Brief:
This is a scratch built model that I built for an Aerotech 24/40 reload case. Avast, me proud beauty! Begad!

Construction:
I got most o' t' components from an Estes Patriot model. Avast! I used two 7 inch long body tubes, matey, a 4:1 ogive nose cone, and balsa stock t' cut me fins. Begad! Well, shiver me timbers, blow me down! 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! Well, blow me down! 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 hearties, shiver me timbers, so I made an 8 inch section o' that and epoxied into t' tube, right above t' motor mount. Well, blow me down! That be t' permanent shock cord anchor strin' with a loop in t' end so I can change out shock cords quickly. T' coupler was friction fit into t' booster section for an 'anti-zipper' method. Begad! T' rest is pretty much straightforward.

PROs: cheap, me hearties, ya bilge rat, high performance flights

CONs: none

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

Flight Rating: 5 out o' 5

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

CONs: none

Overall Rating: 5 out o' 5
