Hi,
Those of you who've built this bird: Did you have this much slop in your control-surface hinges? I'm building one for a guy, and on this one, the elevators can move up and down about 1/16" at the hinge-line, which amplifies out to almost 1/4" of slop at the elevator TE. The ailerons are nearly as sloppy--as though the wire that serves as the hinge-pin is too small for the hole in the G-10 hinges.
Thoughts?
