Hensych® 4 Pairs Black Blade Sets A B for YUNEEC Typhoon G Q500 Q500+ Q500 4K RC Air Force Airplane Helicopter Propeller Quadcopter Drone Spare Replace Parts Accessories (Black)

I've given these 2 stars as they are good value compared to the official Yuneec props. But Alas, at least in my case, they were difficult to tighten and the threads didn't fill me with confidence that I wouldn't cross-thread and damage a motor by using them (unlike the OEM props which are an easy fit).So I returned them and won't chance them again, which is a shame as they're a complete bargain compared to the official props

As described, good quality product and I received great service too. The product is a good buy, the price is very good too

The threads on these propellers do not properly match the motor threads, they do not tighten well and sit at irregular heights. When flown, they cause the drone to fly with a lot more vibration which ruins the footage on cameras. I found these to be unusable.

The tread is not the right size. Managed to get 2 blades on with great difficulty and now can't get them off my Q500. I will need to send it into Yuneec and get them to fix it. This is time and money. DO NOT BUY
