Mato 1/16 Metal Chassis with Track tensioner Back Panel for Heng Long 3818-1 RC German Tiger 1 Tank Lower Hull Robot Chassis

it is an awesome reproduction of heng long tiger 1 3818. the problem is henglong gear box wont fit in the hull. you need to buy a separate gear box like Mato (only) MT 215 or MT 197. i am upgrading my plastic 3818 into this metal hull, and the old gear box did not fit.
