I returned my new MA2 after a month of joy. In the last flight I almost destroy it but luckily after a mid air disconnection and an auto rth it don't land in a very insecure area and hover inches from a cement column until I can climb to a second floor and catch it. After uploading a few of the last flights to airdata i saw that there was very poor signal strength all the time in all that last flights. First ones have good signal strength. It appear that finally the disconnection was complete and I almost lost 800 bucks. Luckily I was only few days after my return window but Drones Nerds accept my return. Great Seller!! I strongly recommend them and also recommend AirData to be aware of the Signal Map of your flights. I had no clue of that poor signal strength in the app...
