Light Delivery Gyroplane (LDG) Development

The latest development is that of the 3-seater LDG (Light Delivery Gyroplane), pictured below, is set to shake the Gyroplane world with its large 37’ rotor and 2.5L Turbo charged Subaru engine with intercooler rated at over 250 hp.

The 3-seater LDG uses most of the existing subsystems of the Kriek and Trojan gyroplanes
