The new 5.06 firmware is not performing as well as 5.02, I am going back.
I have worse gps acquisition and position hold, the wobble in anything but dead calm is still there and the gimbal now twitches even more (not that it was usable before).
I too have a YS-X6 coming in hope that I can retire the WKm.
What airframe are you using for that test?
