So have a Phantom 3 Advance. Bought in 2016 and it only has 15 hours on it. I am anxious to fly it more but deal with IMU error for the past year and sometimes it flies and sometimes it does not and no matter how many times I calibrate it is a hit or miss or I put it away until another day. So I am hoping her I can find the permanent solution and start flying again or just move on to a newer model. It is in excellent condition except this. Anybody have any ideas? Appreciate any and all help.
