i made mine with the lost foam method of fiberglassing. i took the demintions of the firewall for the hight and then measured from the firewall to the thrust beering of the engine for the length then added a little to that so that i had somthing to attach with. i then just made up a number for the width and then imagination took over. i was rufly basing mine off of an exta look. i then carved my plug out of blue cor and covered it in packing tape then i just glassed it and sanded the finish till i was happy then i panted it.

the cowl in my pic is version 2 for my SSE the firs one was ok but i did not like the looks of it and when i upgraded the engine it gave me an excuse to make a new one.
