I had the older spit also. I had a O.S. FP .40 in it. I covered it with Hobby Shack Cheap cote film covering and then spray painted the camo on. It flew really good.

Yes the glassing would toughen up the skin. If you go to the sure flight web site they talk about fininishing them with glass, latex paint.

I am going to be getting the 59 inch span Cub, P-40 and make them electric. The lighter they are the better they fly.
