Hello, I am new building drones, and I recently built my first quadcopter but there is a problem: when I calibrate my ESC, I can hear that the rotors are at full speed, so I disconnect my battery, I connect it again and when I arm the ESCs, they are spinning at about 50% their maximum speed. Which means that the quad cannot take off.
I have tried re-calibrating the ESCs several times but it just does not work.
I was thinking of erasing all data on my flight controller and start from the beginning but I don't really know how to do that :/
Thanks.
