Features: brand new and high quality Mixing mode (default) (throttle/steering mode): 2 or 3 channels (2 channels are recommended, which automatically return to the center) to control the throttle, 1 channel (or 4 channels) to control the speed difference steering, the throttle ratio is , the steering ratio is , and the steering priority is given. Suitable for: Tanks, 4-wheel drive car. Dual independent: Equivalent to two independent ESC. Two-way synchronization: In the mixed control mode, if the single yellow wire is not connected, or the single yellow wire is connected to the receiver "-", the two motors will be controlled by the accelerator synchronously. Parameter: Support voltage/current: 6v-14v single 5A, single peaked 7A (for 2/3S lithium battery). The bec outputs 5v and the max. is 1.5A to meet your needs for power supply to the receiver and flight control (Note: the onboard microcontroller is also powered by 5V <connected with bec>, if you plug the 2S lithium battery <7.4V> directly into the receiver, the microcontroller will burn in seconds. <Max. withstand voltage 6.5V>). With runaway protections, power failure protections, overcurrent protections (but repeated overcurrent in use may also burn), overheat protections (130 degrees). Each group of motor wires is directly connected to the motor, do not mix it up, otherwise it will damage the ESC.
