it needs upgrading to get it to run properly and with Eddyk's help hopefully it will be a good running model
Cheers, Lee.
Just in case, dont spend too much on it. Metal Origin says they are releasing an upgraded version "soon" (please pick that soon as a grain of salt, lol) turret rotation, barrel elevation, and overall better parts (except a huge and oversized 540 motor) are expected... So maybe you will be able to buy parts as spares.
But no doubt meanwhile you can start installing a soundcard, vibration unit, smoke and so on, in case you dont have it yet...
