Not stricte gilder but flying tank with motor but I think is intresting. First prototype was build in 1932 in USA by enginier J.W Christie. On plans you can see that should be flying tank with his own propeller and tank engine should drive a propeller when tank flying and tank when wing was relased and tank was on ground. I think that moust be a origin of rusian and japan projects AT-40 and Ku-6 during the war. Some infuences are too in british Hamilcar gilder.
