With the telemetry I find it very helpful to do the range test while monitoring the receiver data link data at the transmitter. Since I always test well beyond the recommended 30 paces it is sometimes difficult to tell if the control surfaces are not moving properly due to signal problems. With the live telemetry I can see more data in real time than I can with a flying buddy watching the airplane while I walk with the transmitter. It is interesting to have someone rotate the model through all orientations while you watch the per receiver data. I never grant full trust to a radio system until I slowly build a basis for confidence in the installation and equipment.

By having live telemetry on the quality of the data link this is much faster, easier, and safer than my old land the model and check the data log before flying it again to greater distances.

Yeah, you don't need it but it sure is nice.
