Thanks for a quick reply! I will try your method. But still, the CS767 is at v1.5 already, and you have to disconnect the gen before they can be activated.. Those gen drive disc gaurds are not there for some reason, they are there so they can not be pressed accidently. I will try your method, and I will try re-installing the CS767. I do enjoy the CS767 because if its looks and its daily use operation simulations. Just so pitty that the CS767 isn't really ready, it looks pretty spot on, exept the winglets, but I can imagine how hard it is to proper model it.
