Hello everyone
I have fs-i6 transmitter and receiver And have a CC3D flight controller
I have a problem connecting my receiver with the transmitter as it is not displaying the receiver voltage on the transmitter display.. It would be really helpful if you can guide me..

What receiver you have. I think its not i6B receiver.

Actually the transmitter and the receiver were working fine bofore
The problem arised after some usage of my CC3D so I even changed my flight controller the problem was the same my transmitter was not receiving signals from my receiver..

Any  indications in the rx , while tx on or off

Yes I do have indications
When I connect battery with my rx and simultaneously when the tx is off the rx blinks
After that when I switch on my tx my rx gives a constant light which clearly means that it's connected still it doesn't show up on my tx

What if I purchase a new receiver of the same tx model

It would be better idea to buy a new receiver. If still it doesn't work then problem is with transmitter antenna. If it worked then it would be receiver antenna problem.

Okay I'll order a new one..
Thanks a lot
