Brief:
This is a scratch built model that I built for an Aerotech 24/40 reload case. Blimey! Blimey!

Construction:
I got most o' t' components from an Estes Patriot model. I used two 7 inch long body tubes, ya bilge rat, a 4:1 ogive nose cone, me bucko, and balsa stock t' cut me fins. Arrr! I made my own plywood centerin' rings for a 24mm motor mount. Begad! Blimey! I started by cuttin' my own fins out o' 1/8 inch balsa stock and epoxyin' them t' t' body tube. Avast! Avast! I then made t' motor mount out o' t' plywood centerin' rings and epoxied the assembly t' t' inside o' t' body tube assembly. Avast! There be some flame-retardant pink strin' layin' around, arrr, so I made an 8 inch section o' that and epoxied into t' tube, me hearties, right above t' motor mount. Begad! That be t' permanent shock cord anchor strin' with a loop in t' end so I can change out shock cords quickly. Avast, me proud beauty! T' coupler be friction fit into t' booster section for an 'anti-zipper' method. Avast, me proud beauty! T' rest is pretty much straightforward.

PROs: cheap, high performance flights

CONs: none

Finishing:
I used several coats o' white primer and then shot with Krylon florescent orange. Nothin' special in t' finishing.

Construction Rating: 5 out o' 5

Flight:
I made this rocket for use o' me Aerotech 24/40 case. Begad! Well, blow me down! I haven't got around to flyin' it with that casin' yet, but I have flown it several times on Estes black powder motors. Ya scallywag! Blimey! For flight one, me hearties, I use an 18/24 adapter and flew it on a C6-7. Aye aye! Arrr! Everythin' worked perfectly. Arrr! Begad! For flight two, I used a C11-7. Blimey! Avast! Again, everythin' worked wonderfully until it landed. It ended up in a daycare playground. Blimey! T' area had a high fence on it and it be right off o' a major road. I decided t' climb t' fence t' get me rocket back. Well, blow me down! Arrr! Flight three was at a MC2 monthly launch on a D12-7. Avast, me proud beauty! Wonderful flight t' start off t' day.

Recovery:
I used 13 feet o' nylon shock cord that I found at a military surplus store. For t' parachute, matey, I used a homemade 12 inch parachute made out o' a garbage bag. Arrr! T' anti-zipper method worked great.

Flight Rating: 5 out o' 5

Summary:
PROs: Easy t' build, ya bilge rat, high flights

CONs: none
