The covering is not as good in the hot sun as Monocote, mainly the black. Its not bad though, I would compare it to Ultracote to work with. In fact the colors match Ultracote best. It takes Ironing and heat gun well with out worry of burning. The only thing I did was replace the black on the wing and now all is fine. So far it seem like it will hold up well. I've seen ARF's with covering that is not near this quality.
