This is an injection plastic and metal radio or remote-controlled military vehicle model.
There have been plenty of other mini-sized R/C items released in the last couple of years, but Konami's Combat Digi-Q tanks are by far the most fun! There's much more here than just driving around...
Full proportional digital response through infrared means that you can control turns and speed precisely through twin joysticks. Four transmission channels are available and your tank can be reprogrammed on the spot to any one of them, important because these tanks have a combat feature! Up to four participants can shoot-it-out as independent combatants, or as teams! Sensors on each tank register hits and they shudder in place when hit. Standard combat gives each tank identical capabilities. Switch over to Expert Mode for more realism; tanks' rate of fire, firepower and ability to take damage all vary by chassis!
Four AA batteries in the handset provide power -- the tanks themselves recharge their internal cells by snapping onto the back of the unit for 10 minutes. Then you're ready for a half-hour or more of action! Highly recommended.
