Crashed and was able to repair the rest but what looks like a resistor or capacitor broke off...any help identifying this so I can replace would be a great help
It's a resistor. You managed to find the one part whose value isn't labeled in the schematic.
Tomorrow I can tell you the value. I'd hazard a guess now that it's 2.2K ohm.
It controls the power getting to the gimbal.
I am getting 2.4k on mine with the component in place. 2.2-2.4 tomato-tomatoe. Take your pick. The battery smart leads can be soldered straight to the resistors on the board, just do it quick so you dont lift them.
