Is there any real life advantages to use I2C protocol instead of high refresh rate (300 Hz) PWM signal.
I think that if I use multicopter bigger than 50 - 70 cm in diameter with 10 -11 inch propellers (bigger propeller, bigger inertia) than the difference is very small. As I understand the use of normal (high update rate) ESC is more reliable than I2C ESC also.
then for 4 Kg quad copter with 80cm diameter it's preferable to use PWM or I2c Esc
