I went to look at a TKS installation last weekend. The main wing leading edge wasn't as bad as I thought. It pushes the = leading edge about 3/8" forward and curves back to meet the existing = edge. So it's a slightly smaller radius. The horizontal stab, however, is quite changed. The TKS strip is at = least an inch in front of the original leading edge with a = correspondingly smaller radius. I would expect in both cases that the stall speed would be increased but = the more dramatic change to the horizontal stab is concerning. I'm wondering if if this kind of a change might mean difficulty flaring = and even worse stall recovery characteristics. ------=_NextPart_000_0BE2_01C4E26C.898AD920 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=3DContent-Type content=3D"text/html; = charset=3Diso-8859-1"> <META content=3D"MSHTML 6.00.2800.1479" name=3DGENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=3D#ffffff> <DIV><FONT face=3DArial size=3D2>I'm wondering if there are any airfoil = experts out=20 there.</FONT></DIV> <DIV><FONT face=3DArial size=3D2></FONT> </DIV> <DIV><FONT face=3DArial size=3D2>I went to look at a TKS installation = last=20 weekend.</FONT></DIV> <DIV><FONT face=3DArial size=3D2>The main wing leading edge wasn't as = bad as I=20 thought.
