This VTOL cargo plane is built entirely from parts of the 42025 Technic Cargo Plane. The electric power functions motor operates the propellers, the engine pivoting and the landing gear. The cargo bay can be operated by hand, and is held in place with a swiveling lock. The cockpit can be pivoted by hand, and the windshield can be opened. Rudder and stabilizers can be operated with a mechanical joystick. The current version is LDraw v02 (added 3 missing parts for the cockpit displays).
