Meet the Microturismo: one of the smallest RC formula cars around with a camera that lets you view all the action. It comes with everything you need to race against up to 8 players. It has a 5.8GHz RF emitter for video and driving, so you can race and view all the action on your phone. The car runs for up to 40 minutes on battery. The chassis is adjustable too.
The developers are making all their 3D part designs available, so you can 3D print replacement parts and upgrade your racing car. Like what you see? You can find this project on Kickstarter.
