This is a 3D printed replacement for the rotor head / blades grip of the Durafly / Hobbyking Autogyro G2V1 and G2V2.
Perfectly compatible with the original blades, shaft, etc. All the nuts and bolts needed are included, it's coming ready to mount your blades.
If you choose to mount thicker blades than the original ones, you will need 6x longer M2 bolts.
Please note that this is a 3D printed product and might have small surface imperfections. However, it will work at least as good as the OEM one.
