Anafi 1.6.7, iPad Pro 9.7, Free Flight 6.6.6
I flew a test mission and then 10 mapping mission using Pix4D Capture.
I had no crashes, no loss of signal.
I did have some problems though.
I too experienced the strange fan noise. It did not happen every flight but it was there a couple of times upon landing.
Pix4d Capture works differently now though. It will Return to Home on its own when it gets to around 10-12% battery.
A couple of times when I took manual control or it returned to home for low battery it was still taking pictures and did so even as it landed.
2 times while flying autonomously, on its own it reverted to manual control and suddenly started to land without any input from me! This happened in the same exact area twice.
I thought the metadata was messed up, but it wasn't the numbering order and scheme of images was so messed up with being in the two different folders (100,101) that it took me some time to sort my images
For the first time ever there were two folders made to store my images, 100 and 101 and images that were taken hours apart were stored together sometimes. There were totally wrong dates and times assigned to pictures.
The Anafi held a strange angle while flying (It was 10-14 mph winds), but this has not happened before in winds when using Pix4D Capture.
I hope Pix 4D Capture has an update to match this new 1.6.7 or a new Parrot firmware is made. I have several large jobs coming up and it looks like I will have to go out tomorrow and refly the whole mission which I didnt even finish to begin with. I am going to have to charge my batteries on site tomorrow and hope for better results. I really do not want to have to use the Mavic 2 to map with, as the Anafi has much better results and the workflow is easier for me.
