Except for the King tiger all the other tamiya german tanks have the wrong motor sounds. Watch youtube videos of Tiger 131 and the various panthers still running . There is a large difference in sound. Mostly due to exhaust profile. The tiger had larger mufflers where the panthers depending on type would sound different from each other because of the thinner early exhaust systems or the later flame retarding mufflers. Tiger 1s in good runing order are surprisingly quiet You hear the gearbox more than the exhaust.
