Buildin' t' rocket is pretty straightforward, it's really just a Fat Boy with big fins. Ya scallywag! Blimey! You can print out t' template for t' fins here.

If you don't have t' G10, balsa would work fine but basswood might be better. Begad! Well, ya bilge rat, blow me down! You might also use t' stock fins from t' Fat Boy kit as t' dorsal and ventral fins shown. Aye aye! These are just simple shapes and they just need t' look right as they don't affect t' aerodynamics o' t' rocket that much. Ahoy!

Replace t' centerin' rings and motor mount with t' set up shown below in the parts list. Blimey! Blimey! I be concerned about t' noseweight so I built it for 24mm just in case. Motor is friction fit and t' thrust rin' is a couple o' wraps of maskin' tape. 

T' BT is preslotted so just epoxy t' fins in place and install a fillet of your choice. Ahoy! Tack with CA till t' epoxy sets. Ahoy! T' forward fins are simply butt glued t' t' airframe with CA. T' airframe, ya bilge rat, fins and nosecone is painted with Rustoleum black lacquer but I forgot t' clean and sand t' G10 so it looks pretty horrible due t' t' residue on t' surface which caused t' lacquer to cat's eye and separate.

T' Tweety head needs a bit o' carvin' with an x-acto t' fit properly.  Trim and fit, ya bilge rat, repeat as necessary. Begad! Attach with hot melt glue.  The drinkin' spout needs t' be dealt with but a bit o' trimmin' with t' x-acto, arrr, me hearties, matey, a hot knife t' melt t' plastic took care o' it. T' fill in t' hole you can heat up t' spout in a clean flame till it's malleable then smear it into t' hole. If you have ever repaired your ski bottoms you know t' drill. Avast, me proud beauty!

T' graphics are made from 1 mil vinyl available at sign shops everywhere.  White for t' belly and teeth, ya bilge rat, red for t' tongue and a yellow t' match Tweety and represent his torso in t' sharks mouth. Well, blow me down! : ) They were mostly cut, fit, peel and install so be creative adn develop your own scheme.  I cut sections o' yellow vinyl t' represent t' mouth, overlaid it with t' tongue vinyl in red then overlaid that with t' triangular teeth.

T' deadlights are ellipses and lines done in a simple graphic program, arrr, arrr, printed on my color printer, matey, matey, cut out and glued in place with a glue stick.
