Here is a quick photo of my Code black (Hubsan x4 H107C HD) drone, with my car keys to show it's size in real life. Notice the motor on the deck after I cack handily managed to rip the thing out of the chassis while trying to remove the prop (A video tutorial showing how to replace the motor has been uploaded).

I have also included a photo of the crash pack I bought from Amazon which has some essential spares (Including two motors) for around £15.00.

The drone it self sells for around £40 upwards and the FPV model (First person View) can go for upto £120 as it has the ability to live stream HD video to the remote which it self has a large LCD screen. The standard 3.7 v 380Mah battery pack gives around 8 to 10 minutes flight per charge which takes about 30 minutes via a USB charger, you can also buy a larger 500Mah battery pack to give it a little extra but it is a heavier battery so the difference is marginal at best.
