It's not that I need them cause I'm always tipping over, it's more like They're cool looking and something I can put on to make my Phantom look different, I don't like the skins people are using on their Phantoms, so there really aren't a lot of ways to outfit them that look good to me. I think DJI needs to make some different looking models for example instead of the rounded arms, I think triangle shaped arms would look good and more streamlined.
