So flying the XSP yesterday and noted that it was erratic, I mean the drone was literally flying in a 360 deg flight, I flew it higher at around 75 feet before it flew steady. Brought the bird down and it landed (not sure if it was my backyard being uneven) after landing it tilted on it's front shutting down the 2 rotors right away. Now I crashed this on some bushes two days prior and I had the low battery incident almost losing the drone all together about 1 week ago. I re-calibrated the compass every time I fly, but still doing to tilt to the ground after landing. So far, I've landing it on grass/dirt. I am afraid to land it on concrete/asphalt because I don't want to break the propellers. I re-updated the firmware last night - have not flown it yet, but I'll try the concrete landing today really carefully. Any thoughts???
