Had my first loss of control today flying outside a building.
In this, I'm just climbing - no input on the right stick at all. At some point, my solo starts moving to the right for no apparent reason. I didn't get any GPS loss or loss of controller signal error, and video was streaming the whole time (that's how I noticed it was moving).
I can tell I wasn't accidentally hammering the right stick because it's moving faster than the slow max speed I had set in the app before hand.
I hit the pause button and it did brake (you see that on the right side). I then hit fly to return to fly mode, and brought it down for a manual landing.
Happy this happened in open air so it didn't smash into anything, but a little worried it might happen again - also just in general I tend to get random controller signal loss near this building, triggering a RTH, but within seconds I regain the signal and can go back into fly mode.
Should I be re-aligning the stock antennas on my controller? It seems to be worst when it's directly above me, particularly over 200 feet.
