Greetings fellow pilots! I may have posted a thread about this issue before. I searched the topic however and did not find one. I have never crashed this drone, but I have experienced several hard landings. it seems as though this drone does not detect it's altitude very dependably as my DJI drones always do. In the beginning i was landing with the left stick. After talking with support i started use the land/launch button on the control. This did not help. I contacted support again and they have not supplied any helpful advice. I suspect that the downward facing sensor does not see an obvious surface, therefore I have spent much time and money trying to create one. I purchased a 2ft square plywood board and painter it bright yellow with contrasting dark green lines in a crossed pattern (Non-Gloss). Although I think this helped I still get hard landings. Support has ignored my latest request for help so I think there is really no fix for this. It is a weakness in the hardware that they rather not discuss. Have any of you experienced this same problem? I think this problem is causing other issues and will eventually kill the drone.
