i recently bought the phantom 3 advanced. There were 4 pair props with it, originally dji!!! They had a plastic inside the screw contact position. The props feel a little bit sharp on the edges and not so good quality. Before i flew the phantom 2 vs 3.0 props with the metal screw contact position inside. The edges feels smoother and the quality of the props looks much much better! And they were silent! Question 1: is it an idea to use the phantom 2 props? If incan find them beacause i sold mine... Question 2: are the originally phantom 3 dji props really sharper on the edges? And not so good quality? Question 3: what are the most silent props of the best quality? What props are you flying? How can i recognize them?
