Thanks mr.rc-cam-RCU
It is at the limits of this brain for comprehension but it makes sense.
I do not think that you will find that decent quality modern 72Mhz R/C Tx's have reduced range.
I have read about the collapsed antenna and 50ft for test. Assuming this is for "as far as you can see", what if you go 100ft.........?
Is there a direct ratio (or sort of) to collapsed antenna feet = Tx distance?
THAT would be WAY too easy. Though I'd ask anyway. As you can tell I'm not in a club and no "old timers" to ask. I'll walk back 50 ft and put the Tx behind me also. On a full charge it won't matter, but after a while it will lose the signal if you put it behind your back. This tells me in this primative test there may be a way to determine how far out your plane can go.
Whad ya think?
