As part of an exhaustive continuing test program for the H3 Easyflyer, a machine was recently sent to the United Arab Emirates for testing in temperatures of 42°C (108°F.)

The test flights validated calculations made at the Dynali plant and demonstrated that the H3 could operate throughout its flight envelope at such temperatures with a takeoff weight of 500 kg.

The only modification made to the standard H3 was the installation of slightly more powerful cooling fans which maintained coolant temperatures below 85°C throughout the flight program, which included long periods of hovering and maximum power climb.
