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

Construction:
T' materials used include: one 2 ½"paper bakin' cup, arrr, me hearties, one Styrofoam picnic plate, one piece o' note paper, maskin' tape, shiver me timbers, 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. Begad! Begad! After it dried for a while, I cut off a 7/8" section. Well, blow me down! Ya scallywag! Next, I cut 1.875" and 2.375" rings from a Styrofoam plate. Begad! 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. Ahoy! T' smaller rin' was placed at t' end o' t' motor tube and set into the bakin' cup. Well, ya bilge rat, blow me down! T' second rin' be slipped down until it just touched the sides o' t' cup. Begad! Well, blow me down! This assembly was removed, matey, and t' rings were glued in place with white glue. Avast! Avast!

After t' glue set, I made notches for t' launch lug and slid it through the rings. Begad! It fit snugly and I decided nay t' glue it in. Well, blow me down!

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

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

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