I just finished one that people said didn't fly either. I had read comments like "I've never seen one make a second flight," but I gave it a shot anyways. I've probably got about 30 flights on it now. It's a handful, but far from unflyable. Give it a shot, and take it easy; it might not be so bad.

I know that one, because I was looking for one a while ago. I didn't find until I had given up and bought something else.
