What is Oneshot 125 and why is it important for racing drones?
Oneshot 125 is a communication protocol that reduces signal latency to 125Hz, compared to standard 50Hz PWM. This means the ESC responds to throttle changes much faster, giving you tighter control during high-speed maneuvers — critical for FPV racing and freestyle flying.
