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

Uh, me bucko, me hearties, that's about it for construction. (Except t' say that all fillets were done with Elmer's Wood Glue.) Sorry? No, matey, matey, nay really. Well, blow me down! 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. Blimey! Ya scallywag! Before that t' rocket only needed a coat o' gloss white paint for t' body, gloss black for t' fins, and some kind o' flesh color for t' nose cone. 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. Avast, me proud beauty! Begad! I wound up with somethin' that at least suggested bandages, ya bilge rat, which is about as good as it needs t' be. Blimey! When that was done, ya bilge rat, I enlarged t' decal appropriately and printed it on a sheet o' self-stick paper. Begad! Ya scallywag! 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. Begad! 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. Begad! Arrr! Despite the wiggle it was a pretty impressive flight, quick off t' pad, and a bit early on ejection but decent altitude and perfect recovery. Ya scallywag! Upon arrivin' at t' landin' site, me bucko, ya bilge rat, I found that t' brace for t' First Aid Tube had broken and fallen out at some point in t' flight. Avast, me proud beauty! (Possibly t' reason for t' wigglin' flight path.)

Almost two years passed before t' second flight. Avast, me proud beauty! Blimey! This be t' first one in full "Toe" scheme and I used a C11-5. Arrr! Blimey! As expected, me hearties, it be noticeably lower and ejection came very early. (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. Avast!

Subsequent flights all had one thin' in common: t' wiggle. Arrr! Begad! Since I never replaced t' vane that fit inside the First Aid tube, ya bilge rat, arrr, 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. 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, and one o' t' better lookin' Goons at that. Begad! Great performance and popular with kids.

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