Hi David hope your well, I have done range test with the 9ch temporally plugged into my extra but with both antennas screwed into the existing two patch antennas in the aircraft etc. I have not yet set up program so just had rudder set up so I could do range test etc the only issue on the core whilst conducting the range test is you cannot view the RSSI figures or LQ etc which is a shame. With the range I got under test condition I would have no problem in flying with the 9ch Rx hooked up to the patch antennas. Richard did tell me that they have made the Rx more sensitive and he did not know if patch would improve or not etc but he did ask me for results which I have told him the results of ground range tests. Should not be to many weeks before I get chance to change over completely.

I have installed my Core for test in a Elan I brought for testing etc and have a mercury SRS with PBR26 and it had first flight the other day with everything being fine.
Going to install another Mercury SRS and 2 x PBR26 and CTU unit in my T1 jet also installing Power Expander with PBR26 feeding Powerbox into CARF Hawk...

I am still flying my Graupner MX24s with DV4 module with all four wires internal going up inside of mounting shaft ie no external patch lead at all, this also working faultless.

I really like the CORE!
