The only negative is the lack of decent printed instructions. You have to go online to get the pdf manual, which is nt much help if you are out in the field. I had trouble getting it to go very far or high, and i scoured the web for advice to overcome the limits. I tried updating the firmware twice and removed and reinstalled the app before discovering the problem. If you put the propeller guards on, it goes into payload mode, take them off and it will go as far as you set for height and distance, bear in mind that it is legally limited to 400 of altitude and within sight horizontally. But that is fine.
