I'm currently using a Vne of 125 mph flying my 4/1200 with 32 ft wing span. What's the groups thoughts on this? I'm currently cruising at 110-115 mph indicated.

My first question is this: How accurate is your ASI? Second is: What does Kitfox say the VNE supposed to be on the Kitfox 4? JImChuk
My pilot handbook, if I remember correctly, says 120 mph for the standard model 4 1200 and 140 mph for the Speedster. I assume the airfoil shape of the tail surfaces of the Speedster handle higher airspeed a little better than the standard model 4's flat surfaces. James Thomas
My understanding is it has more to do with the thickness of the windshield material.

Thanks for the replies. My ASI is correct. I don't plan on faster than 120mph but when I got my kit vne was listed at 125 in my limitations (skystar). Of course we keep speeds down in rough condions.

You're probably right DesertFox4 about the windshield thickness. I just figured the airfoil tail surfaces might be less likely to flutter at higher speeds. I do remember that the Speedster called for a thicker windshield. I suspect we're both right. James Thomas
