Sorry, the only servos that will work on a modern MGL EFIS are those made by MGL. On older MGL EFIS systems you could also use Trio servos as Trio made their protocol available to use.
With the current EFIS systems MGL went with a CAN bus to connect to almost all systems and peripherals, including the servos. While the MGL CAN protocol is available in public domain I am not aware of any third party servos able to understand it.
