I installed them on my phantom 3 pro. I took off and went maybe 50' up hoverd for a minute I didn't like the way it was handling and started to land. Then I got a warning that I lost GPS signal and upon landing she bounced a couple times and flipped over. So I'm just throwing a caution about using those propellers. I'm not saying that was the cause. But I never had a warning on looseing my GPS signal while owning my p3.
