A friend recently received the Lanier Yak 87" ARF.

It is a little bit bigger than what you said, but the quality of what I saw was outstanding.
It would a perfect airplane for a 50cc gasser, but if you want to be really wild you can put a ZDZ 80 on it (as he will be doing).

I was really amazed with how well everything fit together right out of the box, and there were no wrinkles in the covering that we could find.
