The U843 Sky Walker is a versatile quadcopter that can be built into 4 different configurations. Firstly there is a ‘minimal’ setup with no accessories, this gives you the optimum flying performance and least weight. Then you can add the guards to that for added protection as you get used to it or for flying indoors. Then there is a ‘car’ setup, this has 4 wheels and allows you to drive the quadcopter along the floor. Finally, there is ‘big wheel’ mode designed to enable you to climb walls or run along the roof and give the most protection.
The micro electronics inside the U843 are exactly the high quality that you would expect from UDI. With 6-axis gyro stabilization and selectable skill levels (novice & advance) it makes a great introduction to multirotor flight for the novice and in advanced mode you can really challenge yourself around the house!
