Lynn, I'm thinking you've got a really old kit in your hands. Everything new from Wedico today now has instructions in German and English, but I'll agree with you that these models are still a pain to build. Problem is Wedico uses 2mm screws and nuts for assembling almost all of the model's components. Almost everything is bolted together. There aren't many parts with tapped holes. Worse still is the fact that the pro chassis kits use cross members that don't have enough room to get your fingers inside of, so holding a nut, while trying to get the screw through the holes is a test of patience! These models are something you don't want to have to disassemble for maintenance, if you can help it. That's why I ditched all the stock cross members and started machining my own. I drilled and tapped every hole and now assembly is a breeze.
As far as the comments about us American's being the worst model builders, all I can say is Wedico isn't all that popular in it's own country, and I'm sure German modelers have the same complaints that we do. I heard from some Americans who have met Mr. Wedico in person that he doesn't much care for the way we modify the models he manufactures. Maybe if he designed them better from the start, he wouldn't have complaints about that!
