I'm having a similar issue as others, I installed new ESC's today ( little bee 20A B-heli ) and for some reason the Transmitter is now as good as dead ( TGY-i6)-( TGY-iA6)
The motors all work, and can be calibrated via the LibrePilot wizard, but when it comes to the TX setup, nothing happens.
I've done a full refresh of the CC3D a couple times, and gone through the wizard from the start a few times. Seems to work fine.
Then I tried re-Binding the TX and RX , which never completes just says ( Binding.....) and never progresses.
Though when I restart, the TX does show up on the RX screen with flashing low battery, and the LED on it is shining solid red which I believe means it's paired.
I did notice in the Controller Configuration screen, where it has the options for ( Type, Number, Values )
The numbers where set to zero, I tried matching these to my stick control channels, didn't do anything.
If this is the same problem you guys were having I'd love to hear what the fix was in a bit more detail.
cheers.
