I just wonder what the pros and cons of using them are, in comparison to all ABS; or, a Taigen-like mix of metal turret, plastic upper hull, and so-called metal hull (for 'metal' read: plastic hull with inner aluminium liner)?
Weight would be the obvious factor, but I note that the Full-metal Mato (minus electrics) weighs in at around 6kilos. My Torro KT weighs around that much, but it's no slouch..even with stock electrics and motors, and so the weight factor might not be as significant as I'd supposed

torsion bar suspension. Which is better with weight I wonder? Maybe customising all-metal would be trickier that modding plastic.Certainly, it would have its challenges; but the prospect of all metal construction is very alluring: the 'grown-up' (real) one was all-metal, after all..and 'all meta'l also suggests greater structural integrity. Has anyone here build an all metal Mato?
