If you're looking for a more scale appearance, American Models has a more scale sized dummy coupler that takes the place of their large Flyer compatible ones. Mounting them on a Flyer truck may be a bit harder, though. In any case, talgo mounting is the only way to go on tight curves. I have a train with talgo mounted dummy couplers and it negotiates tight curves just fine. I don't concern myself with operating couplers on this train since it's a passenger train, and runs as a unit.
