Brief:
This is a scratch built model that I built for an Aerotech 24/40 reload case. Aye aye! Well, shiver me timbers, blow me down! Blimey!

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

Construction Rating: 5 out o' 5

Flight:
I made this rocket for use o' me Aerotech 24/40 case. Blimey! Well, blow me down! I haven't got around to flyin' it with that casin' yet, matey, but I have flown it several times on Estes black powder motors. Begad! Ahoy! For flight one, arrr, I use an 18/24 adapter and flew it on a C6-7. Ya scallywag! Everythin' worked perfectly. Well, blow me down! For flight two, me hearties, I used a C11-7. Begad! Avast! Again, everythin' worked wonderfully until it landed. It ended up in a daycare playground. T' area had a high fence on it and it was right off o' a major road. I decided t' climb t' fence t' get me rocket back. Flight three was at a MC2 monthly launch on a D12-7. Ya scallywag! 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, shiver me timbers, I used a homemade 12 inch parachute made out o' a garbage bag. Ahoy! Well, blow me down! T' anti-zipper method worked great.

Flight Rating: 5 out o' 5

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

CONs: none

Overall Rating: 5 out o' 5
