electric issue?
 

My friend was driving his tmaxx 3.3 today and it started handling funny New batterys didnt help. When going slow it turns just fine, but when speeds get faster it will suddenly vere left. nothing binding sitting still wheels turn fine, servos sound fine, throttle works fine. Iam guessing his having reciever problems? Any suggestions? thanks
