My Kitfox II has a very low VNE red line on the airspeed indicator. I'm a Luscombe guy and many of the things I typically do with my Luscombe without thinking about it in the Kitfox raise the airspeed way past VNE before I even have a chance to notice it! I've had it showing 120 MPH several times and am starting to wonder what a realistic VNE is. Were there flutter problems in the past with these?
