I'm not exactly sure what you mean with your question becuase there are quite a few companies that make 2814 motors, but if you are looking for a quality motor, Avroto makes a very high quality 12 pole 770KV short shaft motor. You can find them at http://hobby-drones.com/opencart/index.php?route=product/product&path=57&product_id=59 Feel free to PM me if you wish to get more information.
