On December 30, 2021, Shidi's E20 aircraft made its maiden flight with a 50% scale-down verification aircraft. The E20 aircraft is a 50% scaled demonstration aircraft with a wingspan of 6 metres. The 50% scale-down demonstrator further restores the characteristics of the E20 in terms of aerodynamic shape, adding the configuration of flaps and variable-pitch rotors. The flight test will help correct the analysis results of the aerodynamic simulation, verify the control strategy of the flight control system, optimise the flight quality of the aircraft in the tilting corridor, and further improve our understanding of the prototype and promote the progress of research and development.

TCab Tech was established in May this year. In less than 8 months, we have completed a series of established milestones:

- August, the 25% scale-down verification machine officially rolled off the assembly line and completed its first flight;

- September, communicate with the Civil Aviation Administration on the direction of airworthiness certification;

- October, the 25% scale-down demonstrator has accumulated hundreds of tilting transition flight tests;

- November 13, the eVTOL concept take-off and landing field was released;

- December 1, the full-scale engineering verification machine was released;

- At the end of December, the first flight of the 50% scale-down verification aircraft was completed.

Along the way, we have received help from many friends. Thanks again to friends from all walks of life for their attention and support to us, thanks to Lanchi and Dexun for their trust and affirmation to us, and thanks to all the partners of All Time Technology for their best efforts and enthusiasm. We know that three-dimensional transportation is not an easy road, and we still need to continue to explore and face challenges in the future; at the same time, we also firmly believe that the road under our feet should not be the shackles of our travel, and the sky above will eventually be integrated into everyone's life.
