the two sound only thing is in incorrect. on the 6.0 all 4 sounds could be cycled through on one board. with the 7.0 the sound quality was slightly improved and, as a result all 4 sounds could not fit, so the released a 7.0a and a 7.0b board. the 7.0a has the abrams and leopard and the 7.0b has the t-90 and tiger 1.
hey... what do you think happened to mine. I think I pressed something in which I don't remember anymore. I was just pressing combination buttons then when I'm toggling the forward lever, the other track is not moving forward instead it is turning left.. when I toggle the right.. it is moving forward. it was working before I randomly pressed buttons but now I don't know how to restore to the original controls..
for 360 you need a gear without a limit tooth. it's called 360 turret. then you need a slip ring of at least 12 cables. to rotate the tank, follow the instructions of the 7.0 system
