id recommend anything like the panzer lll or stug, same chassis just different upper, u can buy the panzer lll then buy the upper half of the stug later on if u wanna change things up cause it will screw right up to ur original stock holes, either way u go uve got a nice tank, personally my panzer lll i broke in the metal gearboxes and as of today she still runs great and ive had this tank a few years i think now havent had a single issue, matomart is all i deal through, packages always come in perfect condition to me.
