I have mixed feelings, the drone comes pretty well tuned. the construction is robust enough to take some pretty good hits, I did install the carbon fiber support "X" to help. it will fly with an 850 battery bit motors don't love it and props are too small for that weight 450 is ideal. the one big issue is the motor wires are not well protected in only a few flights you will end up cutting them with your props , and that means soldering new wires to the old and re-attaching to the board. I highly recommend taping them in place if you don't like needless work.. but I didn't know. If the fix the wore routing or secure them better this would be a 5 star review.
The quad looks amazing. It’s nice and small and the quality seems next to none! It includes all different sizes of screws and to my surprise a carbon fibre support brace that can be added underneath the quad to increase the strength of the frame. Haven’t flown it yet, due to bad weather, but look forward to it as soon as the weather lets up.
