The UDI RC U839 quadcopter can fly both indoor and outdoor with ease and is a great nano drone to own. At just 3.5" and 36g it has 7mm coreless motors and a 6-axis system that allows it to be hand launched. Its 6-Axis gyro quad-rotorcraft flight also helps it easily implement various flight movements.

It features a 4-channel 2.4 GHz technology for its controller that helps in anti-interference, so even if more than one quadcopter is flying at the same time they will not interfere with each other. It can also control the quadcopter till a distance to about 30 meters.

The quadcopter has strong wind resistance, great stability and is easier to control than most mini sized aircraft due to its small volume and the lightweight. It can even perform flips and 360 degree rolls in any direction and you can start its high-speed mode for outdoor racing.

Its modular design is built from impact resistant ABS plastic and it has 4 safety-protected propellers as well. The 4 highlight colorful LED lights help the flyer indicate the direction in the night and it also increases the visual perception of flight.

It uses a Li-Po 3.7V 150mAh battery that takes around 40 minutes to charge via a USB cable and the battery lasts approximately 5-7 minutes when flying on a full charge.
