A cheaper and more plug and play way to have some fun during battling is to set up a tank with 2 operators. One controls the lower hull while the second operates the turret and firing. Just put 2 RX's in a tank, one bound to a TX for the hull and another bound to another TX for the turret. Of course you have to have the hobby grade radio's and amount
of people to do this. The most we've had were 16 operators for 8 tanks to do 4 vs 4. Absolutely hilarious to see some of the operators try and work together. Some were very successful while other you could actually see the steam coming out of their ears!
