As I said in my first post on this thread, I have never cared for the design of the PT-40, even though I knew the designer. It is too stable to be a good trainer. The best thing would be to take out the radio and fly it as a free flight. Eventually the wildly excessive dihedral was reduced, but with the decalage and balance when built strictly to plans makes it a poor trainer when compared to an Sig LT-40. I think that suggesting a few changes to improve the handling is not out of line and well within the abilities of anyone with a loose association of the English language.
