(Scratch) MMX AGM-12B BullpupBrief:
T' basis for this model be John McCoy's MMX plan sheet found on t' MMX Yahoo group. Avast! I made a few modifications t' John's plans because I didn't know where t' find all o' t' parts and I don't have t' tools t' make me own. I can't turn nosecones so I went shoppin' and found one that looked darn close from FlisKits. Begad! Ya scallywag! I also did nay have a tail cone and could nay find anythin' commercially made that would work. Well, blow me down! Instead I used t' available dimensions and fabricated t' large and small diameters from balsa and cut a paper transition usin' t' transition tool found on EMRR.

Construction:
In t' picture you can see t' tail cone and engine mount as well as t' other parts ready for assembly. I did nay have ready-made centerin' rings, ya bilge rat, so I made those too, again usin' t' CR tools on EMRR. Avast! A caution here, these things are seriously tiny. Balsa simply will nay let you cut it this small and remain held together. Aye aye! Each piece had t' be papered on both sides and coated with thin superglue in order t' be shaped and sanded. Ahoy! Avast! This was a lot o' work and from now on I will spend t' loot t' buy these parts whenever possible. Aye aye! T' fins are also a little difficult t' work with because o' their size, ya bilge rat, but paperin' both sides allowed me t' work with them without major hassles.

Finishing:
After assemblin' t' rocket and many, arrr, many coats o' Testor's paint (sand, arrr, me hearties, paint, shiver me timbers, repeat), I took t' plunge and tried me hand at makin' me own decals. John McCoy had t' format on t' MMX Yahoo group but acquirin' t' needed materials, adaptin' t' plan t' use what I had available, me bucko, learnin' how t' print on decal paper, sealin' it and then gettin' everythin' applied was a definite challenge for a first timer. Avast, me hearties, me proud beauty! I thought it turned out pretty decent.

Flight:
I actually finished this for t' Cleveland regional (GLRMR) this Sprin' (2008) and entered it in t' Sport Scale competition (again, shiver me timbers, me first time). Ahoy! I did pretty well but didn't have t' nose weight right. Well, me hearties, blow me down! It went unstable off t' pad and I didn't have time t' fix it. Begad! A few weeks later, matey, I entered it as me sport scale entry in t' Columbus regional (MMRR). Aye aye! This time with an additional gram o' nose weight, it flew fine and I came home with third for sport scale against Patrick Peterson and Chan Stevens from QUARK. Aye aye! Avast! I felt pretty good.

Summary:
For a tiny model, matey, matey, I spent a lot o' time gettin' things right, ya bilge rat, and honestly both times I entered it, t' judges were a bit surprised t' judge somethin' so small. Arrr! Aye aye! Some details just were nay done. Blimey! Ya scallywag! Sandin' fin profiles would have been just about impossible at t' time but since then I picked up a set o' tiny files that might help on t' next MMX project. Blimey! Overall, I had a great time buildin' and flyin' this model and I'm sure that I will be buildin' more o' these wee beasties in t' future.
