I hate to suggest it, and maybe I'm wrong, but I wonder if 21C is banking on the brisker sales of the holiday season to release the Avenger and P-51. Seems like we're moving in that direction.
Another consideration is that all the Walmarts around here are still piled high with S1 and S2 FW190's since last November (a bad choice of a plane to sell at Walmart IMO) still at full price. I don't know where they would put the new planes if they received them... lawn and garden?
I know these will be awesome planes, but the wait is sure tough to bare.
