-ALBI was flying in many modes=There is lots of great info here, especially about the project Malish describes.
I haven't waded through all 68 pages here, but wonder if the Czech UL-39 Albi project has been mentioned. It's a scaled down ducted fan 2-place EU Ultralight category replica of the L-39 Albatross, and first flew in 2016. The prototype is powered by a BMW S 1000RR motorcycle engine, and development is continuing. A detailed 13 page technical article describing the project's current status was published in Journal of Aerospace Engineering 2018, Vol. 232(14) 2721-2733. Sadly, it's behind a SAGE Publications paywall but available for download for US $40.
