Douglas "Duck" Danaka is the Crew Chief of Team Fastex. The job of the Crew Chief is to gather information about the driver, the car and the track and come up with connections between all three. In the show, Duck just seemd more like a general mechanic than a Crew Chief. We later find out in the show that Duck used to race in NASCAR along side certain Nascar Legends such as Ferrell Long Street and Junior McCutchen, but soon gave up and become a Crew Chief. Throughtout the show, we learn that Danaka has a long history with both Jack Fassler and his wife Libby. Douglas is usually assisted in the garage by Meagn Fassler as well as Miles McCutchen. Later on, a General Mechanic named Lugnut Gooch is hired to help him in the garage
