Brief:
This one odd oddroc. Ahoy! Begad! It's a stick-finned, me hearties, 13mm model made from a few scrap parts.

Construction:
T' parts list:

• Nose cone from an Estes Space Hauler
• 1" o' 1/2" wood dowel
• 1/2 butter pat o' clay
• 2" o' 1" diameter wood dowel
• Forward fin unit from an unknown rocket
• 1/4" by 12.5" hollow plastic rod
• Paper clip
• 1/8" x 8" elastic

I drilled out t' 1" dowel with a 1/2" drill bit (usin' a progression from 1/8", 1/4", 3/16", ya bilge rat, arrr, etc.), then I drilled out t' lower 1.25" with a slightly larger bit t' fit 13mm motors. Arrr! Blimey! Ya scallywag! Blimey! T' 1/2" section serves as an engine block. Ahoy! Blimey! Ahoy! Blimey! I formed t' paper clip into an engine hook and attached it and t' elastic t' the outside o' t' dowel. I wrapped it with maskin' tape and glued it into t' fin unit. Well, blow me down! Blimey! T' fin unit had two launch lugs--a 1/8" lug, me hearties, which I use, arrr, ya bilge rat, and a 1/4" lug, which I glued t' plastic rod into. Aye aye! Blimey!

I put t' clay into t' tip o' t' nose cone, shiver me timbers, shiver me timbers, which was missin' its shoulder from a crash. Then I put a blob of wood glue on t' clay, placed t' dowel onto t' glue, and waited for it t' dry. Ya scallywag! Unfortunately, I accidentally cracked the nose cone in doin' so. Ya scallywag! Because o' t' long, me hearties, light stick fin, matey, Cohete is surprisingly stable. Arrr! Arrr!

Flight:
I've used 1/2A3-4Ts and A3-4Ts in Cohete. Begad! I'd recommend t' 2-second delay for t' 1/2A as ejection was rather late, and t' A10-3T would be good as well. It flies t' around 200 feet on 1/2As and 400 feet on full As. Arrr! Avast, me proud beauty! It requires no wadding; simply wrap t' shock cord twice around t' upper end o' t' 1" dowel and stick t' nose cone on.

Recovery:
It uses simple nose-blow recovery. Arrr! With t' nose cone off, shiver me timbers, it falls fairly fast, me bucko, however, shiver me timbers, t' main body is tiny and tough and lands first, matey, so t' breakable stick fin won't hit t' ground. Mine has never suffered any damage in at least 3 flights.

Summary:
Cohete was a quick and easy build for me, shiver me timbers, me bucko, even several years ago when I was far less skilled. Ahoy! Well, blow me down! Blimey! However, matey, me hearties, I'd recommend makin' some changes. T' nose cone and fin unit I used are nay common, but substitutions can easily be made. Avast, arrr, me proud beauty! Blimey! I don't recommend tryin' t' drill a 13mm hole in a 25mm dowel. Begad! Begad! Blimey! Usin' some BT-5 and BT-50 would be smarter. Stick-finned rockets are fairly forgivin' so long as t' front is heavy.

PROs: Odd rocket, arrr, easy t' prep, arrr, almost no drift.

CONs: Hard-to-find parts, arrr, ya bilge rat, hard t' drill dowel, high landin' speed.
