The DJI with ND filter makes a great difference on a sunny day, with vibrant colours & a wonderfull looking sky. The edges of the picture from the Yuneec seem a little more distorted compared to that of the DJI's, also with a little more curvy horizon.
I sent an email to @YuneecAviation customer services about the gimbal issue but had no reply yet. I think the Yuneec camera footage could be as good the P3 with a few tweeks, but it isn't at the moment. I use the P3 and Inspire for work, but don't feel the Yuneec is up to the task or paid work the way it is now. It looks the part, but doesn't do the job as well. I do really like it though, so hope they will improve it over time.
