"The problem we have like many others is access to take GCP's. We work extensively on saltmarsh and mudflats so you can imagine how this tech would be a game changer.  "

Flight Time.

Hi Guys,I'm only getting 9 mins max of flight time from my Solo. 3dr says put SYSID_SW_MREV parameter to 0 then recalibrate and reboot so I do and I still get 8-9 mins. Had a look at "BATT_CAPACITY" and it reads 3435 mAh not 5200, so I change it to 5200 and then write to drone, but as soon as I restart Solo it has reverted back to 3435. Can anyone suggest what is happening here as I am defiantly writing the param to drone? Thanks.See More

"Great stuff, I have converted a ixus 220 and have been able to produce some images. I have found that getting the white balance correct is most important. This image is of a salt marsh, muddy creek, sea wall plus an oil seed rape field which…"

"I'm wondering what photogrammetry software would you use for such a large project?  Can Pix4d, Photoscan etc. handle this kind of large dataset.?"
