The simplest way to do so would take the information that comes from potentiometers (analogRead between 0 and 1023) and send it immediately by nRF24L01, right.?
From my experience, even in close range you will get some loss of signal. nRF24L01 data links are not reliable for transmission ranges larger than about 2-3m and if there is no direct line of sight between the transceivers. (That's probably why these units feature the autotransmission ability.)
