RE: "World Models"
World Models makes some good airplanes. Yes, the instructions aren't great but they are usually accurate at least which is more than can be said of many no-name ARF's. One nice thing is that they often label hardware bags with the corresponding assembly step. Speaking of hardware, WM almost always has good stuff unlike the no-name guys.
I really don't care for the WM covering but it isn't the worst I've seen either. They sell it by the roll if you ever need to make repairs. Be sure to beef up the firewall with a little tri-stock and epoxy if it looks at all questionable.
The best part about this manufacturer is the way their planes fly. I've never met a WM plane that wasn't a great flyer.
