I started to dismantle the Kyosho MR02 for the tuning parts that arrived. I got the atomic motor and the atomic ball differential. Have a look at the images:
Atomic Differential
Atomic Motor
The parts are compared to their originals which are always in the picture together with the tuning parts. Since the Kyosho comes with a standard and the so called eco motor there are 3 motors in the second image. The new atomic motor has already been put into the rear end of the chassis. Now only the ball differential is missing.
