RE: Electric HT wires interference with RC signal
HT wires WILL cause RF problems if you fly too close to them. I have a 765,000 volt AC line close by and you can turn on your radio and the servos will dance like crazy if you are within 50 feet of it. Park your car under them - get out and try to get back in - you will get a VERY nasty shock from induction. So stay away from them.
