At 100% scale the GL-10 will be power lithium-ion batteries with a pair of 8 hp diesel engines which will drive 10 electric engines—eight on the wing and two on the stabilizer. The tilting nature of the wing and stabilizer gives the capability of not needing either a launch system or a large operation space. Currently, the Greased Lightning has been flown at 50% scale in vertical flight. Low propeller tip speed lends a quite nature to the GL-10 but its chief characteristic is its high cool factor.

    It manages to be both cool and ugly at the same time. Quite a trick. Video is flight test from takeoff to transition.
