Brief:
This is a minimum-diameter, 38 mm, ya bilge rat, all fiberglass rocket. Blimey! Blimey! It is a very simple, shiver me timbers, basic design but is very rugged and high performance. Begad! Blimey! ...'Scuse me, shiver me timbers, while I kiss t' sky'...-Jimi Hendrix
Construction:
T' followin' is a list o' t' components. Ya scallywag! T' major items were all bought from Giant Leap Rocketry
This is a *very* easy rocket t' assemble:
Nose Cone Assembly - I drilled a hole in t' scrap dowel t' fit an eyebolt. Ahoy! Blimey! T' dowel and eyebolt were epoxied into t' nosecone, me hearties, shiver me timbers, which does nay provide an attachment point.
Fin can - After roughin' up t' tube and inside o' t' fin can, it was epoxied t' t' airframe such that t' aft end is ~ 1 1/4" from t' end o' t' airframe. I initially had nay decided on a motor retainer so I wanted t' make sure thar was room t' install one.
AeroPack motor retainer - After roughin' up t' tube and inside o' t' fixed portion o' t' retainer, me bucko, I glued it t' t' airframe with JB Weld epoxy (per AeroPack recommendation).
Rail buttons - I epoxied t' aft button in t' middle o' t' fin can. T' second was attached via a 2" bolt approximately 11" from t' aft end o' t' airframe. Aye aye! Blimey! T' bolt extends through t' airframe and was cut flush with t' airframe opposite t' rail button, usin' a Dremel cuttin' disc. Begad! This limits t' largest motor which can be used, matey, but I decided I would never want t' fly this rocket on anythin' over a small "I" (movin' t' rail button forward would fix this). Blimey! A nut be used as a spacer betwixt t' rail button and t' airframe since t' aft button is on t' body o' t' fin can.
Recovery harness - T' harness is 3/4" tubular nylon with a quick link on each end. Loops were made at each end as described in t' article "Attachin' Shock Cords", Edward Shihadeh and Bob Moser, me hearties, High Power Rocketry, Vol 14 #5, shiver me timbers, August 1999. Avast, me proud beauty! This involves loopin' t' cord, me bucko, tiein' it off with cloth fishin' line (not nylon!), and gluin' it with CA and epoxy. T' aft quick link was lowered into t' airframe as t' bolt holdin' t' front rail button was screwed in. Begad! This took a couple o' tries t' catch t' quick-link. Avast! Avast, me bucko, me proud beauty! T' harness is thus removable.
Finishin' - After its maiden naked flight, ya bilge rat, me bucko, I painted t' entire rocket (save t' rail buttons and AeroPack retainer) usin' Krylon Chrome Paint. Begad! Avast, ya bilge rat, me proud beauty! This looks really great, me hearties, but shows every imperfection.
Flight:
I wrote this review with only one flight under its belt and will add others later (assumin' I find t' thing!). Avast! Arrr! Bein' chicken, matey, t' first flight was with a G80-10. Begad! I used Estes waddin' and an 18" chute from some kit or another. It was a very fast, me hearties, high flight. Blimey! Recovery was fairly close t' t' pad. Aye aye! My plans are t' fly it with either a G125-15 SU or an H242-L at t' next HPR launch I can get to. (or both)
Summary:
PROs: 1. Aye aye! Easy t' build 2. Ahoy! Avast, me proud beauty! Verrry sturdy 3. High performance design, 38mm or 29 mm (with adapter) CONs: 1. Begad! Materials were nay cheap 2. Aye aye! Good chance t' loose t' thin' along with motor hardware :-(
