On the subject of flashing lights I have installed the Spectrum module in my JR9x11 when I turn on the TX then RX the RX lights are solid, now if I turn off the RX and turn it on again with out turning of the TX the light flash but still seem to have full control I have not made a flight under these conditions, So am I right to assume that if you turn off your RX for any reason you should also turn off your TX with this system.
