This thing came out of the box ready to assemble, it was as easy as can be, you can even see how it goes before you make it work for 10 minutes The hardest part is to wait a few hours for a bat. for charging i bought a drone maybe 15 years ago was so disappointed after an hour or so i put it back in the box and gave it to a son friend the instructions for the drone are very easy to start i had them 10 in the runs minutes, it wasn't very good, but I flew it, and I'm 74 years old, and using the phone is even easier. Enjoying it, just wish I had a faster way to charge the battery. I bought 2 extra. but hour 10 min. Just start for me. Come on, JJRC is building us a fast charger
