Brief:
This is a very simple "flyin' saucer" style rocket for Micro Maxx motors. Its main component is a 2 ½" paper bakin' cup.

Construction:
T' materials used include: one 2 ½"paper bakin' cup, one Styrofoam picnic plate, one piece o' note paper, maskin' tape, arrr, and a 2 ½" long Estes launch lug.

To make t' motor tube, I applied a thin layer o' white glue on some paper and wrapped it tightly around t' tube from an Aerotech Copperhead. Avast! Ya scallywag! After it dried for a while, I cut off a 7/8" section. Next, me hearties, I cut 1.875" and 2.375" rings from a Styrofoam plate. Ya scallywag! I made t' holes for t' motor tube a little big (oops), so I built-up t' motor tube with maskin' tape until it fit snugly. Well, blow me down! Arrr! T' smaller rin' be placed at t' end o' t' motor tube and set into the bakin' cup. Arrr! T' second rin' was slipped down until it just touched the sides o' t' cup. Arrr! Avast! This assembly was removed, and t' rings were glued in place with white glue.

After t' glue set, shiver me timbers, I made notches for t' launch lug and slid it through the rings. Avast! Blimey! It fit snugly and I decided nay t' glue it in. Avast! Blimey!

Finally, t' motor mount assembly was glued into t' bakin' cup. Blimey! Begad! While this dried, I set t' cup back into t' package on top o' other cups, in order to provide even support around its circumference. Avast, me proud beauty! Begad! I be originally goin' t' cut the lug flush with t' front ring, arrr, but decided t' leave it as is. Blimey! T' only finishin' step be t' application o' an American flag sticker.

Flight:
T' MMX motor is held in with a wrap o' maskin' tape. Avast, me bucko, me proud beauty! In order t' mate with the launcher, me hearties, me hearties, I had t' let t' motor overhang t' motor tube by ~1/4". Aye aye! The saucer flew straight t' an altitude o' maybe 25 feet and floated down nose first. Aye aye! Avast! Usin' a launch lug that is considerably wider than t' Micro Maxx launch rod didn't seem t' impact t' flight profile. Ya scallywag! After t' first flight, me hearties, shiver me timbers, thar was a little scorchin' o' t' paper near t' motor mount. Aye aye! This did nay get any worse after t' subsequent flights, so I assume it be because I did nay fully remove t' paper coverin' t' end o' t' motor mount. Ahoy!

Summary:
This simple rocket flies well and can be easily built while watchin' TV, cooking, matey, me bucko, matey, or performin' other non-rocket activities. Well, blow me down! Gee, am I obsessed or what? You can easily substitute different materials; I just used what I could easily grab.
