Hi. I got my IRIS+ about two months ago and had about 20 great flights with it. But two days ago the big troubles suddenly came up. I had two crashes, the first with just a prop damage, the second was far worse with a broken arm and two broken long legs.
1st crash:
I was flying for about 12 minutes when the copter suddenly started drifting strongly towards a building near it. I tried to pull to the oposite side but then it started turning, I again gave it full power to the opposite, managed to get it away from the building while it was going downwards strongly and hit the ground. As I already mentioned the damage was not so big. I replaced the props and went on to the second flight. This all happened out of LOITR Mode.
2nd crash:
After the first crash I had a short flight where I felt the quad drifting a bit too much and let it land, then I started flight nr. 24, flew around in STD mode, went up to about 100m and made a couple of overhead shots of the area. Then I put it in return to home to see if everything was good in that area. IRIS+ went up a bit, came back to the starting-point area and started descending. At about 4m height I put it back in STD mode, because I wanted to land it safely. At about 1,5m height (so almost "home"), it started drifting to one side (no wind), I pushed the right stick a bit, and a bit more, and more, until it was fully to the side to keep the IRIS+ in the same place, then it held position for a couple of seconds and after that it went into suicide mode... up to about 3m, started spinning around, not reacting to my commands at all and crashed about 20m away pretty dramatically. The result is one broke arm and two broken long legs - I have no clue if the gimbal is ok - I hope so!
It would be great if someone who has the expertise could look into the log files and tell me what could have happened. I am posting Log files 22&24. nr. 23 was no crash, just a short flight (if needed, I can post it).
thank you!
