Why should the military have all the fun? The ArduPilot Flight Kit contains just about everything you need to convert an ordinary radio controlled model plane into a UAV (unmanned aerial vehicle) just like on the late night news.
Quite why you’d want to be flying something like this around your neighbourhood is your own business, good luck with the local cops though. Anyhoo, you’ll probably want to take a look at the DIY Drones site as well, while you’re at it. Have fun. £189.99.
This is a kit of some of the main parts that you will need to convert an existing RC aircraft for unmanned / autonomous flight. Please note, this IS NOT a ‘plug and play’ kit. You may need to do soldering, and you probably will have to reprogram the autopilot firmware. Most of the changes needed to make an operational unit are very small, or straightforward to carry out. There is a large amount of support for the Ardupilot system on the internet.
