Hi everyone, I am planning on a surprise present for my girlfriend on our anniversary day. The idea is to tie a gift to the drone and I would control it from a distance around 50meters. The area is clear with no interferance with the crowd. So I basically need to fly it straight forward from where I am standing to the other pount without any manouver required. It is pretty much flying in a straight line. What I am wondering are what are the height I should go for and what is the suitable carry weight the phantom 2 vision + v3 can bear? I am looking about 300 grams of carry weight. Please advise me on the maximum load or would it cause any damages to my drone? Thanks so much guys!
