Since Tamiya is behind this R/C M4 Sherman, authenticity in scale, body detailing, and working suspension goes without saying. Acoustic authenticity is also high on the score sheet, through the digitally recorded sounds of a real Continental R975-C4 9-cylinder engine, which roars from the bowls of the tank as it runs. Speaking of the running, you will be able to recreate all the speed and nimbleness of the full-sized M4 Sherman with state of the art R/C technology.
