This model started out as a PDF plan downloaded through the OZ website. I converted it to DXF format to work with AutoCad and scaled it up to a 21 inch format, then decided the TD 051 was too much for such a light model, and more specifically, my advanced age and unknown ability to not get dizzy and fall on my face when I tried to fly it. So I upscaled it to 25 inch wingspan, and the only modifications due to the change in size was to go back and redraw the spar cutouts in the ribs to accommodate 1/4 inch square spars for the wing. I had just gotten a laser cutter, and was able to load the DXF file directly into the controller program for the laser (lightburn) and make the cuts for the individual parts including the ply doublers for the nose. The beauty in doing the laser cuts, is they are all generated from the original CAD files, and I knew they accurate because everything fit properly in AutoCad.
The build went uneventfully and the result is what is pictured. I will say that covering a lightweight 1/2 plane with monokote is really much more difficult than doing a larger C/L or RC plane. I now have all the parts cut for its big brother, a 42 inch Ringmaster for my Fox 35, and to follow it with the Daddy of the group, the Ringmaster Imperial, but those are for later times and posts.
