Just got home will get an email off to you tonight. As for Kevlar, Its way over rated on layout boats, There are lots and lots of them that were made previously that are falling apart at the seams literally due to the very thin flimbsy finish of them. I wouldnt even consider a kevlar layout. Not only was kevlar not designed for layout boats but the cost over the weight difference in my opinion isnt worth the difference. And weight would be the only reason to use it. But with the light weight comes a weaker product due to all the flex it causes which then causes seams to split and crack. Kevlar is for adbrassion resistance. It will crack and break very easily.
