Hello,

I try to use and independant Futaba receiver on my Z15 gimbal.

If the gimbal is not connected on lightbridge all is ok, if Lightbridge air module is on, it's take hand on control and i can't use my idependant receiver.

I try to unmap channels 9 - 16 on Lightbridge assistant but no change.

Any idea how to made this setup

How are your channels mapped on your FC?  I would also unmap them on you Tx.  You independent Rx for the gimbal should be 5.8gHz to avoid interference from the Lightbridge.

I've unmapped channels 9-16 (secondary RC) on lightbridge assistant.
Unmapped also from primary TX
It's not an interference, if i disconnect G7 cable from Z15 and to lightbridge it's works
