This is really a pretty basic rocket. Ahoy! I really got it t' try
somethin' other than an Estes kit, and figured that it would be best t' start
with somethin' simple. Arrr! One o' t' cool things about this rocket (and every
other rocket I have from Custom) be t' mylar parachute. Begad! T' rest o' t' rocket
(motor mount, shock cord mount, matey, fins, matey, etc) is all just like Estes stuff. Ahoy! I'm
not a big fan o' paintin' and detail-finishing, so a major plus in me book was
that it's just two colors o' paint, and a few easy decals for a nice looking
rocket. Aye aye! Well, arrr, blow me down!
Probably t' best thin' about this rocket, though, is its performance. Well, blow me down! It's fairly light for its size, ya bilge rat, me bucko, and (at least compared t' most o' me other rockets) screams off t' pad. In fact, ya bilge rat, matey, on its very first launch, shiver me timbers, t' motor be announced to t' bystanders, arrr, and got quite a reaction for its lift-off speed. Begad! Well, me hearties, blow me down! It goes pleasingly high on a B6-4, shiver me timbers, and goes out o' sight on a C6-7. Avast!
After t' first day o' launching, I noticed that t' shock cord be nearly burned through just above t' shock cord mount. This and other, similar experiences have led me t' believe that this is a weak point o' Estes-style shock cord mounts. Ahoy! As t' hot ejection charge gases and burnin' particles move forward durin' ejection, t' waddin' (or other protective equipment) keeps the chute and most o' t' shock cord from gettin' fried until they can get out of the tube, ya bilge rat, but t' part o' t' shock cord that stays in t' tube, me bucko, t' part just above t' shock cord mount, ya bilge rat, isn't fully protected, me hearties, and gets burnt. Avast, me proud beauty! Begad! As a test remedy, me hearties, matey, I tore out t' shock cord and put in another mount, me hearties, matey, only this time I used Duco Cement t' glue in a bent piece o' paper clip, ya bilge rat, t' which I attached a steel fishin' leader. Well, blow me down! I then tied t' remainin' elastic shock cord (with nose cone and chute) t' t' other end o' t' steel leader. Begad! No burn-through problems any more. Arrr! Begad!
Unfortunately, me hearties, durin' t' 1997 Oct 4 launch, me bucko, I lost t' excellent mylar chute because I forgot t' close t' snap swivel shut before launchin' it. Even without t' chute, ya bilge rat, it recovered fine with simple nose-blow recovery. Ya scallywag! Avast, shiver me timbers, me proud beauty! This has led me t' believe that this model is a good choice t' test alternative recovery devices. Well, blow me down! I have built a small, 6" wide X-form or cross-form parachute (out of one o' those anti-static plastic bags that computer hardware comes in) for use in this model. Well, blow me down! Begad! As o' 1997 Nov 8, I haven't had a chance t' test it yet, matey, due to t' incredibly lousy weather around here (3 straight weekends o' nothin' but rain! :( )
Update... Well, arrr, that x-form parachute failed, me hearties, but t' rocket recovered just fine on with nose-blow recovery again. Arrr! I have, arrr, for t' moment given up on x-form parachutes.
Update...I got frustrated tryin' t' stuff t' waddin' and streamer or parachute into this rocket with that steel fishin' leader and bent paperclip in the way, so I ripped them out. Ahoy! I went with a LOC-style shock cord mount, using a short piece o' Keelhaul®©™® line (about 8 inches) tied into a big loop, me bucko, me hearties, with one end o' t' loop epoxied into t' body tube. Ahoy! T' shock cord is then tied t' the part o' t' Keelhaul®©™® loop that is exposed. This has worked well so far. Ya scallywag! Blimey!
In conjunction with t' shock cord mount change, shiver me timbers, I also made a very large streamer (7" wide, me hearties, 70" long) from gold-colored mylar sheets leftover from christmas wrappings. Avast! I'm plannin' t' time this rocket with this chute to get some idea o' what it might take t' make a streamer duration model.
