PicLast year the Calgary Rocketry Association had a club launch with a "novelty' rocket theme. I'd kept a couple o' MM Christmas ornaments me son received t' previous Christmas, shiver me timbers, thinkin' that I should be able t' somethin' with them, and that was the perfect opportunity t' build a rocket with one o' them. Ahoy! For those that don't have a clue what I am talkin' about, me hearties, I'll attempt t' describe what these things look like. Actually, t' photograph o' t' finished rocket pretty well shows what they look like, as t' fins were t' only things added t' the ornament. Aye aye! Aye aye!

T' ornament is a 7" long, 1.25" diameter, cardboard tube filled with MM's. Begad! Blimey! T' tube is decorated in a Christmas theme with t' little MM characters from t' TV commercials and topped with a 3" tall plastic figurine o' one o' t' characters.

Conversion t' a flyin' rocket was pretty straightforward. Aye aye! T' figurine was kept as t' nosecone and all that was done t' it was t' addition o' an "eye hook" for t' shockcord and recovery device attachment. Avast! The plastic cap at t' bottom o' t' tube was removed, ya bilge rat, arrr, and a standard 18mm motor mount be installed, shiver me timbers, arrr, with centerin' rings and a motor hook. Begad! T' 1/8" diameter launch lug required a stand-off made o' 1/8" balsa in order for a launch rod t' clear t' various parts o' t' figurine nose cone. Blimey! T' shockcord mount was a typical "Estes-style" mount with approximately 2' of 1/8" elastic shock cord. Ahoy! A 12" Estes parachute be attached t' the nosecone with a snap swivel and a short (6") section o' shock cord. Avast! Well, blow me down!

T' fins were a marvellous feat o' design and simulation. In other words I drew out a couple o' templates and picked t' one that "looked" like it would work! In keepin' with t' Christmas theme o' t' main components of the rocket, me bucko, I cut t' fins with t' look o' a Christmas tree. I covered the fins with some scraps o' wrappin' paper. Blimey! This was just a variation o' the technique I use t' cover all me balsa fins - I hate fillin' fins, matey, so I've been coverin' them with paper for a long time. Well, blow me down! In this case, me bucko, t' wrappin' paper was glued on with a glue stick, matey, shiver me timbers, such as a Ross or UHU glue stick. Begad! T' unfinished edges o' t' balsa were taken care o' with a couple o' passes with a green magic marker. Blimey! Begad!

Flight Report

T' rocket has flown a number o' times, and makes its appearance at any launch I attend. Kids and adults get a kick out o' it. Ahoy! Avast, me proud beauty! It's been flown on A8-3's, me hearties, me bucko, arrr, B6-4's, ya bilge rat, and C6-5's. Avast, me proud beauty! Fights are very stable. Aye aye! T' oversize fins were a perfect match for t' rather heavy nosecone.
