Just recently began having 5.8ghz signal loss to ST16s, but never any RC control issues, always fly LOS and have been able to pilot back to base very easily. Recently upgraded to a 4hawks XR range extender thinking this would solve the issue, however, I suddenly began losing RC control (2.4ghz) at about 1000 ft distance and 150ft of altitude, this was a complete shock to me. Fortunately I was able to walk back into range and land safely, I mainly fly in open acreage so have no LOS issues, has anyone experienced anything similar?
