I've posted about this on several other places to no avail. Long story short, my Naza-M v2 is not holding my Tx calibration settings. Get an error code 29 when I hook it up. Takes 2-3 times before actually recognizes the stick signal properly (but only on particular stick). Seems to only hold it for a short period after I re-calibrate (like less than 24 hours). If I go out and immediately fly, it works fine. I've tried it later on, I can get it to start and give it throttle to lift off, but otherwise it doesn't do what I need/want it to. Any ideas?
