I don't believe it makes a lot of difference. Other issues effect performance more than this one. The issue is more one of practicality. Sharp trailing edges are more easily damaged. I have found that model airplane trailing edges work well as a base to reinforce this area to form the trailing edge.

This photo of Richard Shirley's trailing edge shows a blunt profile. http://www.bouyea.net/gathering2004/P1002293.jpg The Cirrus people told me this is done to improve the feel at higher rates of speed. (Interestingly, both Cirrus and Richard have aluminum ailerons.) Most of the KRs I have seen have very thin (i.e. sharp) trailing edge sections. Does anyone know definitively about what this type of change might do to the standard RAF airfoil?
