Leo, what in particular dont you like about the way ARF fuse's are made, is it the hollow built up construction? my only gripe is the heavy baseball bat wood, and the substandard "hardwood " sued for motor mounts. I build up my profiles the same way, a perimeter (I use 1/2" ) and then ribs inside, sheeted with 1/16, its in some ways stronger, and definetly lighter.
