| + | Before you go ahead and assemble the Crazyflie check the Crazyflie control board and the Crazyradio electronics: | ||
| + | {{: | ||
| + | |||
| + | 1. Attach a powered micro-USB cable to the Crazyflie control board. It should power up and blink 5 times with the green LED. After that the green LED should be fully on and the red LED should blink. | ||

| + | 2. Attach the Crazyradio to a computer and follow the [[http:// | ||
| + | |||
| + | 3. When the cf-client is installed and the Crazyradio is working it should be possible to connect to the Crazyflie using the connect button in cf-client. Test that you can connect. It is also a good time to update the firmware now using the [[http:// | ||
| + | |||
| + | When all these tests passed go ahead and start the assembly. If they did not pass visit the forum and open a support thread if you can't already find one describing the problem. | ||

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 " |

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**.

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 (carefully push in the button with your fingernail - it is **not** a slide switch) |

| - | ====== Maximizing performance ====== | ||
| - | To get the best performance out of the Crazyflie we recommend you to optimize it. Below you will find some tips | ||
| - | === Balancing propellers === | ||
| - | {{: | ||
| - | Vibration is one of the biggest reasons the Crazyflie performance is degraded. Vibration effect the gyro and accelerometer measurements making them more noisy and inaccurate. Vibration is mainly caused by unbalanced propellers but can be caused by a bent motor axis as well. Balancing these small propellers is extremely hard and we are still searching for a good way to do it. An easier way to get balanced propellers are to sort them and categorize them according to their vibration. This can easily be done by using the spare motor and a normal 1.5V AA battery to power it while testing each propeller. After this has been done use the propellers with the least vibrations. | ||
