Working a little bit on the Kitfox 4 I'm rebuilding. Basically I have to sandblast the tailfeathers and controls, repaint them and then start reassembly. I peeled off the fabric on the trailfeathers a couple of days ago. There was an add on adjustable trim tab on the elevator. The hinges were pop riveted in place on both ends of the tab. Now get this... 3/16" aluminum rivets were used, and to top it off, when the guy drilled the holes, he went through both sides of the 3/8" tube. Took half the material away even though the rivets didn't go through the inner hole. Makes you wonder what goes through some people's minds at times. Anyway, got to get some welding done to patch it up. I got thinking, why not add a built in trim tab while I'm at it. Those of you who are flying Kitfox 4s, would you do it? If you don't have a trim tab, do your wish you did? Any body got any pics of theirs when they did? Thanks, JImChuk
