Great job on that "PT-19" ! It looks like it might have more than just a bit of Kadet DNA in it. I did a Kadet based yellow Cub ( a"Kubdet") last summer and had fun fooling folks at the flying field with it. I bet your PT-19 fools people too. And yes, on the Kubdet I also moved the entire vertical stab assy forward as you suggested to convert to a taildragger. That change makes life (and the conversion) easier.
