Product overview
The EMAX Nano Series ESC 20A BLHeli Oneshot125 3-4S for Fpv racing 250 provides electronic speed control for racing multicopters and FPV multirotor builds. Its control functions use BLHeli firmware and support OneShot125, with active braking described as damped light on the 20A version. Quick throttle response is a stated feature. The electrical specification pairs a 20A ESC rating with peak current up to 40A and a 3-4S input requirement.
For integration into a multirotor control system, the ESC uses an opto design and a twisted-pair throttle signal wire intended to resist interference. Named compatible flight controllers include Skyline32, Naze32, Pixhawk and CC3D. The supplied selection is the default Nano ESC configuration, identified by SKU 0111004006. This is an ESC component for a build; its 40A figure represents peak current, while the specified ESC rating remains 20A.
