receiver warning during one of my recent flights

    Hi Folks,

    Recently I was doing a flight in the vicinity of some pretty huge electrical transmission towers. I wasn't flying anywhere close to the actual wires but they where in sight behind me around a quarter mile away or so. My question is whether being this close to these hi tension power lines could disrupt my signal from receiver to transmitter.

    The reason I ask is because while flying I got a receiver error warning over my earphones. The copter seemed to still respond to my controls but I was wondering if this is something I should be careful of. I was flying out in the middle of the desert actually over the San Andreas Fault line and I could see the towers. I know that these kind of transmission lines can actually disrupt my cell phone communication when I am near but wonder if they could affect my transmitter and receiver and cause safety issues with flying in these areas.

    I'm just speculating, but yes, I wouldn't be at all surprised to see those power lines causing interference. They're sizzling with so much energy (and noise) and appear as a giant transmitting antenna. I'd avoid them like the plague.

    As to their effective "range" -- hard to say.

    It sounds like you were lucky that the Tx/Rx is digital -- it sounds like it still managed to "punch through" the noise, but only just.

    Hey David,
    Yes power lines can disrupt signal from receiver to transmitter, I have a X6 dragonflyer which almost took my head off flying close to power lines. Since I changed to cinestar and MK and flying on construction sites near power lines I have turned off the compass. Which has caused yaw problems and one fly away!! I flew over a crane once with compass on and it turned 180 degress on me and took off quite a scary experience. Be warned!

    I think this also the cause of crashing inside if you dont turn of compass with a MK.

    so if you do fly near those things turn off your compass and be prepared!!

    As I like to say to people '' IF I DUCK YOU BETTER RUN''
