Ahh ..... thanks for sharing! Great flight and a great lesson about taking off backwards. I am about to try that.i flew it from the balcony where I am standing, flew it backward very carefully cause Im afraid to hit the columns.. as I was about to return it back, I wanted to fly it towards me, it wont pass through because obstacle avoidance is sensing the two columns, i dont know how to turn of the obstacle avoidance that time so I panicked and had to flew it over the back towards the entrance of our room. Later on after landing, i then realized i should have flown it backwards towards me ..
your welcome mate! I will be waiting for your video
btw, I uploaded this in 4k, at first i thought Youtube compressed it to 1080p, but you just have to wait for a while before you can see the 4k option while watching the vid.. it took like 4 hrs after upload before i can watch it in 4k.. cheers
