Russian engineers have invented a bunch of genius devices over the past few years. And now, they've created what's believed to be one of the smallest and lightest helicopters in the world.
The invention weighs only 115 kilograms and can reach speeds of up to 120 kilometers per hour. The chopper can easily take off from any landing site with a 10 meter diameter.
What's more, it can be easily folded and unfolded within minutes. And thanks to its unique compact size, it can be transported even in a car trunk or on a small auto trailer. Plus, the copter doesn't require any license or registration.
