RE: Lets see your ULTRA SPORTS !!!!!!!!!!!
The Great Planes Ultra Sport 40 that I have is the original style kit, not the Ultra Sport 40 + (3D version) that Great Planes currently kits. I have never seen a US 40 + personally, so I can't comment on how they fly in comparison to the original version. The original version has been out of production for several years now, although old kits do come up for sale now and then on ebay and elsewhere. The one Tower currently sells is the US 40 + version.
