This page has details about how to assemble the Crazyflie nano quadcopter kit.

• Crazyflie control board
• 5 x motor mounts (one as spare)
• 5 x coreless motors (one as spare)
• 5 x CW propellers
• 5 x CCW propellers
• 1 LiPo battery

• Soldering iron and solder
• Scissors
• Tweezers and a clamp or third-hand can come in handy

1. Check that you have everything that's needed

2. Twist the two motor wires together so they are easier to handle

3. Thread the twisted motor wires through the motor mount arm section. I can be a bit tricky so have patience.

4. Insert the motor into the motor mount and be careful to not damage the motor wires while inserting it.

5. Press the motor mount on to the PCB arm. Be careful not to damage the wires when you do it. Start with M1.

6. Try to attach the peeled end of the motor wire into the motor through hole pad. Start with white wire on round pad on M1.

7. Turn the PCB around carefully not removing the wire from the hole and solder it from the top of the PCB. The square pads can take a bit longer to heat up as they are connected to the battery supply copper plane.

8. Repeat step 2-7 for the rest of the arms M2, M3 and M4.

9. Attach the propellers (see drawings below for mapping). We recommend you sorting out the best propellers. See maximizing performance

10. Attach the battery and try to centre the weight on the PCB as good as you can.

11. 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. After that power on and check that all motors spin during start-up and in the correct direction.

The following images show how to solder the motors and attach the propellers. The black pads should have the black wire attached and the white pads should have the white wire attached.
