The Foil Drive Gen2 Stator, is just one component of the Gen2 Motor, you will need to use your existing Props and Rotor. 

This Stator is compatible with both the Foil Drive Assist MAX and Assist Slim, and is available in a variety of cable lengths for adjusting motor placement on the mast.

The motor mounting position is a personal rider preference and can differ between disciplines of foiling. Foil Drive motors should be considered like a quiver allowing you to customise or fine tune your set up to how you want to ride.

This only includes a Gen2 Stator.
