FlyingRC 45A ESC is a high-quality 4-in-1 controller with an excellent price/performance ratio, suitable for 4-6" drones powered by 3-6S LiPo batteries.
The controller can handle a continuous current of 45A per channel. The ESC is equipped with HYG011N04 MOSFETs with an on-state resistance of just 1.0 mΩ in a DFN 5x6 package. The PCB has 6 layers with 2 oz copper and two surface-soldered gold-plated copper strips that help conduct current and reduce resistance and heat generation. Control is handled by a 32-bit QF32F4AK8U7 processor at 120 MHz with an integrated ID6288 driver. The controller uses AM32 firmware, supports DShot150/300/600, OneShot and PWM, and handles sinusoidal startup with high torque at low RPM. It includes a current sensor and a telemetry TX pad. The included 680 uF/35V capacitor and power cable with XT60 connector must be soldered to the controller.
The controller has a mounting pattern of 30.5 x 30.5 mm with M4 mounting holes (M3 with softmount). It connects to the flight controller via an 8-pin SH1.0 cable.
