I had two close call during my first days of flying:
Incident 1: I took off from a picnic-table (deep snow elsewhere), and after just a minute a got a compass-error and the bird went into into Atti-mode. Immediately it started to drift a lot, there was windy and nowhere else to land it then the picnic-table I had taken off from. Because of the lack of experience, forces atti-mode and wind I really had to struggle to land it. I was also very close to smash it into different obstacles.
Lessons learned:
- Don't take off/land on objects that may have some metal in it that can interfere with the compass.
- Beware of the wind!
- Practice Atti-mode as soon as possible, fortunately I had some practice with smaller quads, and that saved.
- Have a large landing-area, with as little obstacles as possible. Hand-catch in atti-mode and wind can be risky/not possible.
Incident 2: I was flying just outside my house, and was about to finish the flight. Again it was a bit windy, and the bird was about 150 feet / 50 m up inn the air. I descended at full throttle, and just releases the stick when the bird was about 2 m/ 6 feet in the air, and about the same distance from the walls of my house. As i release the "descending-stick" it immediately started to drift against my house (in other word, did not lock possession/hover as expected) with the left side against the wall. I kind of freaked out, but was able to turn the back against the wall, and fly it away just before it smashed in the wall. I was flying in P-GPS mode.
I'm not sure what happened here, but I believe that maybe the GPS-lock on possession get's released for a brief moment when to let go of the stick? My other theory is that the drone trying to compensate for the wind(to hold pos) on decending, and when it get in "shelter" for my house, it kind of over-compensate, and drifts a bit.
Lessons learned:
- Beware of the wind and possible drifting when releasing the sticks, even in GPS-mode.
