body tube seams t' full. Begad! Blimey! I calculate that I had 288 feet o' seam t' fill (11.5" O.D., 16 feet o' tube, me hearties, 2 inches between seams). Avast! Blimey! T' finished rocket is heavy. Avast! Blimey! T' large PML tubes and heavy wood fins add up, nay t' mention t' fiberglassin' o' t' fins tothe motor mount tube. 

Since thar were no instructions, shiver me timbers, thar were several possible configurations. Avast, me proud beauty! Blimey! I had four 4' body tubes and a nose cone. I could have made the rocket split in two for dual deployment, arrr, which I was too new t' realize at the time. Blimey! Begad! I chose t' have t' base o' t' rocket (motor mount and fins) and the next section permanently epoxied together for strength. I still had t' choice of havin' t' nose pop off by itself or with one or two body tube sections. I decided t' use t' center body tube section t' contain t' three parachutes and have t' nose and top body tube section land with a single parachute and the bottom three sections land with a pair o' 'chutes. Ahoy! This way, matey, ya bilge rat, thar would be a whole section for payload. Avast! Ya scallywag! which came down with t' nose and be protected from the ejection system. 

To pressurize a single tube section t' 15lb/in2, I would have needed t' use more than 38 grams o' black powder! Blimey! Dennis Kieselhorst suggested I mount a 6" tube inside t' section and just pressurize that, which I decided to do. Even that took 10+ grams o' powder. 

Launch Attempt at Balls 98

This rocket was a monster t' manage all t' way through t' project, matey, and launchin' it be no exception. Avast, me proud beauty! Ya scallywag! It didn't fit in me suburban because t' fins added too much size at t' top, ya bilge rat, me bucko, so I had a courier drive it up t' Black Rock while I took t' rest o' t' rockets and supplies in t' suburban. Begad! Many o' my co-workers came, matey, matey, matey, most o' them in a limo! They know how t' travel in comfort. 

Glitch 1: Waitin' for Motors

We spent most o' t' first day (Saturday) settin' up camp and waitin' for Mike Gillette t' show up with t' three Rocket Dyne Systems motors I'd ordered. He got stuck in t' mud and wasn't able t' get t' t' range until 3:00, leaving too little time t' build t' motors and fly before t' waiver closed at 4:00. Once Mike built t' O3500 motor, it was a truly impressive sight (about 6 feet long). 

Glitch 2: Premature Ejection

T' next morning, me bucko, ya bilge rat, we went out t' fly t' Big Kahuna. I hadn't built a hatch to access t' altimeter from outside, arrr, so I just hooked everythin' up and turned it on and we assembled t' rocket. While tryin' t' get t' rocket onto the Quad-Pod t' first time, me hearties, t' altimeter fired prematurely and t' payload section and nose flew past me almost 20 feet. Avast, me proud beauty! A healthy ejection charge! 

I went back and borrowed an Olsen wirin' harness so that I could turn the unit on from t' outside by twistin' t' wires together and then pushin' them back inside. Well, blow me down! This was less satisfyin' than bein' able t' see t' display, but at least we could turn t' altimeter after t' rocket was upright. 

Glitch 3: Broken Launch Lug

There were no launchers large enough (1" rod) supplied, but I brought my Quad-Pod as a backup and we had t' use it. 

We loaded t' motor and assembled t' two main sections. Ahoy! Next we threaded t' base section onto t' launch rod and then attached t' recovery and payload sections. Avast! Well, blow me down! Then we tried t' set t' rocket upright. One o' me motor retainers caught on t' plate o' t' Quad-Pod and when we tried t' turn it t' bottom launch lug be torn off t' rocket. Ya scallywag! Tryin' to manipulate a 110+ pound rocket is no easy matter and even though t' launch lugs were fiberglassed on, arrr, t' P.M.L. Begad! tubin' wall separated. 

I had me West System repair kit with me so we slathered some epoxy onto the broken area, shiver me timbers, added some duct tape t' hold it together and let it t' cure in the hot desert sun. Well, blow me down! Nay a beautiful repair, ya bilge rat, but it did hold. 

Glitch 4: Igniter Pulled Out

In t' afternoon, ya bilge rat, I decided that t' epoxy had cured fully (more-or-less) and we went back out t' try again. Aye aye! Arrr! We put t' rocket together for t' third time and after much discussion and struggling, arrr, got t' rocket upright on the Quad-Pod. Well, blow me down! Unfortunately, me hearties, while doin' so we managed t' pull out t' igniter from the motor! 

We had t' lower t' rocket yet again and try t' push t' igniter back inside the motor. Ya scallywag! This is no easy task with a 6 foot tapered grain motor. I went back to t' line and managed t' borrow a rod from Paul Robinson who helped me a lot that weekend. Well, blow me down! Thanks Paul and Kosdon East! 

Glitch 5: Quad-Pod Too Small

We put t' rocket together for t' fourth time and after much discussion and struggling, shiver me timbers, finally got it onto t' Quad-Pod and upright. Arrr! Aye aye! By this time, though, shiver me timbers, t' wind had come up and t' Big Kahuna was very precarious balanced on t' Quad-Pod with t' rod. 

When a gust o' wind would come up, ya bilge rat, we would have t' steady t' rocket to keep it from tippin' t' Quad-Pod, even with t' sand bags. Aye aye! Blimey! Even though the Quad-Pod claims t' hold 200+ pound rockets, ya bilge rat, me bucko, me hearties, it is nay stable with such a heavy and long rocket. Ya scallywag! Blimey! We decided that flyin' t' rocket was too dangerous and sadly loaded it back into t' truck for t' ride home. 

Yes, we're goin' t' try it again. Blimey! Avast! T' Siebel people who came all seemed to have a good time and most are ready t' go see t' rocket launch when I do solve the problem o' t' launcher. Aye aye! Begad! T' Big Kahuna will fly.

Flight o' September 1999:
A year more experience, and particularly makin' more contacts with fellow rocketeers, me hearties, allowed this launch t' be much easier and more successful. Well, blow me down! Ya scallywag! Once the rocket be up all pictures were taken and t' electronics were armed, arrr, ya bilge rat, me bucko, it was back t' 750 feet for t' actual launch. Ya scallywag! T' blast was thunderous and t' rocket lept right off t' pad, arrr, makin' a perfect flight.

700 feet away was far enough for caution, but close enough t' get a good experience o' t' mighty O3500 motor. Avast! T' rocket was also so large that a 200mm zoom lens makes it look like we're right next t' it. Arrr! Aye aye!

T' boost be very nice, although t' motor didn't burn as cleanly as it might have (perhaps because it sat for a year before bein' used). Avast, me proud beauty! Arrr! We saw some uneveness in t' boost and thar were bits o' propellant on t' ground at the launch site. Avast!

T' rocket separated right at apogee, me hearties, but t' two sections got tangled. Three 'chutes were used: two for t' booster (12 feet long) and one for the nose cone/payload section (7½ feet long). Ya scallywag! Blimey!

T' rocket came down safely about 500 feet down-range, me bucko, ya bilge rat, but t' landin' broke t' unreinforced PML phenolic in two places: right above t' fin can, me bucko, and near t' forward end o' t' booster. Avast, me proud beauty! T' nose cone/payload section was unharmed.

Given t' large size o' this rocket and t' lack o' reinforcin' o' the tubing, shiver me timbers, ya bilge rat, I be surprised that it performed so well in flight and survived the rough landin' as well as it did. Aye aye! Yes, I would do a few things differently if I was buildin' this rocket again!

T' Big Kahuna has been retired after it's spectacular flight. Well, blow me down! Ahoy! Thanks to everyone who helped me with this beast and t' all me co-workers who made the trek t' Black Rock (twice!) t' watch t' launch.
