Mine came in the mail last week; I'm still gathering impressions. Up until today, I was just zooming around, switching back and forth between the A2A versions. This afternoon, I sat down with the manual and started making notes on the Spitfire. I thought I knew this plane, because I had reviewed two previous models and read the test pilot's book. This will teach me to be more humble. I had completely missed some of the animations, including the battery trolley. A lot of research has gone into the different variants -- the Spitfire has four here -- and liveries.
This doesn't answer the questions we normally ask: do these models (1) fly and (2) look better than the existing products? Screenshots (and even better, videos) can help with (2).
