Anyone have experience with the effects of flying in proximity with high tension power lines? I have an incredible ocean/wildlife scenery location in mind to fly, but there are high voltage aerial cables strung up to service the islands within 200 feet of where I'd hope to fly. Would really appreciate any info or opinions on how far away from the cables is prudent to be without the nav/gps going all to heck. I'd rather not watch my P3P go swimming in a 6 knot tidal river. Thanks!
