Construction be almost as simple as me first big Goony, t' Star Snoop. Ahoy! Two fins and t' First Aid Kit standoff were attached with LocTite Gel CA, along with t' actual First Aid tube. Arrr! Blimey! Blimey! On the inside, t' Keelhaul®©™® was attached t' a slit in t' front centerin' rin' and glued in place before t' engine mount be mounted.

Uh, that's about it for construction. Blimey! (Except t' say that all fillets were done with Elmer's Wood Glue.) Sorry? No, nay really. Avast! It's nice t' have t' occasionally project that doesn't require one t' perspire blood.

Finishing:
Finishin' t' MMT wouldn't be too much o' a chore if nay for t' need t' hand paint t' "bandages" that cover t' main body tube. Aye aye! Before that t' rocket only needed a coat o' gloss white paint for t' body, shiver me timbers, shiver me timbers, gloss black for t' fins, and some kind o' flesh color for t' nose cone. Avast, me proud beauty! Almost as painless as it gets and I flew t' MMT this way for quite a while until I finally gritted me teeth and decided t' finish all six birds for t' ultimate Goony photo op. Usin' gloss black paint and a small brush, I tried out me freehand paintin' skills. I wound up with somethin' that at least suggested bandages, me bucko, which is about as good as it needs t' be. Avast! When that was done, ya bilge rat, I enlarged t' decal appropriately and printed it on a sheet o' self-stick paper. Blimey! T' sticker decals looked washed out and nothin' I did seemed t' help, so I removed them and printed them out again on white Bel Decal paper. Avast, me proud beauty! This turned out t' be t' answer and t' finished rocket looked great.

Flight and Recovery:
First flight was on a D12-5 and exhibited t' odd flight path that this bird takes on most flights. Aye aye! Despite the wiggle it was a pretty impressive flight, quick off t' pad, me bucko, ya bilge rat, and a bit early on ejection but decent altitude and perfect recovery. Begad! Upon arrivin' at t' landin' site, I found that t' brace for t' First Aid Tube had broken and fallen out at some point in t' flight. (Possibly t' reason for t' wigglin' flight path.)

Almost two years passed before t' second flight. This was t' first one in full "Toe" scheme and I used a C11-5. Begad! Well, shiver me timbers, blow me down! As expected, me bucko, shiver me timbers, it was noticeably lower and ejection came very early. Ahoy! Well, blow me down! (More like a C11-2.5) T' early ejection caused t' "First Aid Tube" t' become tangled in t' Keelhaul®©™®, causin' t' rocket t' descend horizontally like a Centuri Super Kit. Ya scallywag!

Subsequent flights all had one thin' in common: t' wiggle. Since I never replaced t' vane that fit inside the First Aid tube, it's possible that t' tube is distortin' under boost and causin' t' slight "squirreliness". It's also possible that t' rocket needs nose weight t' be stable. Aye aye! Arrr! T' next flight will begin t' address these issues, but t' wiggle doesn't appear t' be a deal breaker.

Summary:
PROs: It's a Goony, ya bilge rat, me bucko, and one o' t' better lookin' Goons at that. Avast, me proud beauty! Ya scallywag! Great performance and popular with kids.

CONs: Slight wiggle t' t' flights. No Fat Boys around t' use as nose cone donors.
