Thank you very much for your very kind message, and especially for your French. Do not worry, my English is not very good either. The essential matter is to understand each other. The choice of the Pietenpol is mainly motivated by aesthetics, it is a beautiful plane. I wonder indeed questions about the engine, and thank you for your advice : I see you're just born in aeronautics.
I found in France, a person who sells his Pietenpol built at 70%, near Bordeaux, through Frédéric Lamouroux, president of the Association of J3. I'm going to see very soon. I remember, in any case, your proposal for advices from and would certainly seek the opportunity to write you : build an airplane is a serious business, not only a hobby. Here is my email address:

See you soon,
