The short answer is "Yes". the longer answer is "Yes, but".....
You can setup the Dual Rates and Expo on EITHER the transmitter, OR the FT aura. NEVER DO ON BOTH! Preferred is always use the FT Aura to set dual rates and expo. Launch Assist may not work if the transmitter is either programmed for Dual Rates and Expo OR the transmitter has a lot of trim adjustment.
I'm experimenting with using Spektrum SRXL2 serial receiver and Spektrum DX8-G2 transmiter.
