While waiting for suitable weather to prime the M.39, I started work on another Macchi, the M.33 flying boat, that I had been thinking about building. Using enlarged drawings from the Web and contemporary photos, I started by carving and sanding balsa into the wing shape. The shaped wings will be covered with styrene in much the same manner that I used on the M.39. The fuselage and outrigger floats will be plunge moulded and empennage shaped around balsa cores.

Thanks for your interest.
