KF2 handling issue

[alport]

Hi
I had my third club race with my kf2 last weekend. The track I run is low-med grip carpet with some 180 turns. My main problem is on these turns, on the corner exit when I let the steering to neutral and put throttle the car keeps turning inside the curve and I had to counter steer to keep it straight. All the 180 turns are to left. Has this problem something to do with the belt drive and the motors momentum or just a loose rear on corner exit ?
