One of our members, fantomas, has worked on an updated version of the User Manual for the P3P and P3A. It looks like it was updated again in late December. The official manual from DJI is quite skinny and lacking compared to this one. He has gone to great lengths to make it more clear and complete. It is an essential download for every new operator, and even us older flyers.
