When I got back into RC again about three years ago I sat down and made a list of all the RC planes I had built that I could remember. It was something like 45 planes. I would have to have a second house or a large workshop to house them all. Some were just great, others OK and a couple I didn't like at all. Like the Great Planes "Fun One". That plane just felt like it wanted to fall out of the sky unless watched closely. It wasn't pleasant to fly at all. Also a Sig Clipped Wing Cub that was a handful. I just rebuilt that one but didn't like the way it flew.
The Fun One that wasn't fun at all.
