I maidened the very light Scratcho with the PU wing today. Short report: http://www.rcgroups.com/forums/showt...1660287&page=4

One further comment on PU construction: I unfortunately had a disaster with paint sticking in my tail moulds today. That's another story, but in pulling the moulds apart it struck me just how easily the parts split and ripped open. The skins stayed stuck in their moulds and the PU ripped. I think likely that parts joined only with PU will tend to bust apart more on hard impacts, compared to the ones I've been making with blue foam cores and Ampreg edges. I think I'll be sticking with the latter technique for "good" builds, but the PU method is just so dang quick and easy I can see myself using it for things I'm not going to care as much about.
