Hello guys,
a friend of mine send me this 1/10 buggy with hobbywing xerun xr10. It worked all well until... i don`t know what happened but suddenly i have only steering.
When i start the ESC there isn`t any sound or beeps for the cell count.
I`ve tried to recalibrate but nothing again. Tried to bring back stock settings and again nothing - only steering.
Can u help me?

sounds like you might need to get a volt meter and start checking out the esc

Try asking in here, there is a support group:

HOBBYWING TECH SUPPORT 1/8 & 1/10 OFF ROAD

Did you try a different (known charged) battery? Steering only often indicates a car sitting on the LVC setting.
