I have the Phantom 1.1.1. I'm sure the little gimbal lever is turning the potentiometer in the TX. However in the Naza software there is no Gimbal information (IMU or CMU): Like this screenshot of another user shows: Mine just shows: Also the Gimbal calibration in Naza under Basic --> R/C --> Sticks monitor --> X1 does not register any inputs Turning Gimbal on or off on Advanced --> Gimbal makes no difference. I was about to by a Zenmuse for this Phantom 1.1.1. but now I'm wondering if the Gimbal is broken? PS: I can confirm the inside of the TX is the one labelled "new circuit" in this image. Thanks for any help people.
