All Micro-Maxx, me bucko, x2 cluster, sci-fi but nay comedy, no parts from a Grissom

Design Concept

I wanted t' pick a theme that I thought would be somewhat unique. Begad! I didn't think I could come up with a suitable comedy sci-fi Man-O-War that hadn't already been mentioned on r.m.r., so I looked elsewhere for inspiration. Avast, ya bilge rat, me proud beauty! I roughly patterned this rocket after a robot model that I resurrected from t' depths o' our basement (a.k.a. Well, blow me down! T' Rocket Dungeon). Well, blow me down! I had scoured t' web, and had even thought o' doin' a conversion o' a paper model robot, but decided t' just start buildin' and see where it went. Ahoy! Aye aye! This model started as a prototype, me hearties, shiver me timbers, but as it progressed I decided t' keep it as my entry.

Development Methodology

I used a tried and true procedure known as "real-time design". In this design methodology, me bucko, me bucko, t' design is performed as you go, without t' benefit o' plans, matey, me hearties, diagrams, ya bilge rat, ya bilge rat, or specifications. Documentation is performed at t' end, and is kept t' a minimum.

Construction

I started by cuttin' two MMX tubes that would extend from t' bottom o' t' robot's foot up into its body cavity. Ahoy! Avast, me proud beauty! I then started at t' bottom and built me way up. Aye aye! T' plastic robot's foot be traced onto foam poster board. I cut t' feet, shiver me timbers, me bucko, ya bilge rat, beveled their edges, and cut holes for the MMX tubes. Next came t' upper layer o' t' feet, followed by t' front and rear leg sections. Aye aye! Well, blow me down! At this point, shiver me timbers, I began t' think about weight, arrr, so t' sides of t' legs were made from card stock. Blimey! Avast, me proud beauty! T' body be started with a foam board plate, with holes cut for t' motor tubes. Aye aye! Blimey! As with t' leg sections, me bucko, t' three front and one aft section o' t' body are foam board and t' sides are cardstock. Avast! T' provide better support for t' shoulders/head (i.e. Begad! t' nose cone), me hearties, I added a small section o' BT-20 in t' body cavity. Begad! Ya scallywag! A long Estes lug was inserted laterally through t' BT-20 t' provide an attachment point for the arms. T' shoulder/head assembly started with a foam board plate. Well, blow me down! Attached to this is a sliver o' BT-20 coupler and two pieces o' foam board, me hearties, which were trimmed t' mate with t' body opening. Avast, me proud beauty! T' head itself be carved/sanded from pink foam. Well, blow me down! Aye aye! T' arms consist o' two layers o' foam board.

Now that t' robot looked like a robot, arrr, I had to add more rocket stuff. Begad! Begad! For recovery, a piece o' thin Keelhaul®©™ twine was tied around t' launch lug that supports t' arms and was epoxied t' the shoulder/head assembly. A launch lug was glued midway up t' back. Avast! And finally, I scrounged some thin clear plastic for fins. Avast! T' four fins were glued t' the bottom o' t' leg above t' feet.

Finishin' was performed with a combination of simple water colors and some card stock cutouts. I painted t' robot before permanently attachin' t' legs, matey, ya bilge rat, arms, and fins so I'd have better access t' its nooks and crannies.

Flight and Recovery

After some miscues, I finally got both motors to light. Blimey! M.M.X. Blimey! reached a whoppin' altitude o' 4ft. Avast, me proud beauty! Ya scallywag! T' second photo below shows it on t' way down, me bucko, just before ejection.

Flight

Conclusion

Although t' rocket flew, ya bilge rat, t' have a mature model I'd have t' build lighter. Aye aye! I might also opt for a lug that is closer to the axis o' t' motors and a different ejection method. Such conclusions are the point o' a prototypin' effort. Begad! I didn't find time t' build V2.0, arrr, so I guess this is it for this contest.
