Hi Everyone,

I'm building a flying wing for FPV use, I run an epp one and although it's bomb-proof, my flying has got pretty solid now so I don't think that a slightly more fragile speed machine will be a problem (famous last words maybe!), I have cut the cores out of blue styrofoam and I plan to coat that with one layer of 160gsm glass cloth, does anyone have any tips on how to keep the cloth flat and to get a smooth finish as I really don't want to do too much sanding, getting a perfect finish isn't essential because i'll probably have to make a new one every few months after the inevitable!

Thanks Steve

I've done something similar with sport 40 wings.  I always did it the other way around.  I layed up the cloth with resin on release film then placed the foam core on top of that.  I rolled the film / glass layer around the leading edge and the vacuumed the whole lot.  I always got superb results like that.  I did find you need to do a slightly resin rich lay up to get a really good bond to the foam.
