I bought the GSP Katana last year and sent in an email about the Sheer Web issue the plane was having when it was first released. I received a real nasty eamil from Irwin Siner telling me he worked his butt off travel 100,000 miles a year looking for good ARF's to sell and he didn't have time to deal with my question. Next year at this time GSP won't be in business if they don't put a cork in Irwin's mouth.
