Hi , i am building the Widgeon now 80" wingspan , i am building it from RCM plans ,but have done it in my own way , the wing i am building as 3 piece in balsa sheeted foam. I have don some changes on the fuselage too.
I hope it will fly as good as the PAF Widgeon, (i saw a video of it).
You can see some pictures of my build here :
