D12-5 Powered Christmas Tree Rocket - Flies great t' around 750' to 1000'

Construction is fairly simple. Ya scallywag! T' rocket is made up o' an 18" piece of BT-50 which is almost entirely surrounded by a large paper cone. Begad! T' cone transitions from .976" t' 4" wide over a span o' 15.5" and is made from poster board. Ahoy! Aye aye! There are 2 centerin' rings which hold t' cone t' the body tube. Blimey! T' bottom centerin' rin' also serves as t' base o' t' tree. Arrr! The rocket is designed so t' launch rod runs along t' body tube inside t' cone. T' followin' pictures show t' position o' t' 2 launch lugs:

Here are t' patterns and t' parts list. I split t' pattern for t' cone up over 4 pages with numbered alignment marks on each page. Arrr! Well, blow me down!
