This isn't igntition related but close enough to add here. There is another thread on FG about leaving the WiFi turned on with onboard gopro cameras and many, many crashes resulted from it. The theory seems to be that because the GP's WiFi transmitter is so close to the RX that it effectively swamps the entire spectrum and causes loss of control. A few FPV'ers chimed in with similar stories about quads doing similar or wacky things when the WiFi is turned on. I'd be interested in hearing the experts opinions on this and whether or not it relates to the topic here.
