This also applies to other things. I fly at a farm my dad raises cattle. When I first started flying I noticed glitches over certain areas of the electric fence. It wasn't as bad as you decribed and it usually only lasted about two seconds and most of the time I could not recreate it. Because of this I stopped having my landing approach go over them and I don't fly anything over a 10 size plane by them at all. I haven't flown with the 2.4ghz by them yet so I don't know if it would still be a problem. But then again I aint gonna try it to find out.-BW
