Charge 'em...change 'em...drive 'em! You get two cool vehicles plus one interchangeable power module! Drive the off-road truck on land and drive the power boat on water. Click the power module onto the transmitter for a super-quick two minute charge, then snap it in and go! The power module snaps into all the other Power Changers TM vehicles, sold separately, for even more full-function radio-control action! The Power Changers TM Accessories include three more super-cool vehicles you can power with the module. Choose the robot, the tank or the racing buggy or get all three. Each sold separately.
