Trying some more 4s on this 3 inches of love. 450mah Tattu 4s. Again I don't have osd on this set up. So can't see any sag, but definitely didn't feel it until the end of a speed pass. I'd say these are a bit better than the Graphenes 500 4s. 15g lighter. Same flight times and a bit more punch as you can see compared to my last video.
My own frame design.
