Hey new to the hobby and I am having one problem with my new slayer pro 4x4. Twice now while using it the receiver lost power and all servos stopped working but throttle did not stay open. I'm wondering if it was weak batteries and this is a fail safe as both times I had about an hour on them. I have looked for a bad connection in the wiring harness and battery holder but found nothing. I put in fresh batteries and it powers right up. I shook it, kicked it, dropped it, pulled wires and it doesn't lose power. So I'm thinking fail safe. Anyone know for sure? Thanks in advance for any and all advice.
