After more than four months of intensive testing, TCab Technology's E20 eVTOL airframe has successfully completed all tests from system joint debugging to test flight. At more than two tons, it has been designed with the same take off weight, power arrangement and system equipment as the full-scale prototype, and test results have established a good foundation for the next stage safe flight test of the prototype.

The team has successively experienced multiple test stages of system joint debugging, ballast durability, tethered and untethered flight, and accumulated more than 320 take offs and landings. Thanks to rigorous and meticulous work during the design, manufacturing and equipment-level tests and the active cooperation of suppliers, performance was stable and reliable during the system and complete machine tests. Work can now concentrate on the analysis of test data, improvement of the simulation model, tuning of the power unit and control law parameters.

The airframe is an important platform for power system verification, and flight control and avionics joint debugging verification. The tests speed up the resolution of technical problems, effectively reducing risk during the prototype flight test and promoting the smooth progress of TCab's E20 eVTOL project. Since then, the project has entered the complete machine testing and verification stage, and the E20 eVTOL prototype has entered a comprehensive flight test.
