I am being told that my problem with my quad lies within the control loops of the flight controller. That being said I am not able to fly my quad to tune it. So where do you start with tuning. Before I lengthened my arms and up'd my motor size from 2214 to 4114 the default values were "ok" at least to get the quad up in the air and get it tuned. The way mine sits now with the default values it is impossible to fly. Motors get hot and you have to constantly be correcting some kind of extreme movement.
I went from a 550 size to right at 750. Went from a 12in prop to a 15in prop. I reset the pixhawk back to default settings and reset everything up from scratch. I have not even touched the control loops It was always my understanding that the default PID's would be able to get the quad up in the air. Do I just need to set everything to zero and go from there?
