FSX/P3D. Yes indeed many of you know the legendary Milton Shupe and all the many wondrous freeware aircraft he has delivered for us over the years. I was under the impression he had exited development when his addons were archived over at GJ SMITH well as it turns out, Milton and team are very much active and are working on the Grumman Mallard for the past yearn or so and development is actually nearing conclusion. Follow the progress [HERE]
On a separate note, I have just discovered Milton's F7F Tigercat and I must say this thing is kick ass!! I was up till 5am flying this thing and it's absolutely beautiful so if you never flew this bird you can get it via the source link below.
