Esc constantly beeping when connectes to receiver

Hi, I have problem with my esc, I was testing motor and I accidentaly pulled down my throttle very fast and esc started beeping, I unplugged it and plugged it back, nothing, I tried removing receiver and it stopped beeping, as soon as I connect receiver it starts to beep. I can’t control motor and servo. I tried to calibrate it and nothing happened, maybe I don’t know how to calibrate it, can someone help me? Motor is bl3650-4300kv brushless, esc is 120a I don’t know name but its blue and there is v2.3 on it

Is this really for a Copter or did you post in the wrong thread?

looks like wrong thread :confused:

Right. Post in the Rover thread with a photo of the ESC.
