They came well packaged, but with manual in Chinese. This is actually normal as I ordered the Asia-Version, because

In the first part of this tutorial I described which are the needed parts to build a quadcopter. Here I will try to explain the building process as simple as possible. Start with assembling your frame. Usually an assembly manual is included or you can download it. When you are ready with this step, then
