MT,
Looks good. I can say that when it comes time to sheet the belly, do not try it with a single sheet.

I got through it, but it was not easy. If so, it needs to be formed a bit beforehand with ammonia. I think it could be planked quite easily really.
I have the chin cowl done and to aid in construction of the frame I used some scrap 1/8" light balsa, cut into triangles, as gussets. I still have to dremel out the the inside of the front corners, but right now the chin weighs 1.8oz. I mounted it with nylon screws from the inside into the supplied blocks mounted in the chin frame, and very small screw at the front. I think this method will work quite well.
Wish I had more time to work on it...[:@]
Best Regards,
Mark
