Having finished the first fusalage Larry sent me new construction methods for the proposed ARF/ARC version.
This one is 3/8" sheet covered with 1/64" ply then the 3/32" nose doublers on top. It has lightening holes in the aft fus vs the built up aft section. The engine crutch and tank cut out are basically the same. It still has the rear weight hatch but tail wheel mount will be different.
