I'm new to quads, but this is a great value quad. I got the 6S version, never expected to bed to powerful and sensitive to inputs. For learning to hover and basic flying I use 25%-50% throttle with 50% expo, anything above I'm out of control. As it came in the box, I needed to add receiver, and hot glue plastic feet on each arm, because the motors mounting configuration doesn't match the feet. Also the fpv setup was incomplete and I needed to upload frequency table and configure it, otherwise it output only 25mW. Careful gyroscope calibration was also required, out of factory was of. All in all, very satisfied with my new quad. I crashed it many times and nothing happened except for tips of props broke off and grass stuck on the cracks, but still flies with missing prop tips. Super durable!
