Hmm..........so you are going for the M26 with metal tracks and some upgrade options........is this wise for a complete newbie?..........you may not like this hobby and if the tank gives you some grief( highly likely) then the frustration kicks in. Also, you have spent quite a bit of dosh on a model by then...................... my advice would be to pick a standard M26 S & S and go with that. Have fun with it then decide on your upgrades - if any (not compulsory of course).
cheers
