Help me understanding controlling Brushless motor

[alto777]

@codev200 see this old thread. It has a discussion about calibrating the ESCs.

ESC EMAX BLHELI Flash needed?

Hey, I got BLHeli 25A connected to brushless motor , it looks it got bad since randomly it will stop rotatating the motor ( I got 2 so I swapped and the issue went to the other motor) I bought a new BLHeli to replace the bad one, isnt it plug n play ? it doesnt work, connected the same way as the old one. both controlled via same pin on arduino nano .. so one motor works and the other one doesnt its not code related but maybe someone here had that issue [25a.jpg] [25a.jpg]
