Pulled my truck out for the first time this year and it wouldn't really go, just a lot of jittering. Tried two batteries same result. The lipo actually triggered the low voltage detection after a few seconds and the red lightblinked until I unplugged.
I had an engine rebuild kit and was due anyway so rebuilt that. But after piecing things back together it's the same result. If I pick up the back tires then they do spin but if I set the truck down then the resistance causes it to just jitter again.
What should I look to replace?
