Accessing the hardware platform
There are many ways to approach the enabling of your quadcopter platform. One way is to build it from scratch.

You'll use the Parrot 2.0 quadcopter platform, available from many different online retailers. Here is an image of it:
One of the key advantages of using Parrot 2.0 is that it uses a standard WLAN access point as a control interface; your Raspberry Pi can easily access this to gain control. That's it! You've got your hardware platform.
