Default Hot esc after battery connected

I bought a used helo, I turn on the transmitter, hook up the battery and it binds. at first the servos would move and the rotor would turn for maybe 15 seconds and stop, the servos will not respond but act like they are trying to level. Now when I do the startup process the rotor will not turn at all. The servos still move on their own without control inputs. The esc get super hot after about 2 seconds with no inputs. I ordered a new esc but is there a way to test the servos or anything else(voltage meter?). i also disconnected the motors and it reacts the same way.

Default Figured it out

Well after some playing around and disconnecting the servos one by one I figured out the elevator servo was out of adjustment, causing the servo to act sporadic. After some adjustments it's now acting normal. The esc seems to be pretty high quality even though it took a lot of heat.
