I'm not anywhere close to this operation yet but since we're on the subject of foam I have a question. I bought 2 different KR-2 projects for constructing my airplane. One kit came with a huge (Aprox. 8'x3'x3') box of foam blocks, the foam kit that RR sells. As close as I can figure, this kit was purchased from RR in the early '70's. Is this foam still safe to use? It is still in the box and does not appear to have had much exposure to sunlight, etc. Also, I have a brand new RR VW motor mount still in the box that a fellow builder is interested in. I don't have a current price list from RR. Can someone tell me what they cost now? I want to make this guy as good a deal as I can but I have no idea what the mount is worth. Thanks, Ken
