Mine is not the airsoft version. I bought a Leopard and an Abrams with the IR "lazers"(Dr. Evil), so I can battle in the living room with my wife. She keeps claiming that the tank's pull to the left is causing her to get killed. What a crock! It is funny how she keeps getting killed with the Leopard, too. I am just lighting her up......literally

After reading the other posts, I am starting to think that something may have worked itself loose....maybe the idler wheel screw. Perhaps the 20% of normal driving that I experience is when the parts all have the correct orientation rather than a fluctuation in power distribution.

Sorry to jump in here on your thread, Rocketman1959, but thanks, everyone! [8D]
