Some of the Crazyflie 2.0 kits from our first batch contained badly balanced CCW-propellers. Even though they can be balanced to perform well according to this guide we decided to offer replacement CCW-propellers for anyone that got a unit from the first batch. Note that even if you have well balanced propellers it's always a good idea to balance them manually to achieve the best performance.
If you would like to receive a replacement pack of CCW-propellers then please fill in the form below. The information will be forwarded to Seeedstudio and they will ship the CCW-propellers after Chinese New Year. The information in the form will only be used for this purpose and will only be shared with Seeedstudio.
The serial that should be entered below is the unique serial of your Crazyflie 2.0. It can be aquired by finding the 24 character long USB id for the Crazyflie 2.0 when connecting it via USB. See this guide for finding the USB serial.
Please note:The packet only includes CCW propellers.
