Notice: Only include ESC. Not include motor, flight controller, BEC showed in diagram picture. ESC Specifications: Input voltage: 2-6S Lipo Continuous current: 50A Peak current: 55A Current ratio: 300 Quantity: 1PC Size: 14x33mmProduct Net weight: 5g ESC firmware: HAKRC_G071-2023_Multi_32_9.Hex Protocol support: PWM, Oneshot125, Oneshot42, Multishot, Dshot150, Dshot300, Dshot600 Features: 1. PCB adopts high-end 8-layer 3oZ thickened copper skin and double pad design, which has stronger over-current capability and good heat dissipation. 2. MOS adopts imported 40V high current resistance MOS, which has long life and strong load capacity. 3. High density and compact, with built-in galvanometer and programmable LED lights, small size, high integration, simple installation and reasonable wiring. 4. Use industrial grade LDO, resistant to high temperatures. 5. Use high-quality Japanese Murata capacitors with strong filtering performance. 6. Supports image transmission of ESC telemetry data. High quality hardware: The STM32G071G8U6 main control chip runs at a frequency of up to 64MHz. Using three-in-one IC driver and high-frequency ceramic capacitor. High-precision PCB production process, the pads are all metalized to prevent the pads from falling off during use; 3 ounces of copper thickness, 8-layer board, greatly reduces heat generation, thereby improving efficiency. Hardware: PWM, Damped Light Hardware PWM drive, smooth throttle response, Damped Light technology, and regenerative braking function make the motor decelerate sensitively and effectively, with precise control; active freewheeling technology extends the endurance time; Package Included: 1x HAKRC 7133 50A ESC
