Basically, it works fine then all of a sudden it runs about 20% of the power. It might run for a little bit at 20% for a little bit or might stop straight away, then when you pull the trigger a few times later, it's full power again. It basically repeats this a few times when you use it.
The steering still works fine while all this is happening so it isn't the RX cable or radio. I've only just soldered new battery connectors/wires to the ESC (it was doing it before I replaced them). I'm pretty sure it does it with every battery I have so I doubt it's my batteries but I will verify tomorrow when I use it. I'll also try different versions of firmware.

I used to own a Hobbywing XERUN 120A 1/10 ESC that had the same issue and I never found out what caused it. Tried different batteries and firmware. A ton of troubleshooting and could not figure it out.

Can anyone help me? Please?!?!?!
