I've got a question for anyone who has flown the smith...

I was talking to my club's chief instructor the other day. He mentioned to me helping out another member of our club who had a miniplane. He said that the thing was very unstable and nearly impossible to control. A "real hand-full" was his exact words. This seems similar to elmshoots experiences. Is this typical? Has anyone else found this plane to be a hand-full?

Thanks,
Jeremy
