Having recently purchased a 1/16th scale RC Centurion tank from HAYA . I found the personal after sales service excellent, nothing was too much trouble, something rarely found. these days. The tank comes as standard with metal upgrade and is well made including things like rubber tyres, real wire tow ropes, recoiling main barrel and revolving commander's compartment. For all the other high quality components you will need to see HAYA's specification. I found the build strong, the 1st class controls well fitted and the advanced transmitter had potential for possible addons. This fully functional high quality tank is an outstanding replica of the iconic Centurion, I think it is a superb looking model which has taken pride of place in my collection.. Mike.
