I was at Wal-Mart today and they had 1/18 scale Stukas and FW-190-D's for sale. They are nice looking aircraft but you have to paint your own swaztica on the tail. They are sold by Wal Mart under the Motor Work lable, but 21st Century Tools makes them. I have the winter Me-109, British P-40,and P-51. All have working canopys,landing gear, props that spin and some have flaps that work. Very nice for $40 and well painted and decaled. They also make big tanks too.
