Hi Carl,
Thanks for the info. Did you do a split type of flap like the "real" plane, or are these full flaps? Not sure I'm familar with the Robart hinges. Are you talking about the "Robart Hinge Points"? Why set them at 90 degrees when closed? I've attached a pic I found and modified which I think is sort of what you are describing. Let me know if I'm in the ballpark with this one.
I think I will fly it without them first, but I am considering putting a Zenoah G26 on the nose and I believe that will make it on the heavy side and expect landings to be rather fast. The flaps are probably going to be a necessity.
Thanks again,
