Rookie MA2 owner, decided to fly around the sunset time. Started off good but when it got darker there were warnings about no vision systems because of low light, guess I did not comprehend the significance of it at the time (or what can happen down the road). It was all good until landing. I cancelled auto landing because the AC tried to land about 4-6ft off from the take-off location. I tried to bring it in to land manually at the back porch of my unit. I got it down to knee level and tried to position over a landing pad, which turned out to be a mistake (should have landed immediately in retrospect). I tried to position it perfectly by flying to the side, but it kept going - did not stop when I released the stick. I corrected so it wouldn't hit a glass slider door but it did not stop either and "fortunately" the propellers hit my shorts just above the knee level. The AC fell down onto a weather-beaten wooden decking. It ended up "perfectly" onto all 4 legs, all propellers were folded, it was still powered on and I had the picture on the phone screen. I powered it off. I realized later it must have lost the GPS (no wonder that close to the building) and (with no vision systems) switched to ATTI mode. Can anyone please confirm that this is in fact what happened? Logs are attached. Did I miss the warning (about ATTI mode) in the DJI Fly app or there wasn't one? I was looking at the AC trying to position it.... There are no obvious signs of damage to either propellers or the body. What should I check before flying it again? Thank you for all the help.
