Both were used it has the 3 to 1 boxes and frame rate was altered for effect. Boxes are Asiatam, stock motors.

Thanks YHR I enjoy your videos as well.

I have a Bulldog . But it is hard to control with stock set up. I am running tanks and shooting at same time.. THe 3 to 1 gears make all the difference in the world on how the tanks run. Bulldog and KV-1 get them next. Would like Sherman with them installed. Maybe one day.
