| Mamba x cutting out with impact
I'm hoping someone can give me some idea of what's going on here. The mamba-x in my TRX-4 seems to cut out when the car flips or bangs against something. The steering continues to work and power is still being sent to the rest of my truck (i.e. My lights stay on) but I lose throttle for about 5-10 seconds before I can drive again. I'm stumped. |

Maybe a loose connection on the ESC or motor? You could try wiggling all the wires related to the ESC and motor while you give it throttle or better yet set the cruise control.

I recleaned all the terminals/connections, so maybe that will help. | |

Brushed motor? I was thinking about worn brushes or if its rebuildable the wires for the brushes. I guess swapping to a spare ESC (if you have one) might narrow it down after more driving |

I was hoping there may be some fail-safe option that kicks in on impact and just needs to be turned off. LOL | |

Wyd, thanks for the info! Lots of stuff here I didn't even consider! I'll start a process of elimination after getting back from a hike tomorrow. I'll be able to see if it happens again and go from there.

Just a quick update to this problem. I inspected and cleaned up what I could on my rig as far as connectors and wires go. I was out for three hours with my rig yesterday and didn't have a single issue, so I'm going to assume it was a connection problem. What I did notice is that a power tap connector that splits off power off to my light system might have had a little too much dialectic grease on it as it was quite easy so slide/remove the connector. It's possible that impact was causing that part to move, although I can't confirm that 100% Regardless, everything seems to be working fine now. If this problem comes back, I will go over all the components and re-evaluate things. Thanks for all the suggestions! |

You still have the factory power switch on it? I have 4 Mamba X's, 2 of them have had problems with the switch .

| Re: Mamba x cutting out with impact I do, and I had trouble with the switch at the plug end last year. Fixed that with a good clean and dialectic grease. But I wouldn't be surprised if that switch comes back to haunt me later down the road.
