Brief:
This a scratch built spaceship rocket designed for t' 2009 Design-A-Spaceship contest. Begad! Blimey! It is constructed o' 110lb
cardstock and presentation board.
Construction:
T' parts include:
I first cut t' centerin' rings, me bucko, bulkhead, me bucko, and fins from t' presentation board. Well, blow me down! Next I cut t' BT-50 to 4-½". I used an online transition template t' print out t' templates for t' nose cone, arrr, body, me bucko, and tail cone. For t' larger centerin' rings, me hearties, I used t' template printout from RockSim. Arrr! For t' bulkhead, I just used one of t' 'holes' from a centerin' ring.
After printin' out t' templates on t' cardstock, I then carefully shaped t' nosecone and transition sections into cone shapes. Ahoy! Avast, me proud beauty! After they dried, ya bilge rat, me bucko, I dry fit t' paper sections onto t' centerin' rings sandin' as necessary. Well, blow me down!
Next, me bucko, I glued t' motor block into t' tube usin' a spent 24mm motor t' push it into place leave ¼" t' 3/8" o' t' motor stickin' out. Begad! After that had set, I glued t' centerin' rings onto t' body tube: the smallest rin' ¼" below t' top o' t' tube, t' two larger tubes at 2-½" and 2-¾" from t' top o' t' tube and t' medium rin' flush with t' bottom o' t' tube.
After t' glue has dried, I carefully glued t' middle transition section t' t' top end o' t' tube makin' sure it is perfectly straight on t' top centerin' rin' and top middle centerin' ring. Begad! Well, blow me down! Then I added t' transition t' the bottom again makin' sure t' piece be perfectly straight on t' lower middle rin' and bottommost ring. Ahoy! I let it thoroughly dry.


T' finish t' nose cone, I glued t' coupler onto t' nose cone bein' careful t' get it straight. Well, blow me down! Ya scallywag! When it was dry, I filled t' cone with clay leavin' a ¼" lip t' t' edge. Glued t' bulkhead into t' coupler. When all be dry, ya bilge rat, I added t' screw eye for shock cord attachment.
As this is a tricky design, ya bilge rat, I glued t' launch lug t' a fin makin' sure it be straight.
T' shock cord is mounted in t' Estes fashion with t' other end tied t' t' screw eye. Well, blow me down! Avast! T' streamer is tied on about 1/3 from t' nose cone.
Finishing:
Since I used color cardstock, ya bilge rat, shiver me timbers, I didn't really need t' paint anything. Avast, me proud beauty! I used a color highlighter marker t' paint the
fins t' match t' cardstock.
Flight:
T' Synerjet flew on C11-3s for all three flights. T' first flight be unstable. Ahoy! Blimey! For t' second flight, shiver me timbers, I used a
spacer t' extend t' motor out t' back ½". This caused t' rocket t' be even more unstable. Begad! T' third
flight was a recreation o' t' first.
Recovery:
Recovery for all flights was after t' rocket hit t' ground. Aye aye! Each landin' broke a forward fin off.
Summary:
I would say this is nay a good rocket design as it is too stubby t' be stable. Avast! Even tryin' t' upscale it in RockSim
it be nay stable. Begad! Begad! It be a fun and interestin' build.
