I made the modification to the PT-40 to make it into a Senior Kadet ARF. All you need is the dimensions of the plane and plug them into the right places. If you know how to edit an airplane with the edit feature you can do it. It is a little tricky, pay attention to the pop up help screens as you go. They will explain what each
parameter means. I also changed the visual scale to 2.0. Use the 4 stroke motor and it flies great, floats just like the real thing.
