Hi.
It would be very nice if you could include a small description of the hardware-side of this
The output of the SBUS receiver goes into one of the inputs on an inverter (74HC14). The output from that input goes into the serial port. The output of the serial port you are using goes into the inverter and the output will drive SBUS servos. You must have a common ground to all the devices. It is best to run the servos from a different power supply than the arduino.
