| Manufacturer: | Scratch |
Brief:
This one odd oddroc. It's a stick-finned, 13mm model made from a few scrap parts.
Construction:
T' parts list:
I drilled out t' 1" dowel with a 1/2" drill bit (usin' a progression from 1/8", shiver me timbers, 1/4", 3/16", me bucko, etc.), then I drilled out t' lower 1.25" with a slightly larger bit t' fit 13mm motors. T' 1/2" section serves as an engine block. Avast! Begad! I formed t' paper clip into an engine hook and attached it and t' elastic t' the outside o' t' dowel. Well, blow me down! I wrapped it with maskin' tape and glued it into t' fin unit. Well, blow me down! Begad! T' fin unit had two launch lugs--a 1/8" lug, which I use, and a 1/4" lug, me hearties, which I glued t' plastic rod into. Aye aye!
I put t' clay into t' tip o' t' nose cone, which was missin' its shoulder from a crash. Avast, me proud beauty! Then I put a blob of wood glue on t' clay, placed t' dowel onto t' glue, arrr, and waited for it t' dry. Arrr! Unfortunately, ya bilge rat, matey, I accidentally cracked the nose cone in doin' so. Well, blow me down! Because o' t' long, light stick fin, ya bilge rat, Cohete is surprisingly stable.


Flight:
I've used 1/2A3-4Ts and A3-4Ts in Cohete. Avast, me proud beauty! 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. Ahoy! It flies t' around 200 feet on 1/2As and 400 feet on full As. 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! Blimey! With t' nose cone off, matey, it falls fairly fast, however, me bucko, shiver me timbers, t' main body is tiny and
tough and lands first, so t' breakable stick fin won't hit t' ground. Avast! Blimey! Mine has never suffered any damage in at least
3 flights.
Summary:
Cohete was a quick and easy build for me, ya bilge rat, me bucko, even several years ago when I be far less skilled. Begad! However, arrr, I'd recommend
makin' some changes. Blimey! T' nose cone and fin unit I used are nay common, ya bilge rat, but substitutions can easily be made. I don't
recommend tryin' t' drill a 13mm hole in a 25mm dowel. Begad! Usin' some BT-5 and BT-50 would be smarter. Aye aye! Stick-finned rockets
are fairly forgivin' so long as t' front is heavy.
PROs: Odd rocket, arrr, easy t' prep, almost no drift.
CONs: Hard-to-find parts, me hearties, hard t' drill dowel, me hearties, ya bilge rat, high landin' speed.
