HQProp 5X4X6 Light Grey (2CW+2CCW)-Poly Carbonate

Super fun

Gives the quad really fast acceleration and super tight cornering abilities but introduces a ton of prop-wash. Really fun set of props overall

Worth a try

I got these for a 5" freestyle quad to see if they really were quieter than the normal tri blades. While they are quieter they also shake and cause incredibly amounts of prop wash. I made the mistake of using these when filming a video for Instagram and gyroflow could barely fix the shaky footage. They are worth a try and fun to experiment with but seem to need a full re-tune to prob fly smoothly.

works great
