Boot loop when turn

[Extreme RCs]

Hello, I have a spectrum 6S firma yes he and I am currently using 3S on it whenever I turn the motor stops and the esc reboots please help

what motor?

When you turn the steering or when you hit the throttle the ESC reboots?

Check for bad connections everywhere between motor to esc and esc to Rx as well as rx to servo

Is is sensored? if so inspect the sensor cable, remove it and if problem goes away then replace with a new sensor cable

Are there any flashing lights/codes on the ESC indicating a problem?

If everything checks out then it could be a bad motor and may need to test with a known good motor... it may be possible that a bad motor damaged the ESC too so be sure to test a known good motor first before testing a new ESC.

I would unplug the steering servo and see if the throttle works normally. If it does I would try another servo. If that makes it all work then I would install the new servo in the car.

Sounds like the servo is "browning out" the BEC by overloading it, which is probably also powering the ESC's microcontroller, so the whole thing reboots.

Is the servo stopping within its physical endpoints or is it stalling out? That may be a factor if you've got a fast / torque-y servo that can pull several amps at a stall.

Nice call, I was just thinking a brownout as well if the steering is what's causing the problem... if the ESC is from Castle, they are notorious for brownouts even when the EPA is properly set and folks need to get a "Glitch Buster" capacitor so they won't brown out:
