Buying a Black Pearl monitor and the one I'm looking at is the SMA version from Troybuilt and I we planning on using a Fatshark TX but now I've decided not to pay that much for Fatshark. The sales person is telling me they pay Flysight to build the monitors differently and that this SMA monitor is the 32 channel. On other sites it says the 32 channel is the RP-SMA. Not sure what to believe because what he's telling me is contradictive. Please help me.
