Herelink as standalone telemetry

I am using Herelink as stand alone telemetry , and Futaba as main controller, on Xuav talon plane, running 4.0.9 firmware. Issue is when I am flying with in range of 200m, plane is going for a failsafe, stating no receiver and but telemetry is there, when I hit RTL, plane nearing home point in loiter, controller is not regaining back the connection, I was forced to land using a emergency way point to land, I am confused in this setup any comments on this would be helpful. Attach the flight log for the same.


What is the frequency of your Futaba? Is the receiver close to the Herelink air unit?
