The latest use was on the vertical and horizontal stabs on the surfaces opposite where the counterweights are. I first make the surfaces perfectly flat and true as possible within the constraints of not sanding into spars or down into the threads of the carbon. Then I micro on a layer of foam. The foam is very easy to sand, and if one is very careful, a nice surface with just the desired gap can be created. Then a couple of layers of very light weight fiberglass cloth are applied (2 bid of 2 or 3 oz. cloth). The advantage of this approach is your are using very light weight materials while getting the desired finish and gap. Another thing a builder can use the foam for is to micro strips to the leading edge of the rudder closeout or the elevators. After careful sanding to achieve the desired shape and gap, on goes the fiberglass cloth. You could also use carbon cloth or heavier fiberglass cloth in areas where you might desire a little more strength (such as the lower part of the rudder leading edge which might be at more risk from rocks thrown off of the propeller). That foam is good stuff. Makes it easier to get the desired shapes. I'll be using more of it than is supplied in the kit. Hope that helps. Regards, Ron Jones Legacy Kit #181 ron@baronboys.com
