Hey David,
Sure, here it is:

A couple of things in here too:

Reading articles on the design (check various attachments in the several threads) you'll find out that Ken Bonnema (the designer) conceived the Brushfire as an intersection between the very popular P6/P7 (have to cross check the design date against the Phoenix design evolution timeline) and the EU-1A. This alone was the main thing that sprung my interest in re-designing it for a modern frame up. Initially, as you'll read, for a RE inverted Webra Speedy 12 on David Wood's suggestion, and then, when I started thinking about an interesting candidate for a plugin wing design with an upright RE setup using one of the power brutes including a 5 port OPS gold head that I have (maybe the most well engineered engine I have ever seen - even today. The balance is incredible). The A-shape internal structure of the fuse design is a perfect idea for a 10 degree (9.5 to be precise) straight shot rear exhaust configuration. The canopy would be made of FG. The bottom front half would be made into a recessed hatch for access to the goods.
I've gotten the bulk of the planform design done but just got started on the formers which is time consuming. I've gotten better at
synthesizing those out of a basic planform rectangle though. They tend change internally as I go through the process of the internal gear installation. In any case, as I have it, I suspect it could easily come in at 8.5 lbs or less. It is slightly oversize compared to the original - not much.
