The R8 receiver is the first receiver that can directly transmit the PIX and PX4 flight control data to your R/C controller. This can be used to display the flight control data directly on your radio. Apart from this is it just like any other 8 channel SBUS/PWM R/C receiver. Bottom line if you are looking for an R/C link to your Pixhawk drone, this is the receiver you should consider.
