"I've run a dozen models through Pix4D mapper now but would still consider myself a beginner. What types of things are you wanting to learn? I am also interested in the 3DR X8-M."

Mark Brown replied to Daniel Paez's discussion new start with the ebee by Sensefly
"Yes they seem to be really affected by the wind. It looks like if you're heading into and away from the wind then the spacing can be really pronounced. Out of interest are you processing eBee data in Agisoft Photoscan? I thought it was only possible…"
