I have flown RC helicopters for many years and this is a great plane for the money. We had a perfect quiet evening for a flight, we used 4 batteries and apart from the "Return Home" function everything worked perfectly. We've been in deep space acquiring satellites, I reread the instructions, I had it in headless mode, it just wasn't coming home. Then, in the 5th battery, he ordered him to return home again, he took off and disappeared from sight. Path. I bought this and extra batteries after a lot of research looking for a strong and light weight quadcopter to fly with my grandkids. Headless mode and return home are features I wanted in an ATV to avoid common mistakes when flying with kids. It fit the bill and would have given 5 stars if it hadn't caused the system to crash resulting in a complete catastrophic loss. I didn't have the heart to give it 1 star because everything else about it was great!
