I have 8 on the way for $43 shipped, which I consider an insanely great deal.
I have cheap tri-blades I like because they are quieter. With these very high quality blades it should be really noticeable.
Don't get these if you want extra air time, just isn't going to happen. I have extra batteries for that.
Cool. Keep me posted on if there noticeably quieter that’s all I’m concerned about. Don’t really care about extra flight time just figured that was a gimmick. I’ll probably grab a pair. Not sure how they’ll fit in my back tho.
