Ladies, ladies, please. An end to "

The range extender replaces the ability to use the rear seats. (Kind of sits on top if the space).
You could get more range also by fitting an EGT lean-o-meter and lean to max plus fly higher. So you can get more than 3hrs from a standard R44 without the extra drop tanks (but the PoH does not recommend leaning) - see sep thread on this somewhere here.
