If you go over to the PT17 Stearman thread which is the same plane minus two ailerons you will find a conversion there. I forget the guys name but he did a real nice job. He also relaced the stock dummy engine with one made by Williams Bros., and made custom scale landing gear as the stock gear is far from scale.
Thank you Super08, I will search. It's sad there are not more biplanes available. I'd really like a large Pitts to convert. I'm stalking that new GP Pitts M12s.
