I sold a friend a used ACE 1015 for his SC10. I bought it used and never ran it. He's running a MMP esc and an Associated 2.4 radio. He has a DX3s on it's way. I was also running a 1015, MMP but with a DX3s w/o issues.
If the truck is on the stand and you tap the front wheels, it will shake the wheels back and forth rapidly... probably 1/8" left and right. If you grab the wheel or put it on the ground, it stops. Somebody at the track says it's not a problem. Ther the are no problems when on the track. Thanks.
