T-Trees 4PCS High Landing Gear Skid for DJI F450 F550 SK480 Qudcopter Multirotor Black

These look great and are a little longer than the ones that came with my DJI F550. The screw holes were a little of but not enough to make mounting them a challenge. I can't say what reliability is like on a hard crash because I just put them on today. The plastic seems to be the same quality as the DJI landing gear and it also had about the same amount of flex.

Works great.
