Hi im new on here this is my first post. I purchased 4 new phantom opera 20 amp esc for my p1 and i cant figure out how to calibrate them. The motors wont start. Has anyone used these before? if so can you tell me a simple way to calibrate them just so i can start the motors, i can program them later but for now i would just like to be able to start the motors. Any help would be greatly appreciated.
