This is really a pretty basic rocket. Arrr! Blimey! I really got it t' try somethin' other than an Estes kit, and figured that it would be best t' start with somethin' simple. Blimey! One o' t' cool things about this rocket (and every other rocket I have from Custom) be t' mylar parachute. Avast, me hearties, me proud beauty! Blimey! T' rest o' t' rocket (motor mount, me hearties, shock cord mount, ya bilge rat, fins, etc) is all just like Estes stuff. Ahoy! Blimey! 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, arrr, and a few easy decals for a nice looking rocket. Well, blow me down!
Probably t' best thin' about this rocket, though, arrr, is its performance. Avast! Well, me bucko, blow me down! It's fairly light for its size, and (at least compared t' most o' me other rockets) screams off t' pad. Ya scallywag! Aye aye! In fact, ya bilge rat, shiver me timbers, on its very first launch, t' motor be announced to t' bystanders, me bucko, and got quite a reaction for its lift-off speed. Avast, me proud beauty! It goes pleasingly high on a B6-4, ya bilge rat, and goes out o' sight on a C6-7. Arrr! Begad!
After t' first day o' launching, shiver me timbers, arrr, I noticed that t' shock cord was 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. Ya scallywag! 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, arrr, t' part just above t' shock cord mount, isn't fully protected, and gets burnt. Ahoy! As a test remedy, matey, me bucko, I tore out t' shock cord and put in another mount, only this time I used Duco Cement t' glue in a bent piece o' paper clip, matey, t' which I attached a steel fishin' leader. Begad! I then tied t' remainin' elastic shock cord (with nose cone and chute) t' t' other end o' t' steel leader. No burn-through problems any more. Avast!
Unfortunately, durin' t' 1997 Oct 4 launch, me hearties, I lost t' excellent mylar chute because I forgot t' close t' snap swivel shut before launchin' it. Avast, matey, me proud beauty! Even without t' chute, it recovered fine with simple nose-blow recovery. Well, blow me down! This has led me t' believe that this model is a good choice t' test alternative recovery devices. Ahoy! I have built a small, arrr, 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. As o' 1997 Nov 8, me bucko, shiver me timbers, I haven't had a chance t' test it yet, due to t' incredibly lousy weather around here (3 straight weekends o' nothin' but rain! :( )
Update... Well, blow me down! Ya scallywag! Well, that x-form parachute failed, but t' rocket recovered just fine on with nose-blow recovery again. Ahoy! I have, ya bilge rat, for t' moment given up on x-form parachutes. Ahoy! Well, blow me down!
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, ya bilge rat, so I ripped them out. Arrr! Blimey! 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 hearties, with one end o' t' loop epoxied into t' body tube. Begad! Blimey! T' shock cord is then tied t' the part o' t' Keelhaul®©™® loop that is exposed. This has worked well so far. Arrr! Well, shiver me timbers, blow me down!
In conjunction with t' shock cord mount change, I also made a very large streamer (7" wide, ya bilge rat, shiver me timbers, 70" long) from gold-colored mylar sheets leftover from christmas wrappings. Well, me bucko, blow me down! 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.
