CUAV C-RTK2 HP dual antenna RTK GPS

I have been working on a robot mower and tried the LC29 RTK GPS with results that were just kinda OK. Wondering to upgrade to CUAV C-RTK2 HP. Specs are awesome. .2 degrees yaw accuracy, quick capture of GPS data. Two antennas, one GPS chip, Comes with RM3100 compass and both helical antennas. Price is far better than dual F9P’s. Apparently supported by ardupilot and bench tested by Yuri, but few if any field reports about the unit on actual rovers. Does anyone have experience with this unit? Not sure what chip it uses: doesn’t seem to be the Ublox or UM982. Support? The product is pretty new: 8/23. Thought I’d open a new thread to gather some information. I’m still pretty new to this so if there are other threads I missed or this should be moved, let me know.
