I need some advise on restoring a 1/16 tamiya tiger I.

The tank is empty inside except the stock motors and gearboxes. The wheels is stock, and all the wheels are there. There is no motors or gears for the turret and barrel. There is some small parts missing all over the tank, but that should be easy to scratchbuild.

What I want is to get the tank back on it's tracks, driving around. So I need the speedcontrollers and the tracks. What kind of tracks and controllers can I buy, and where? What will fit and function well?

I have no manual for this tiger so I don't know how the mechanics should be like.
