LOL - Joe, I meant Dubro pinned hinges. I bet you thought I was four sheets to the wind when I wrote that one. A UCD with Robart retracts? I'm sill LOL. Do you have any pictures showing how you mounted your pinned hinges in such small surfaces. What size did you use? Did you cut any of the ribs off or drill right on through? What glue did you use? Epoxy or Gorilla?

Had another great day flying the UCD. The 91 four stroke is running just perfect. TR's and knife edges are just getting better. Had about 5-7 MPH North winds today and could land this thing in just about a full harrier. Not quite there, but only getting better.

Have any of you flown the 40 sized? One of the guys in the club asked to to find out how the 40 flies vs. the 60. I would think the 40 would be squirrelly as the dickens.
