Mamba Reactor 66 is a high-end ECS designed for powerful 5" racing drones. The ESC uses high quality MOSFETs with low resistance. As a result, it supports current up to 66A per channel. The ESC can be powered by 4-6S Lipo batteries. The Reactor 66 ESC uses BlHeli_32 firmware, so it supports bidirectional dshot, telemetry and variable PWM frequency 24-128KHz. The ESC also includes a current sensor.
