that is already done by the original transmitter circuitry, to be replaced by the Arduino
Is it feasible?
Does anyone have any say about this? Is it feasible?
Interestingly, if the signal is already produced by some circuit, it makes little sense to switch to a microcontroller.
As for the nRF24L01 I don't think it will have the same transmitter power as the original radio system devised for flying RC planes.
