Quadcopters are the most popular of Remote Controlled Aircraft and I don’t have many in my collection so I bought one from Amazon called the Holy Stone X400 for 109.99. This video I review its pros and cons as well as what’s included in the box. I fly the Quadcopter indoors at night and then outside in breezy weather. It is a Wifi FPV Quad with a small camera you connect to your phone to stream and capture footage from the air. It does fly very well but the camera quality isn’t all that great it’s still fun to fly. The Application to use for video on this quad is MJX 4005 FPV. Enjoy this long video review.
