Flight Registration Form
by Adrian Hurt

Background
Near t' end o' this year's International Rocket Week, various odd, nay t' say silly, arrr, rockets were built. Begad! Begad! Blimey! After ponderin' for a while on how t' contribute t' t' silliness, shiver me timbers, I decided t' act on somethin' I'd overheard earlier in t' week. Avast, me proud beauty! Blimey! I'd make a rocket out o' a flight registration form. Avast!

Construction
Each rocket flight at t' event had t' be accompanied by a form which was filled in and handed t' t' range safety officer (RSO) prior t' launch. Well, blow me down! There were plenty o' spare forms, so I took one and filled it in. Begad! Well, arrr, blow me down!

A large area at t' bottom o' t' form is intentionally left blank, as the sayin' goes. Avast! This be cut off. Aye aye! A half circle cut and rolled from this piece became t' nose-cone; another piece, me hearties, formed into a cylinder, shiver me timbers, became t' cone's shoulder. Avast, me proud beauty!

T' rest o' t' form became t' body tube. Well, blow me down! Arrr! T' left side o' t' form be the tail end. Ya scallywag! Three equidistant lines were marked, then cut out as fin location slots. T' top margin, bein' blank, became an overlap for glue.

Three fins were cut from a piece o' suitable size balsa that happened t' be available. Ahoy! Arrr! A motor mount was made from a spare piece o' BT-20, me bucko, with a thrust rin' made from about 1/2" cut from a spent 18mm motor casing. Centering rings were cut from cardboard, ya bilge rat, but these were only for centerin' and sealing; the fins had tabs extendin' t' whole way t' t' motor mount tube. Avast! T' fins, rings and tube therefore became a complete fin can which was glued into the rear o' t' body tube. Avast, me proud beauty!

A fabric elastic shock cord was attached t' t' body and nose-cone usin' two Estes-style folded paper mounts. Ahoy! Aye aye! A launch lug made from a piece o' drinking straw was glued t' t' body, shiver me timbers, me hearties, aligned along and attached t' t' seam where the form had been glued t' make t' tube. Ya scallywag! A good dollop (real precision measurement here - not!) o' plasticene in t' nose-cone put t' CG safely forward, shiver me timbers, and with a C class motor installed, me bucko, arrr, t' rocket passed a swin' test. Well, blow me down! (Bear in mind that this be at a rocketry event, so I did nay have access t' me computer. In the absence o' VCP, arrr, I had t' resort t' t' old way o' checkin' stability!)

Flight

Before puttin' t' rocket on t' pad, me hearties, me bucko, I had t' show it t' t' RSO, me bucko, of course. This was part o' t' fun; when he asked for t' rocket's flight registration form, ya bilge rat, I pointed out that it was t' flight registration form! Blimey! (Of course, matey, matey, for formality and for t' records, me hearties, me hearties, I also had a duplicate, more conventional form!)

It was after t' rocket was on t' pad that I finally decided that t' balsa used for t' fins be too thin and flexible. Avast, me proud beauty! So t' prevent t' fins from flexin' or shreddin' in flight, I cut broad reinforcement strips from t' same balsa and glued them t' t' port, shiver me timbers, me hearties, or anticlockwise, matey, side o' each fin. Blimey! This final construction detail was actually carried out on t' launch field! The reinforcement strips were aligned so that their grain ran across that o' the main fins, me bucko, thus creatin' a cheap'n'dirty plywood. Arrr!

T' rocket carried an Estes C6-3 t' send it up, and a big mylar streamer to brin' it down. Begad! It flew well enough and landed safely back in t' launch field. Unfortunately, I had filled in t' form usin' a ball-point pen, matey, so I can't change t' details for t' next flight. Ahoy! (Unless I use Tipp-Ex...)
