ADDED: I just noticed you said you too off with GPS lock.
ERR Subsystem 10 is "failed to enter flight mode." Double check that you didn't take off in sport mode? If you did take off in sport mode and then at any point tried to switch to fly mode, then you could get some crazy flight characteristics. You must have GPS lock before flying but you obviously know this.
With DIY Pixhawk builds it would be standard practice to obtain GPS lock, take off in a GPS mode and switch to sport/across. This way, if a failsafe kicks in it will know where to go.
The right thing to do would be to build a non-gps unit to fly in acro/sport. The Solo was never really intended to fly in sport mode. You can do it because it is built on the Pixhawk but it's more of a video craft.
Just saw this. I always take off in GPS mode and make sure it has a lock on take off position. Even if it says it's safe to take off, I still wait a minute while I am setting up. I always let it hover to make sure it's stable for awhile, as well as quick control checks. I've always done this on all my quads, and probably why I have never crashed any including a bunch of Inspires I flew for work. I fly a lot of manual mode as well on the DJI's.
I was flying around a few minutes in loiter, when I then let it sit and hover for about 10 seconds I selected "Sport" in Solex. That's when it immediately went at least 45 degrees AOA (which I think 45 is limit in Sport?) and I heard the motors go full throttle. I tried to correct it but, it completely ignored me. The err Subsystem I think is when I put it back in "Loiter" but yeah, obviously didn't take that either. This all happened in about 10 seconds.
It's just cosmetic damage at this point on motor 2 and the arm. Not really sure how to fix the road rash on it at this point.
