Each Novak Factory-Rebuilt ESC is thoroughly cleaned, passes the same tests as Novak's new product, and includes a new 120-day warranty. Each ESC has a new case and label so it looks brand new. Because it has been previously used, many of our customers think that our rebuilt products are "better than new". Why buy a used ESC from another racer when you can buy this item direct from Novak with a full factory warranty?
