Loss of throttle.

[Thehotrodpig]

Hello, I have a bomber, I’m newish to rc. Having issues with the rig running fine for a few minutes and then complete loss of the throttle. Steering is fine just no throttle. Tried both freshly charged batteries and it doesn’t matter.

Here’s the specs

Rr10
Stock rx/tx
Mamba x
HH puller pro r

This last time it did it when I pushed the button to activate the crawl function on the Radio. Recently replaced the sensor wire as it had a broken wire. Checked all connections. Changed the batteries in the Radio already. Any ideas?

I have been tuning the mamba x a lot lately trying to get it just right. I guess I could have done something that it didn’t like. My tunes are pretty much what John Holmes recommends in his video.

Thank you in advance for any help. This place has been awesome to learn from.

Just went and pulled it back apart. Retuned the mamba x with some tweaks. Getting no error beeps or led flashes. Weird thing is when I spin the tire by hand while pulling the throttle it springs to life. I’m thinking my motor is crapping out. Any thoughts?

Could be a sensor issue. Broken pin as well as the wire?

The mamba x isn’t giving off the sensor error tone.

put a black mark on the pinion and motor plate when this happens, check to see if this happens when ever the pinion is on that mark. if it is there is a problem with the motor, send it in for a rebuild.
