Main Control Chip: EMF8BB21F16G main control chip, operating frequency up to 48MHz, 3 in 1 IC driver, imported high frequency ceramic capacitor. High end PCB production process, pads are metalized cladding, so that you can avoid pads falling off when using. 3 ounces copper thick, six layers plate, greatly reduces heat, resulting in higher efficiency High Performance 45A ESC: Integrated with 4pcs high performance 45A ESC, double hole spacing design. With such a high degree of integration, the volume is only general size with the traversing machine, and the installation and wiring will become very simple. This incredible size and volume is specially designed for the racing class traverser Multiple Functions: Using BLHeli‑S firmware, powerful performance, support a variety of ways to set the ESC parameters, or upgrade the ESC firmware (such as through the throttle signal cable, using other development boards, or using cleanflight or Betaflight firmware to set or upgrade the ESC) Anti Interference and Quick Response: Support not only ordinary PWM throttle mode, Oneshot125, Oneshot42 and Multshot ultra high speed throttle signal, but also the latest dshot 150, 300, 600 digital throttle for anti interference and quick response. Input and output lines using soft silicone wire, very , and high temperature resistance, easy to weld What You Get: 1 x ESC,3 x Wiring,1 x Capacitance,1 x Plug ,8 x Rubber Mat,1 x Wiring Diagram, please feel to us if you have any question.We are committed to providing you with better products and services How to Use:
Speed controller programming instructions.
1. Enter the PROM, connect the throttle on the emitter using the simple option M, and move the throttle rod to the full throttle position without moving it.
2. Connect the battery, program initialization after the 3 seconds, the controller will start to beep, after completion, move the throttle lever to the lowest position.
