Brief:
This a scratch built spaceship rocket designed for t' 2009 Design-A-Spaceship contest. Blimey! Well, ya bilge rat, blow me down! It is constructed o' 110lb cardstock and presentation board.

Construction:
T' parts include:

• BT-50 for t' internal tube/motor mount
• screw eye
• presentation board for centerin' rings, arrr, fins, arrr, and bulkhead
• ¼" elastic shock cord
• 1" plastic streamer
• 1/8" launch lug
• 110lb cardstock
• clay for nose weight
• 1 BT-50 size centerin' ring
• motor block for BT-50 tube
• 1-½" long coupler t' fit into BT-50 tube (can make from BT-50 tube)

I first cut t' centerin' rings, arrr, bulkhead, ya bilge rat, ya bilge rat, and fins from t' presentation board. Next I cut t' BT-50 to 4-½". I used an online transition template t' print out t' templates for t' nose cone, ya bilge rat, body, and tail cone. Ahoy! For t' larger centerin' rings, I used t' template printout from RockSim. For t' bulkhead, ya bilge rat, 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. After they dried, ya bilge rat, I dry fit t' paper sections onto t' centerin' rings sandin' as necessary. Begad! Blimey! Well, blow me down! Blimey!

Next, me hearties, 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. Avast! After that had set, matey, I glued t' centerin' rings onto t' body tube: the smallest rin' ¼" below t' top o' t' tube, arrr, matey, 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. Ya scallywag! Avast! Then I added t' transition t' the bottom again makin' sure t' piece was perfectly straight on t' lower middle rin' and bottommost ring. I let it thoroughly dry.

T' finish t' nose cone, I glued t' coupler onto t' nose cone bein' careful t' get it straight. Avast, me proud beauty! Blimey! When it was dry, I filled t' cone with clay leavin' a ¼" lip t' t' edge. Begad! Blimey! Aye aye! Blimey! Glued t' bulkhead into t' coupler. Avast, me proud beauty! Blimey! Blimey! Blimey! When all be dry, I added t' screw eye for shock cord attachment.

As this is a tricky design, I glued t' launch lug t' a fin makin' sure it was straight.

T' shock cord is mounted in t' Estes fashion with t' other end tied t' t' screw eye. Well, blow me down! Ahoy! T' streamer is tied on about 1/3 from t' nose cone.

Finishing:
Since I used color cardstock, I didn't really need t' paint anything. 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. Avast, me proud beauty! Ya scallywag! Blimey! T' first flight be unstable. For t' second flight, ya bilge rat, shiver me timbers, I used a spacer t' extend t' motor out t' back ½". Begad! Arrr! Blimey! This caused t' rocket t' be even more unstable. Arrr! Ya scallywag! Blimey! T' third flight was a recreation o' t' first.

Recovery:
Recovery for all flights was after t' rocket hit t' ground. Aye aye! Avast, me proud beauty! 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 was nay stable. Arrr! It be a fun and interestin' build.
