About every fifth landing, I'd come in a little hot and one wheel would flop in or out, and act like a brake. No big deal, but it's not a tight setup. There are six ball-links altogether, so a little slop is to be expected. I wish I could get a set of Robart folders in there, but I don't think they'd fit. The plane has about 40 flights on it now, and it still looks good. "War Weary", but good. -Tony
