Need help with throttling please!

Hello, I am trying to set up an rc plane and I have everything paired with the transmitter and everything seems to work except for the motor. I don’t hear a beep whenever I power it on but in the past I have used this esc before so I know it works. To see if it was an issue with the transmitter I would see if the pwm changes on mission planner for the throttle and it does change value. It has also been armed so that’s not an issue either. Please Help
