The word metal gets thrown around a lot. When you are active in the hobby, you learn what is what, but for newbies, a Tank advertised as metal, and then arrives with a fair amount of plastic can be disappointing.
RE. I use blue locktite on the Mato metal wheel halves. Holds firm enough, but they pop apart when you need them to.
I know it has plastic for detail, but I'd call this a metal hull.
And Loctite wasn't enough to keep me from scouring the tank trail looking for roadwheel halves. I don't care what anyone says, those Mato roadwheels are a poor design and while I love my mato PIII and I intend to get the M36 when it comes out, I still say if I was getting just the PIII hull I'd take the Imex over the mato any day of the week. But again, it's not my money so in this case I fall into the old saying about opinions. They're like butts - everyone got one and most of 'em stink. I'm pretty sure Nick will do the research and really doesn't need my help, I'm just pointing out an option, as most of us like to have all the options before spending the hard earned coin.
