The original Williams engine design didn't live up to its specs and
they made the decision to change to P&W midstream in the program.
The Pratt's are heaver and have an increased fuel consumption. To get
the guaranteed range, they had to put some more fuel somewhere. They
also had to move the engines forward to get the C of G back to where
it needs to be.

Interesting to see the Eclipse light jet has sprouted tip tanks.

This is new? I thought it was always going to have easily installed/
removed tip tanks. Am I thinking of another light jet? (I thought
it was a cool idea.)
