You can go expensive or cheap. Offshore electrics offers sharpening and balancing. They are usually backordered but you can get a carbon fiber prop set with shaft conversion all set for the Vill. You can also order copper berylliums from octura. I think the part numbers are x447 and x447r. If you replace the props with non traxxas props you will need a shaft conversion set. You can get the stock props from Tower for real cheap. I bought a couple sets of these just as backups for my good props.
