Hi, After doing all initial calibrations, my transmitter's A channel reports a value of 12 instead of zero like the others. This has a potential to have the craft drift when idle, or does it? I also did the manual transmitter calibration DJI posted that doesn't require the assistant software several times successfully, but I still get a value of 12. If you look at the arrow in the software, it is on the middle line but on the other edge of the other channels. Does anyone know how to adjust this by moving the screws? There sure are a lot of screws around the sticks. Thanks!!
