RE: painting foam?
I checked at Wall Mart today for the Krylon Short cuts that vicman talked about and didn't find it, but did find a new paint they call H2O. It is a water based acrylic. No fumes (or very little) and water clean up. I came home and looked it up on the net and it says it is for styrofoam. That may be an option. A while back there was an article in one of the magazines that said to brush on a thinned out layer of light spackeling compound and then sand it down. That fills in the small holes and imperfections and gives a nice smooth finish after it has been painted. So that is what I did. It looks pretty good. Also covered a lot of the crash damage. Did I say crash damage? I meant to say very hard landing damage. The point I am trying to make is that if the Faskolor soaks in to the foam I am hoping that it will soak into the light spackeling that I put on. I would assume so seeing as how that light spackling is fairly porous. I am concerned about how tough the Krylon would be. Whatever happens I think the idea about the strapping tape on the bottom is good. I have used that to strengthen foam wings before. It is electric so won't have to worry about fuel eating anything. Other than the motor eating up a few amps.
When I am done flying my electrics all I have to do is wipe off a few ohms off the outside of the plane.
