Pros It was incredible, scary fast, had good flight times with 6 inch props, could easily switch between horizon and full acro, had a beep to find it , if you land somewhere where you can't see it. Initially, the OSD showed DC voltage. Transmitter, so the rotors don't shut down if he loses connection, for example. It had good range compared to my Bugs 3, but after a few falls it kept losing signal, then fell out of the sky. , smashed the 4S battery, broke the standoffs on the power supply board, and smashed my Yi 4k camera. I followed the instructions to set up the transmitter properly, but everything is still the same. It's not easy to read the station's screen in daylight and I found it beeping and saying something like "Low RSSi". Even when using different batteries that are fully charged. It came with ONE set of drone props worth over $300. It should be RTF and it is, but it's extremely unfriendly in terms of customization options. I spent hours tweaking the settings. Connection not possible. Very frustrating. I've flown my Bugs 3 drone for many hours so I'm not exactly a noob. But I couldn't adjust the settings to reflect the voltage reading on the OSD, which I could totally live with, but I really couldn't get my range back, kept getting "low RSSI" even when I was maybe VERY close to 10 up to 20 meters? I REALLY wanted to leave this thing. *** UPDATE I returned it, got an Arris 250B with a Taranis transmitter back in the summer of 2017, but it had TERRIBLE range. It would randomly lose connection, sometimes reconnect, and sometimes just fall and break like a brick. Even if I was maybe 30 meters away with no trees or anything. In the same places my friend flew hundreds of meters with excellent reception. I put the antennas up in the air as EVERYONE did but he kept losing signal. I didn't trust it, it crashed again, I spent HOURS on tech support last summer, it was SUPER annoying. It hasn't flown since, now it's just bad details.
