RE: .60 size Beaver?
Unionville Hobbies in Canada makes Beaver Kits and I don't think they have a web site. I made one from the plans from one of their kits I found at a swap meet. It's a great flyer at 96" wing span with a 120 four stroke. Also KMP makes a glass fuse Beaver but it's a bit too pricey for me .....Seaplane
