I am very interested in building a EU1-A, It looks like a good flying plane, for someone like me that just wants to play at pattern, and have nice looking plane this might be the one. I see several people are making fuselage but do not post the wing span and area, does anyone know what it is. The other thing I like about the EU!-A is the up right engine, make a great weekend flyer, but I would like to use a modern engine. Like a OS120AX with a rap around header. Think that would work? Back in the 80’s we had a Eu1 or EU1-A fuse, a friend made the stabs angle down and we cut a big set of wings put a ST2500 in it and he painted it like the F-4, he flew. Real fun plane. T Green
