Step 4: Connect power and ESC leads to the Flight Controller
Identify the top and bottom of the Omnibus Mini F3 flight controller. The top is the side with the
USB port and the directional arrow which indicates the front. Turn the flight controller over and
solder the power leads that you soldered to the battery leads in Step 3 to the B+ and B- pads on
the bottom of the flight controller. In our example, the positive lead is orange and should be
soldered to the B+ pad. The black lead is ground and is soldered to the B- pad.
