I have an XA hexa but it currently has a WK-M on it. I also have a Naza, but it is on a F450 frame. On my Hexa, I have the WK-M's basic gains set to 130%, 130%, 140% and 110%. The Attitude gains are both set at 85%.
Im running the X aircraft Hexa w/ 30 amp DJI ESC's. 900kv tiger Motors. 10x47 props. CM130 camera mount w/Go Pro. Im not rock solid yet but im getting there. How is yours going? Gain settings maybe? Im not far off from stock right now.
