Eugn,
Ihave done a number of full antenna up range tests using a JR10X with 955 pcm-s receiver - ground range was generally around .6 mile. Of cource this would increase with elevation of airplane. Lots of things can affect range- I would not feel comfortable going much further out than the ground range noted above. Anyhow at .6 miles I could never see my airplane- we used cell phones for the range testing.
Good Luck with your project,
Al
