Thanks Keith, I will try this method as the YouTube video explainer doesn't work for me.

Can anyone shed any light on my problem. I have Aurora 9 TX and Optima 7 RX on my DJI F550 . Following the detailed instructions on YouTube I get a red light on the transmitter with a blue flashing light but not on the receiver , where I just get a red light with NO blue. Any ideas ?

Hi, I'm not new to RC flight but want to relight my interest after a brak of 10 years. My DJI S800 and F550 both need some work and I'd like some help as much has been forgottoen in the past few years.
