Brief:
Dos Kraken is a combination and upscale o' two unique rockets. Avast! T' design is from Pemtech's Kraken with t' sculpted tube fins and t' canted twin motor tubes design was borrowed from FlisKit's Deuce's Wild. Blimey! Begad! Dos Kraken will fly on a pair o' 38mm x 480 AT motors with t' total output o' a J sized motor. Dual deployment will be handled by a Perfect Flight MAWD and a Cannonball Works RRC2. Begad! Recovery will be dual deployment with a 24" drouge at apogee and a 72" SkyAngle at an altitude o' 500'.

Construction:
T' Booster section used 5 pieces o' 3.9 LOC airframe tubes. Well, blow me down! Avast! One tube for each sculpted tube fin and t' other for t' center o' t' booster. A LOC electronics bay with a 20" payload section completes t' rocket body. All tubes were fiberglassed usin' fiberglass sleeves from Sollar Composits and West System epoxy. Aye aye! T' two centerin' rings and gussets were cut from 1/4" birch plywood. Ya scallywag! Motor tubes are LOC 38mm x 10" long and canted at 10 deg. Avast, me proud beauty! from t' centerline. T' fiberglass nosecone and 1/4" Keelhaul®©™ shock cords are from What's Up Hobbies.

After buyin' and buildin' a Kraken from Pemtech, it be fairly easy t' use t' same destruction techniques for t' upscale. Ahoy! T' layout o' t' sculpted fins is explained very well when buildin' t' smaller version. Well, blow me down! I drew t' layout lines on t' tubes before fiberglassing. Avast! After puttin' t' sleeve over t' tubin' and t' resin is applied t' fiberglass will be transperant and very easy t' see t' markings for cuttin' and fin attachment. Aye aye! Ya scallywag! A saber saw with a fine tooth blade was used t' cut t' fiberglassed tubes leavin' a fairly clean edge.

Finishing:
I made a thick paste o' epoxy and collidal silica. I rubbed it on t' fiberglassed tubes t' fill t' exposed weave. Begad! This leaves a smooth finish that makes final finishin' less work. Paintin' is a little tricky but again t' Pemtech destructions give a couple o' tips on makin' paintin' fairly easy. Begad! Well, blow me down! Blimey! I used Rust-olium Metallic paints for a very nice metal flake finish. I had t' name and flames made by Mark Hayes o' Sticker Shock. Avast! Aye aye! He made some very nice vinyl decals that were scaled t' fit t' rocket.

Flight:
For t' maiden flight I used a pair o' Aerotech I-285 Redline's. Avast! Begad! On t' second flight, ya bilge rat, lift off was on a pair o' Aerotech I-284 White Lightnings air startin' t' a pair o' Aerotech H-112 Black Jacks. Well, blow me down! Ya scallywag! Recovery electronics are handled by a Perfect Flight MAWD and a Cannonball Works RC22 as back up. Begad! A Perfect Flight MTG3 is used for ignition o' t' sustainer motors. Aye aye! For motor retention I used some extended Kaplow type clips. Begad! T' rocket flies straight with very little rotation.

Recovery:
T' Drouge parachute is attached t' t' booster section by 5' o' 1/4" Keelhaul®©™ rope and t' booster is conected t' t' payload section by 25' o' 1/4" Keelhaul®©™ rope.

T' main parachute recovery harness consists o' 25' o' 1/4" Keelhaul®©™ rope betwixt t' nosecone and electronics bay. Begad! Ahoy! with t' paracute attached 8' from t' nosecone.

Summary:

PROs: Dos Kraken has a very unique look and draws alot o' attention with t' sculpted fin tubes. Well, blow me down! Begad! Usin' t' Deuce's Wild motor mount and t' ability t' airstart sustainer motors really adds t' t' overall fun o' t' rocket.

CONs: This is nay really a con but t' rocket takes alot more time t' prep and is more complex than a single motor rocket.
