Feature: 1. 45A ESC: Highly integrated with four high performance 45A ESC, installation and wiring will become very simple because the integration is so high and the volume is only the same as the flat machine. 2. Anti Jamming and Fast Response: Not only support for normal PWM throttle mode, Oneshot125, Oneshot42 and Multshot ultra fast throttle signals, but also support for the latest dshot 150, 300 and 600 digital throttle anti jamming and high speed response. 3. Rich Feature: Use BLHeli S firmware, which is powerful and feature rich, supporting multiple ways to set ESC parameters or upgrade ESC firmware (such as by throttle signal cable, using other development boards, or using for cleanflight or for Betaflight firmware for ESC). 4. F4 V3S PLUS Flight Control: PCB adopts high end 8 layers 2oZ thickened copper skin, has strong over current ability and great heat dissipation. 5. Superior Craftsmanship: Uses industrial grade LDO, high temperature resistance. MOS adopts high flow resistance mos, long life and strong load capacity. Also with gyroscope, barometer and other functions, control and playability is higher.
