Having issue with motor running itself when ESC powered on.
 

I got an ARTR XRAY XB2D on the for sale forum of this forum. It has Tekin Gen3 Redline Spec-R 17.5T motors, and Hobbywings ESC powered with 2S battery. When I pair the receiver and power it on, the motor is running itself. I tried 2 receivers. I got an MT12 4in1 radio with a Radiolmaster receiver. Also got a DumboRC X6FG. After I bind it, the motor of the buggy starts spinning itself. I thought maybe I was doing something wrong with the DumboRC receiver, so I tried the Radiomaster receiver and something happened. I also have a Kyosho Syncrono KT-200 with a receiver and the same thing happened. These Radios and receivers work on other trucks/buggies. Is this a faulty ESC or does anyone know how to fix this?

I got the videos, but due to my account being new, it doesn't let me upload to the post.

Look up the manual of that ESC and follow the calibration procedure.
