On Monday, various thrust tests were carried out with the aircraft secured to the ground, at different engine speeds and with various settings of the new variable-pitch propeller. The results were (very) conclusive: a thrust of around 200 kg was measured.<\/p>\n<p>To the ear, one noticeable difference: the propeller&#8217;s sound is now one or two tones lower than before! But what beautiful solar music it is.<\/p>\n<p>Ground tests, including taxiing, are continuing. We can&#8217;t wait to hear HB-SXA soaring through the skies again.
