Panther, do you have a stuart? Jack Yang makes the original style track for the Stuarts to get rid of the dumb dble pin track they put on them. He's on the Stuart website. Those tracks, the upgrades to proper gun, new mg with M-1917 cradle and a few sandbags really make it look like an M-5A1. Now if better electronics could be put it to make it run faster... I have a mini cam in the driver's compartment and it's almost like driving a real one behind the screen.
