I know the this servo is digital. But maybe Airtronics super high frequency isn't compatible.
How much is it vibrating? I know this is a hard thing to describe.
From page 55 in the MT4 instruction book use the SSR mode for Airtronics SRG type servos and the SHR mode for all digital servos. set your servo for SHR mode or normal and this should work if not you have another issue with your RX. Michael
