Although it looked like a range problem, it was never was. It was a firmware problem in the RF board that was causing the receiver go through a very fast failsafe and then reconnect. FrSky got on the problem very quickly and had a fix in firmware release 1.2.20. October 28, 2016. It was highly intermittent and I never experienced the problem.
The Horus X12S is an amazing system.
