Another area I have always wanted to address is the space between the horizontal stabilizer and the base of the vertical stabilizer. This is a notoriously high drag area on all airplanes especially on the Kitfox because of the open gap. I have thought a soft foam of some sort would work here because it needs to move freely with the trim. Maybe shaped to the rib and contact cemented to the rib to allow the foam to slide on the empennage panel freely as the stab is trimmed. Once I find the right material ,I'll give it a go and take pictures. Bruce N199CL
