- | 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. | + | Vibration is one of the biggest reasons the Crazyflie performance is degraded.

- | Your copter is facing forward when both the red and green LED are doing so. However, that might be a bit difficult to determine, especially if you are looking at your copter from below (since it's flying higher than your heade). To compensate for that you might want to mark the motor arm of M1 with some colored tape. | + | Your copter is facing forward when both the red and green LED are doing so.

The Crazyflie tries to hold its yaw orientation (rotation) steady based on feedback from its gyro. The orientation it's in when starting up is the one it will try to hold (unless changed via yaw inputs), so power it on in the orientation you want to fly it in. For beginners, that's almost always facing the same direction as you are, so that your pitch/roll joystick inputs line up with the physical direction the Crazyflie moves in. So, put it on the ground with the power switch in the front right corner and turn it on. | The Crazyflie tries to hold its yaw orientation (rotation) steady based on feedback from its gyro.
