I agree that the stock electronics are fine for most Airsoft Tanks, especially since they came out with the new V2 system, and I have a couple of Airsoft Tanks that are still on stock Electronics. What most guys complained about with the V1, myself included, was that they all had the same soundtrack and they didn't have proportional turret rotation. Personally, I've always thought that the motor controllers in the stock Taigen electronics are better than what's on the Clark board.
