I wasn't really aware of problems with the Toko Strutters when I built them, but it was a long time ago. The main thing I remember was the need to brace the fuselage halves apart at the top so the top decking would line up, and that the W struts didn't really want to align, a common enough problem with many kits. You don't get the amount of detail that's in the Flashback kit, but then again they cost a lot less too. Decals, though, were always a problem with Toko, and I don't suppose they've improved with age.
