    The manual isn't clear..what wire colors shoukd be coming out from the gimbal to the transmitter receiver. Is it just the white wire and where does that plug into relative to the transmitter receiver..meaning the polarity?

    There are 2 wires for every "channel". Ground + signal. Usually the GND is black and signal is white. You can't do any damage if you swap GND and signal wires... The only important thing is to remember that you MUST NOT connect anything to the middle pin on the 3 pin receiver cable which is always used for +5V.

    Okay thanks...yeah the red should be disconnected and just plug the black and white...I wanted to get this confirmed b4 I did anything. Thanks...

    What exactly is horizon drift? I wanna see if I have this issue. Is it just that it doesn't hold the horizon parallel to the ground?

    yes, horizon doesn't hold.. especially when yawing quickly...
    This is my test with 1.20 firmware, it was really bad at that time:


    fortunately in the latest software (1.22) it works much better.

    Question....I connected the tilt signal wire from the gimbal to my TX but it controls the roll...I got the wires mixed up right?

    Just came across this thread, nice to see that someone else tryed to put the g3 on a qav400.

    Since I travel a lot i needed a small size fitting gimbal like the g3 it fits perfectly, and looks very nice (my opinion)!
