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, matey, thinkin' that I should be able t' somethin' with them, arrr, me hearties, and that was the perfect opportunity t' build a rocket with one o' them. For those that don't have a clue what I am talkin' about, matey, shiver me timbers, matey, I'll attempt t' describe what these things look like. Well, blow me down! Well, blow me down! Actually, t' photograph o' t' finished rocket pretty well shows what they look like, me hearties, ya bilge rat, as t' fins were t' only things added t' the ornament.

T' ornament is a 7" long, shiver me timbers, 1.25" diameter, ya bilge rat, cardboard tube filled with MM's. Avast, me proud beauty! 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. Avast! Aye aye!

Conversion t' a flyin' rocket was pretty straightforward. T' figurine was kept as t' nosecone and all that was done t' it be t' addition o' an "eye hook" for t' shockcord and recovery device attachment. Ahoy! The plastic cap at t' bottom o' t' tube be removed, arrr, and a standard 18mm motor mount was installed, with centerin' rings and a motor hook. Ya scallywag! 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. Arrr! A 12" Estes parachute be attached t' the nosecone with a snap swivel and a short (6") section o' shock cord. Ahoy!

T' fins were a marvellous feat o' design and simulation. Avast! Aye aye! 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, I cut t' fins with t' look o' a Christmas tree. Well, blow me down! Well, shiver me timbers, blow me down! I covered the fins with some scraps o' wrappin' paper. Avast! Begad! This was just a variation o' the technique I use t' cover all me balsa fins - I hate fillin' fins, so I've been coverin' them with paper for a long time. In this case, t' wrappin' paper was glued on with a glue stick, me bucko, such as a Ross or UHU glue stick. Begad! Ahoy! T' unfinished edges o' t' balsa were taken care o' with a couple o' passes with a green magic marker.

Flight Report

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