RE: Avionnette HM-8 build thread.
For a purist and someone who is very good at flying radio control, yes, staying with the original would be best in my opinion. For someone like myself who needs all the help I can get when flying, I would probably put in about 1.5 inch of dihedral. All depends on what you are looking for in a model, authenticity or flyability. A note from a friend who is familiar with these airplanes. He mentioned that many people were killed trying to fly in the full sized ones, until the engineering fixed the problems. Heres another picture of another. Maybe one built in that era. Caley
