I don't get any glitches and my battery pack is within 1" of the CH box. Both the ign pack and the radio pack and receivers are right together and right beside the module but this is with a Spektrum radio. I have three planes with the receivers less than 2" away from the ign module and the one plane with the battery packs near as well. None of them glitch at all. Again that is with a Spektrum. My G26 powered, CH ignitioned, Spacewalker was on 72 MHz before I bought the Spektrum and the receiver and one pack were within 2", at that time, of the module also without ever having a glitch. The radio was a 7C Futaba on channel 22 and it was a PCM receiver.
