I am trying to arm my pixhawk and I keep failing the check for the 3D fix. However, I do not have a GPS module plugged into the pixhawk and I am just trying to use RC control. My question is, how do I edit Prearm checklist to remove the GPS feature? Also, how does my quad know it will be controlled with RC, because right now I believe it wants to be controlled autonomously.
My professor gave me this pixhawk and I'm not sure what they were using it for before I got it. Any help would be greatly appreciated.
