We are still in the phase of flight testing. The pictures above show test flights where we have to determine cruise speed and fuel consumption. So far these values are in the expected range, e.g. 92 kts TAS in 4000 ft.
But the tests in hot weather conditions also showed that the engine temperature is a little bit high. As a next step we need to improve cooling. So the next weeks we will work on optimizing the airflow into and out of the cowling.
