The quadcopter is really semi-professional. Convenient to manage. Trouble-free. For teenagers, it is a good step to learn how to operate a quadcopter before buying a professional one. Almost all the functions declared in the specifications are true except for video and photo resolution. The blade is strong enough, I had 4 collisions, a quadrocopter with a chain-link mesh, a concrete wall, thick grass and a tree trunk. And there was a case when the quadrocopter flew away and lost the signal from the remote control, the return to the take-off point function worked. The quadcopter flew in and landed at the takeoff site without responding to the remote control and manipulations to continue the flight. I recommend.
