We also had a Spectrum seriously effected by noise from an ignition module. Yes, the 2.4GHz units also follow the same laws of nature that the other radios do, they can be effected by electrical noise, it is just that there is not as much chance as for the 72/75 MHz units. As to one of the comments above that the radio might be getting swamped out because the transmitter is to close: if so I'd sure get me another receiver as this will not happen with a well designed receiver and power levels that our RC transmitters put out, especially the 2.4GHz units.
