What Akschu said is completely correct. It depends on the phone, transmitter and reciever. Same phone, same transmitter, but a different heli on a pcm reciever I haven't seen a problem. But I know for certain, that with my particular setup, on those 2 particular days I got hit because of the phone recieving a text message once and a call once. I haven't tried to duplicate it, but I may do so one night this week after work, set everything up in the driveway with the motor off and give it a shot.

If I still had access to all the cool toys I got to play with in the Navy I could conduct some serious testing on the issue.

But the point I am trying to make, is while it may not bother most of the people most of the time, you cannot dismiss it out of hand as impossible.
