Sky buggy

The concept of a flying car is really cool and I wanted to design an actual flying car. Of the realized projects I've seen on the internet, I concluded that four-wheeled cars can already fly, but they bear little resemblance to cars in our usual perception. All of them are compromises. They resemble carts for transporting folded wings. Calling them real cars is difficult. In my design, I completely refused from wings. My concept was lightness and minimalism. How great it would be to fly up to mountains where there are no roads, and race a sky buggy. The total weight is 350 kilograms, of which 150 is the pilot and fuel. To save weight, I refused from a mechanical transmission of strength from the engine. The turbofan engine is directly connected to the generator via a reducer. The electricity is distributed by a computer between the electric motors. So, the sky buggy is fully electric. In car mode, it is moved by two electric motors on the rear wheels, which also act as electric brakes. In helicopter mode, it uses three engines: two lifting and one tail. All rotors have variable pitch like in helicopters. Additionally, the computer corrects the overall position of all rotors. A very important point is the center of gravity. In car mode, the weight is distributed: 40% on the front axle, 60% on the rear. This distribution of weight improves off-road capabilities of the sky buggy. In helicopter mode, the center of gravity is completely on the axis of the lifting rotors. For this, I placed all components appropriately. For example, a large fuel tank is located right under the axis of the lifting rotors, and the fuel consumption does not affect the center of gravity. The tail extendable beam also works on centering. Depending on the weight of the pilot, it extends to different distances and acts as a balancer. The lifting rotors in the folded position carry their weight onto the center. To lighten the sky buggy, I had to give up many things. You won't even see any control devices. All information is received by the pilot in his helmet. On the helmet glass, a computer displays all the necessary information. All controls are handled through the steering wheel. It's a shame, the computer itself is behind the pilot's seat. The pilot's seat is also lightweight:). Wide wheels look impressive but weigh a lot. I refused wide wheels, as well as many other things. In general, the sky buggy is very little aluminum, carbon, and titanium! If it doesn't fly, it won't be light! But some things can't be done without, so I installed an aviation radar in the nose part. Among the minuses of such a concept: high engine noise, relatively high fuel consumption. Among the pluses: it drives, flies, and can perform vertical takeoff! I wrote that I connected to the challenge very late. A lot of things just didn't happen and some things weren't polished. I hope you can understand the design concept from what I managed to do. The external forms are from functionality. In any case, I am very grateful to GrabCAD for such an interesting topic that briefly distracted me and gave me a chance to relax from the situation in my country. P.S. Renders... how slow they are made... So I'm sorry, I can only upload screenshots of SolidWorks.
