Highway,
The UCD 60 is one of the best planes I've ever had. Here's why, it flys like its on rails, easy to land, easy to TO and it does every trick in the book. I could teach on that airframe if I wanted to. As far as durability, I think its a great ARF, really put together well. If your talkin about crashin it in, that I couldn't tell you but its still built strong.
I would say if your going UCD, go 60 size. I have friends with the 46 and I say the 60 is better. It flys in the wind really well and its very predictable with a little time on it. Stall speed is so slow its hard to believe. I can lose an engine anywhere (within reason) and make the field no problem.
I've had a stick and that to is a great plane but I have to say givin the choice again I'd go UCD 60 every time.
Only other thing I might suggest is for a second you might want to go used. Less $ for the green thumbs, if you know what I mean. Good Luck!!
