I have the yellow Bob Hoover version and I love it. I also have the OS 70 but mine is inverted. The only problem I have had with the retracts is on one side. And on that side if I let It sit on the gear it bends forward slightly and I just bend it back before flight. The gear have handeled several dinked landings and heavy cross wind landings.

The closest thing to a bad habit it has is that it is more likly to get into an acelerated stall than any other plane I have flown. I almost stuffed it doing a very tight turn at about one mistake high. It snapped and spun.
