+. Attach the propellers (see drawings below for mapping). :!: You got two **different** packs of them with your kit, one with five clockwise and one with five counter-clockwise ones, take care to really use propellers from both packages, not just mounting two of them upside down, your drone won't fly otherwise :!:. Your clockwise propellers may be labeled with an "A", otherwise look at the curvature of the tips to determine which is CW and which is CCW. The dull surface goes up, the shiny surface goes down. You will also see a small molded ring on the top surface. We recommend you sorting out the best propellers.

-. Before you power it on **visually inspect your soldering for shorts**. Make sure any copper from the wires are not sticking out so they could short to **either of the two resistors next to M3 or to anything else**. You can also use a ohmmeter to check for a resistance of about 2 ohms between each pair of pads. After that power on and check that all motors spin during start-up and in the correct direction.
