• High quality speed controllers designed specifically for multi-rotor aircraft.
• Up to 600Hz refresh rates for an incredibly smooth yet crisp flight controller response.
• Power arming protection (prevents the motor from accidentally running when switched ON)
• Use new generation of the MOSFETs to make sure the ESC with low heating and more reliability
• These ESCs also feature excellent throttle linearity without sacrificing a rapid, crisp response to throttle input.
