Hi Bob, the Famo sure is an impressive model. That first road wheel just catches the occasional sprocket roller, if the suspension was set a little higher it would miss but as the suspension arm travels through it's arc it's going to just touch at some point. You can either let it all settle down with some run time or turn a few thou off the OD of the wheel (it's not the rubber tyre). Be interesting to see what others have done.
Hi Florian, the tracks do make that lovely halftrack "clatter" as the links contact the sprockets, again I think that will settle down with a little run time.
