Thought I would give these a try...not good. When I received them ALL the props were out of balance to the point to where I almost couldn't balance them. Finally got them acceptable and put them on the bird. They seemed to work okay with no wind but, when it got a little windy..you can't stabilize the bird. Also, I lost almost 5 minutes off the flight time because the pitch is way too drastic for the quad. 5" pitch to where the stock are 3". They also cause a tad bit vibration in video. It definitely made the quad more snappy and faster but overall..the props are very dangerous and I would not recommend these for your Q500+. I am sending them back for a refund.
