Built up	Under construction

T' Sprint ABM was supposed t' be t' worlds fastest missile and got so hot the casin' had t' be ablative. Ahoy! Blimey! Well, blow me down! Blimey! T' acceleration be 100+g.

Construction

Ready...	...Launch

T' shock cord is plaited Keelhaul®©™® which looks like a shoe lace and has some elasticity. There is an inner Nomex® reverse cone that goes into t' very tail end. Blimey! I used CA for this and it went in easily. Avast, me proud beauty! Begad! T' nose cone is solid bass wood, turned needle sharp. Extra weight in t' form o' 4 washers is added behind t' screw eye, instead o' this I weighed t' washers etc. Aye aye! Well, blow me down! then drilled out t' nose, arrr, fillin' it with lead shot and epoxy which also anchored a Keelhaul®©™® cord loop t' connect t' t' main recovery system. Begad! I had seen newsgroup postings suggestin' t' model was unstable, me hearties, this mod added about 1oz t' t' nose, about 1" further forward. Blimey! T' finish t' model off as near scale you need to construct t' 4 tiny control fins which live half way along t' body. Begad! I can't get t' balsa bases t' look smooth enough and curved t' fit t' body, ya bilge rat, so I left them off for t' time bein' while I have a think about makin' fresh ones. Avast!

Flight

T' followin' excerpt is from "Sport Rocketry". T' intention is t' allow guests t' get a basic feelin' about a kit. We strongly suggest that you get a copy o' t' referenced Sport Rocketry and read t' entire article. Arrr! Inside you will find many helpful hints in construction as well as other useful information. For more information, me bucko, use t' two links above.

"T' Sprint ABM kit from Shadow Composites is a real nostalgia trip for anyone who remembers t' '60s."
"...hand-drawn isometric illustration in t' instruction sheet."
"T' Sprint kit is deceptively simple with only six major parts: a core tube, ya bilge rat, ya bilge rat, two centerin' rings, me bucko, nose cone and a two-piece conical shroud body."
"...extreme care is required when assemblin' t' centerin' rings t' the central tube...."
"T' body shroud consists o' two pieces, shiver me timbers, an inner cone made o' Keelhaul®©™® fire resistant paper, and an outer cone made o' heavy card stock with the surface details printed on it. T' inner cone is pre-cut for you, but t' outer cone must be cut out o' its large rectangular sheet."
"...the entire kit is made up o' paper and wood with one exception. The launch lugs are carbon fiber tubes!"
"There is almost no finishin' t' be done on this kit....only things you have t' take care o' are t' second stage fins and t' incredibly pointy basswood nose cone"
"Flyin' t' Sprint ABM requires careful attention t' t' CG."
"A stack o' steel washers is supplied t' place under t' screw eye in the nose t' further move t' CG."
"...the Sprint ABM is a fun kit....enough challenge in a few places to keep it interesting."

Overall, the article states this is a good kit that provides some challenges. Begad! T' article also provides an alternate method o' gluin' t' cones together that allows you to "dry fit" t' cones until you get them correct. In addition, matey, the authors suggests an additional means t' shift t' CG forward.
