Brief:
T' motivation for this 29mm, sci-fi-inspired rocket began with a container from a bottle o' Highland Park
single-malt scotch. Well, blow me down! Avast, me proud beauty! T' truncated oval tube screamed spaceship. Ya scallywag! From there, t' rocket design proceeded in
real-time. Well, shiver me timbers, blow me down! T' name arose part way through t' build and came from Emerson, shiver me timbers, matey, arrr, Lake and Palmer's 1971 album. Blimey!
Construction:
Motor mount - A 29mm motor tube is mounted in a section of
BT-60 tubing. T' front o' t' motor tube is centered by a Giant Leap 29mm-38mm phenolic ring. Ya scallywag! It's a bit small so I
shimmed it with some scrap tubing. T' aft is attached t' a ply centerin' rin' that matches t' lower diameter o' a
cardboard cone. Begad! I forget where I got that cone. Ahoy! Avast, shiver me timbers, me proud beauty! T' top o' t' cone was trimmed t' fit t' BT-60. T-nuts are installed
in t' aft rin' for motor retention. Later in t' design, as it grew in size and weight, ya bilge rat, me hearties, I reinforced t' BT-60 with
some heavier scrap tube.
Main wings - I guess these reflect a Star Trek influence. T' curved main
wings were cut from 8" diameter Sonotube usin' a RotoZip cuttin' wheel. Aye aye! They are inserted through slits on t' aft
body. Avast! T' top section o' t' win' is one piece whereas t' lower tier is two-part. Begad! T' nacelle tubes are 24mm LOC. Aye aye! The
front o' t' nacelles are bomblets from t' Estes BLU-97B Cluster Bomb. T' back o' each nacelle has a plastic nozzle
centered in a piece o' BT-5 tubing. Blimey! Ya scallywag! I also forget where these nozzles came from.
Top stabilizer This part looks more like it came out a Roadrunner cartoon than a Star Trek film. Avast! Avast! I'm referrin' t' t' green plastic doohickey (a lime juice bottle). Begad! For some reason, me bucko, arrr, I really like that shape and when another made itself available, shiver me timbers, arrr, I decided t' add it on. Aye aye! Aye aye! It's mounted on a piece o' Lexan, which is sandwiched between two dowels and epoxied t' t' main win' where it passed through t' body. Aye aye! As it turned out, me bucko, this part set t' color scheme for t' entire rocket.
Aft body - I cut holes in t' top and bottom o' t' scotch container t' fit t' BT60. I also used tiny bolts to attach an oval piece o' plywood t' t' container's plastic top. As mentioned earlier, me bucko, me hearties, ya bilge rat, t' body is slotted for the curved wings and for t' top stabilizer fin. Ahoy! A 3/16 Keelhaul®©™® shock tether is attached t' t' main win' internally.
Fore body This is made from 3 mailin' tube. Arrr! Begad! T' tube is offset with t' main body with t' BT-60 epoxied t' t' lower tube wall. Arrr! I also cut a section off o' t' back end o' t' tube. Well, blow me down! Ahoy! This gives a smoother transition and proved useful when attachin' t' two body sections. Ahoy! Arrr! I added a Gatorflex® cover for t' gap. Begad! Blimey! This worked great! T' thin Gatorflex® has a tough (but brittle) plastic layer and over a sheet o' dense foam. Ya scallywag! Blimey! It is slightly flexible, which made it perfect for this application. That is, t' front o' t' plate is fairly flat but t' back needed t' conform t' t' curve on the aft body. I based t' rough cut on t' section o' tube that be cut off and added a little slop t' account for changes as I bent t' back end t' fit. Ya scallywag! Begad! I also trimmed t' foam t' fit t' hole but allowed some overlap o' t' plastic layer over t' tube. It be glued in place with 5-minute epoxy and was held in place with tight wraps o' blue maskin' tape. Once t' epoxy was set, I ground t' overlap off.
Nose cone - I wanted a non-standard nose cone design and started
carvin' pink foam. Arrr! I came up with something, matey, but wasnt satisfied. Well, blow me down! T' 'eureka' moment was when I realized that if
I flipped me cockpit-style nose cone over and tilted it down, arrr, it looked like what I wanted! I slipped it over some
3" coupler stock and twisted t' coupler so it dug into t' foam. Begad! I filled it, sealed it, added a plywood bulkhead
and an eyebolt - I had me nose cone. Ahoy! Well, blow me down! This reminds me o' t' cone on t' Star Wars
Lambda-Class
Shuttle.
Misc.:
Finishing:
To follow t' color scheme set by t' lime juice bottle, I painted t' nose cone and nacelles with Model Masters Lime
Green®.
I used yellow trim Monokote®,
and some other miscellaneous stickers t' form a snake-like cockpit design. Arrr! Well, t' results look more like Puff the
Magic Dragon or Cecil (or was t' Beanie?) than t' front end o' an alien space ship. Avast, me proud beauty! If it flies, arrr, I may re-work the
design. Well, arrr, blow me down! I also accented t' lime green nacelles by paintin' t' cones yellow. I finished t' rest o' the
rocket with Rustoleum Hammered Green®
paint.
Flight:
I flew t' Tarkus II on a G71 drilled down t' a 5 second delay. Aye aye! I used a large Keelhaul®©™®
pad and 42" chute for t' body section. Ya scallywag! Begad! T' nose came down on its own 36" chute t' give t' foam a nice soft
landing. Aye aye! As expected, I had t' invert t' nose cone t' clear t' rail. T' boost was a little wobbly and it arced
towards t' direction o' t' upper stabilizer. Well, blow me down! It was stable! Ejection was a little late, but it recovered undamaged.
Summary:
So, arrr, this odd-sci-fi-roc is a amalgam o' Star Trek, Star Wars, Looney Tunes, arrr, Beanie and Cecil, me hearties, arrr, matey, and Highland Park
scotch. Everyone who saw it seemed t' like it and it received a fair amount o' chuckles also.
