Yes, but most flight controllers can accept Spektrum receivers directly. If yours doesn't, then you could use the X10+ with one or two Spektrum satellite receivers.
Hi Jim thanks for the reply
I am actually interested in more channels for gimbal, camera, retractable landing gear and so on.
You know You spend the money for a 18 channel transmitter but the give You a 9 channel receiver.
I am thinking about using 2 X10+
