I scratched a ultra sport 60 here a few years back, just before they released the kits again as you would know, anyway by the time I got the plans, canopy and wood I may have saved 35-40 bucks over a kit at that time. Not much of a savings considering I had to cut everything out myself.
Now its about 80 with the price raise. So it may be worth it for certain planes, the Extra is one I always figure on changeing out the ABS and landing gear before I even start it. So that extra cost is just part of the deal.

I almost always use Monokote also, UC is ok for some uses it may be a little easier to get around a bend, if it will stay there when your done is another question *L*
Like maybe a fully sheeted wing and fuse where one would want to iron the covering on the whole thing the UC may be a better choice for some.
I myself have not touched a large iron in over 20 yrs, just my trusty modified trim seal iron and a blow gun is all I use now days.
My main complant with UC is the heat and the way it wrinkles up on a hot day. When I get a plane finished with Mono if the weather is warm I set it out in the sun for a few hours and let it do its thing then reshrink it, after that I seldom have wrinkle problems. Can't say the same for ultracoat.

Back whern Goldberg owned oracover, it was made differently I have seen planes that was covered in it years ago and are still drum tight ,Technology I guess*L*
