Ok. So I fly my quad. Everything was fine. The next day I went to fly again but the fc red led was flashing constantly. No response from the tx to the rx. Got in betaflight. Shown no response from the sticks.

Quad 1: spracingf3 with i6x rx
Quad2: lumineer lux v2 with the flysky i6b
Same problem both quads. Any help is appreciated.

Have you tried to rebind?

Yea I have resound both rx's. Flashed newest firmware and tried 3.5 firmware.

Can't be a coincidence that both your quad were working and then stopped. Sounds like a radio problem.

When you reflash the FC firmware, did you properly setup? You can post dump and how you wired for us to check.

Yea I have the urt3 serial on and the rx set to serial and ibus. That's for the sp racing fc. I have also tried with ppl and set the tx for it as well but still same results. I'll post the dump in a minute.

i have the wire to the io2 port going to the ibus port on my tx. for the sp racingf3

i know with the frsky rx's that you can enter a mode that cuts its ablity to recieve from tx. is the x6b tx from flysky the same. if so that may be my problem.

Assuming that you correctly wire IBUS from receiver to RX3 on FC, then your settings are correct.

I don't think there is any mode you can change in the X6B that would cause the receiver to stop working.

It is really odd that two quads stopped working. My guess is your radio. Do you know anyone else with Flysky you can try testing?

I figured it put my spracingf3 is fried on one quad and my rx on the other is fried. Put lux v2 on with the working rx and now I got one quad up and going. Thanks for the suggestion.

How did you figure this out? Now you know it is not your radio.

This hobby is so full of those it's ridiculous lol Makes trouble shooting a NIGHTMARE!

Turns out it wasn't the radio either SMH..... that was almost CERTAINLY the issue too.... how does this keep happening 

Just another day in the opposite of the star wars universe.... where there is ALWAYS such thing as coincidence
