Go to the last 45 seconds for the....er... crash: Well... this is the reason I fly w/ professionals... I recommend you do NOT fly backwards... and avoid EVER losing visual contact w/ a drone you are flying, even if you know the terrain very well and scout it... even if you have a fancy little map on a great little app... ultimately I crossed my signals and went left instead of RIGHT... and that was it... then I still had signal and instead of walking through the snow kneed deep ... I got lazy and tried my luck? The damage: luckily only 4 propellers ;) ALWAYS DRONE RESPONSIBLY. Remember that you can hurt others if you make a mistake... so nice open, empty places and low altitudes are more than enough fun!
