VsTank Pro Tank controllers feature a completely new MCU and battling system, which provides more continuous movement features than ever before in a 1/24 scale rc tank. The new features include two reverse speed buttons, two different speeds for turning left and right while still going forward and the ability to support up to 13 players using optional interchangeable crystal bands. Please note: All the tanks we sell are newer models which include this newer cotroller.

See this page (VsTank Tips) for installing your crystal in your controller.
