One of my main issues with the 550L when I was researching it in October 2014 was I couldn’t find many photos of the helicopter against reference objects. Size isn’t everything, of course, but as I said before I was suprised how big it feels compared with the 450.
Here are some more photos of the 450 Plus DFC against the 550L.
Front view gives a good idea of the scale.
