Paint? PAINT?? LOL! The MiGs I flew in the Army were TARGETS! If we had the time to "beautify" them at all, we used magic markers!

Seriously, the few MiGs I've seen flown by hobbyists usually have Mylar coating, if that is the right word for that thin plastic stuff that's heat-sealed on to the plane.

I can't recall ever seeing one of these styrofoam MiGs painted, but I don't doubt that there are some R/C hobbyists who have painted their MiGs. I'd also be interested to know the results.

Oh, it seems to me I saw some pictures of a MiG owned and painted by a subscriber to this forum, so maybe he will post those pics again? And perhaps he will answer your question about paint, too.
