RE: best US distributor?
I never use Asiatam 3:1 gearbox but I use Mato 3:1 gearbox that can change gear ratio in itself.
I have HL Tauch Panzer with Mato 3:1 gearbox and also upgrade all metal wheel with metal roller mount but Trank tensioner is hard to install.
Where can I buy conversion kit to other tank by use Panzer III lower hull?
