Spektrum SPM9745 are not working with Mercury SRS, binds but no servo movement

  • I am having a problem with the Mercury SRS (version 08) and spektrum SPM9745 satellites. I have 2 satelites plugged into rx port 1 and 4. The frame rate is set to 22 and I have tried both DSMX and DSMX18 mode. I am able to bind both satellites and see the solid orange light.

    However, I am not getting any response from he servos, it appears they are not getting transmitter input.

    What could be the problem here? It is not a binding issue as the TX clearly says the satellites have been bound on 22ms mode.
