This is a smart drone which uses various sensors to find it’s way around. While most quadcopters allow you to fly them into walls and windows, this platform features sensors for avoiding obstacles

Last year we reviewed a fine quadcopter from Walkera, the medium sized MX400

In the time since, Walkera has come out with a number of additional multicopters, including the well regarded and tiny Ladybird. An advanced version of this fine bird is now available which have some amazing technology built into it! This platform features sensors for avoiding obstacles.

Here is a hands-on review of the QR from RCproreviews.
