I’m not sure on that particular plane, but sometimes you have to arm the esc. When you plug up the battery, move your throttle to full and wait a few seconds. After it beeps a few times, move throttle back to zero. That should arm the esc. Throttle should work after that. If it don’t, might need a new esc.
If you go to the monitor screen, does the throttle go up and down?
