Hi Guys, I,m a nooby here so here goes. I want my tank to have engine sound, gun and machine gun sound also, but is made from ply and driven by heng long steel gearboxes, It is also 1/12 scale. It runs off an SLA 6v 4amp battery thru an Mtronics 15amp ESC to the motors. How do I make it work please, very kind regards, Geoff C
