Readers of the mags edited by Brett are probably familiar with the name Kamil Feliks Sztarbala. Aside of writing articles on building and finishing aircraft, AFVs and military vignettes, Kamil also sculpts figures and releases these under his KFS-miniatures label. His latest creation is 1:35 scale U.S. Goliath Rider, intended for recent Tamiya kit. This set contains a figure inspired by a famous photo, Goliath upper hull part modified to allow trouble-free installation of the figure, and of course the remote control for the rider, which is cast together with the hands.

That looks really good - I had thought of doing that very thing!
One thing you might let the owner of KFS know, though, is that the sight asks a viewer to click on something that only a Polish speaker can read before entering. Every net security training I have ever taken says not to do that. More language options might equal more sales.
