Last year we introduced the Yokosuka D4Y "Suisei" (Judy) of the Planes-of-Fame-Air-Museum; HERE.
Today our friend Devlin sent us a heads-up for the following video on YouTube, here.
The text explains:
"The Planes of Fame Museum Chino's recently restored Yokosuka D4Y Suisei ("Comet" - Allied code name "Judy") performs its first engine test as part of the museum's Living History Flying Day Event, "Japanese Combat Aircraft," on 1 December 2012. Unfortunately it's not an original engine; it's off a DC-3."
