Also keep in mind that whenever a component gets heavier you have to beef up whatever is holding it on.. metal wheels > metal suspension arms, metal tracks > metal sprockets and gearboxes. After you do that to a couple of tanks and the RC bug bites, you start ordering tanks & kits / parts with the final version in mind!

If you DO decide to spend a little more with a more robust model, (ie Taigen) I'd recommend going with any model with a metal lower hull.. off the top of my head that includes the Tiger, Panzer III, KV-1, the new Panther G/F, T-34, Sherman and even the Torro Tiger II.. a bit more coin but they're excellent for the cash!
