<DIV>Jay,</DIV>

<DIV>Many moons ago, Don Lowe and Ron Van Putte were advocates of sealing the hinge gaps. In essence, the seal promotes improved control authority. Most importantly, it produces consistent response from the control AND flight surfaces by practically eliminating differential lift that may result from unsealed set-ups.</DIV>
<DIV> </DIV>
<DIV>Seal material may be almost anything that is flexible and light. My technique is pretty simple: I take a strip of clear iron-on film material designed for foamies and fold it in half lengthwise, glue side up. I run the fold over an edge to set and then insert it into the gap. With a thin straight edge holding the film in position against the hings, I use an iron set at the low settings required for foamie work and gently secure the strip of film aginst the flat surface of the wing/stab/fin post facing and the bevel of the control surface.</DIV>
<DIV> </DIV>
<DIV>I prefer the low temp adhesives of foamie clear film covering because there's less opportunity to damage the paints I use in my finishes</DIV>
