Traxxas EMaxx ESC / Battery Problems

[Dan Barlow]

Hi All, I’m having some trouble with my old EMaxx, I just replaced the LiPo batteries as the old ones had died. I’ve not used it for a while and with the new batteries fitted (possibly unrelated) it’s doing some crazy stuff with the throttle (steering is working fine). I assumed that the ESC needs calibrating but when I hold the button down to recalibrate it just switches the ESC off. Am I doing something wrong?

When switched on I’ve had no throttle at all, or it just randomly spins in forward and reverse when the throttle isn’t pressed. 
Thanks

If not maybe some crap under the button interfering with the switching it on / off long hold process. Can always crack it open and blow any crap off that's under the button.

What ESC? Brushed or brushless?

It the standard Traxxas EVX-2 ESC and titan brushed motors

Is your throttle trim neutral?
