The body was cut and reshaped so that it could transition into the helicopter structure.
According to Auto Bild's report on the project, Teschke extensively modified the front section and created a new roof area around the characteristic split windshield. Additional windows were incorporated into the upper and front portions of the body, while sheet metal was used to connect the Volkswagen section to the helicopter structure. (AUTO BILD)
The additional windows are one of the details that make the finished project particularly strange.
A traditional Volkswagen T1 has a relatively simple cabin arrangement. A helicopter, by contrast, benefits from extensive visibility because pilots need a clear view of the surrounding environment.
The Frankencopter borrows the visual language of the aircraft.
The result is a vehicle that looks more open and aviation-inspired than an ordinary camper.
The headlights also became part of the transformation.
Instead of simply preserving the original openings, the front area was modified as part of the new design. According to Auto Bild, additional windows were placed where the original headlight areas would normally be, creating an unusual transition between the classic Volkswagen face and the helicopter-like structure.

It is these small details that prevent the creation from looking like two random objects welded together.
The goal was visual integration.
A Helicopter Without a Flight Mission
The most important thing to understand about Frankencopter 4 is that it is not an operational helicopter.
The rotor and helicopter components make it look capable of flight, but the finished project is a static installation.
Carscoops explicitly described the machine as a static installation that does not fly. Auto Zeitung likewise reported that the completed creation would remain grounded rather than becoming a functioning aircraft. (Carscoops)
That distinction matters.
A real helicopter is not simply a body with a rotor attached.
Flight depends on an enormous number of interconnected systems. The aircraft must have an appropriate powerplant, transmission, rotor system, flight controls, structural integrity, fuel system, avionics and numerous safety-critical components.
Every component has to work together within an approved design.
The Airbus H125, for example, is a sophisticated aircraft designed around a specific aerodynamic and mechanical architecture. Airbus lists its Safran Arriel 2D engine, dual-channel FADEC, flight-control systems, avionics and other equipment as part of the aircraft's operational design. (Airbus)
Simply attaching a helicopter rotor assembly to a Volkswagen body would not reproduce that engineering system.
Frankencopter 4 therefore belongs in an entirely different category.
It is an artistic fabrication inspired by aircraft, not a new helicopter model.
Why the H125 Is Such an Interesting Donor
The choice of the H125 is also fitting because of the aircraft's distinctive appearance.
The H125 has a relatively compact cabin, a long tail boom and landing skids that immediately communicate “helicopter” even from a distance.
Those visual characteristics translate well into an art project.
The Volkswagen supplies an instantly recognizable front section.
The helicopter supplies the rear fuselage, skids and aviation components.
Together, they create an object that the human brain can recognize as two things simultaneously.
You see the classic Volkswagen.
Then you see the helicopter.
Then you realize that the two have somehow become one.
That visual contradiction is probably the main reason the project attracts so much attention.
It is not necessarily technically useful.
It is visually unforgettable.
The Engineering Challenge Was Real
Although the finished machine does not fly, the fabrication challenge should not be underestimated.
Working with old automotive sheet metal and aircraft components requires careful cutting, positioning, welding, reinforcement and finishing.
The two machines were never designed to share a common structure.
A Volkswagen body is a road-vehicle structure.
