This has been a very informative thread even with the banter. I have to say from my understanding of 2.4 that I agree with dirtybird. The areas of interference, by the discussions here anyway, have been by a means that is bypassing the 2.4 system, not going thru it. The "2.4" is the transmission of signal between the Tx and the Rx through the airways. Everything else such as servos, ign's, etc, is not a 2.4 signal. Digital or analog yes but not a band, therefore one can not say that a twitching servo is caused by interference of the 2.4 system. Merely that is the perception from a lack of understanding and a true cause will be found within the electronics outside of the Tx to Rx 2.4 transmission.
