Definitely the most unusual new arrival into our little fleet, the Sova (“owl”) is an intriguing single-seat motor glider, designed and built by Mr. Marijan Ivanček. Among the many interesting details is the propeller – whirled by a two-stroke Rotax – that folds back under the action of a spring when the engine is not running, thus significantly reducing drag during soaring flight without the need to incur the weight penalty of a fully-retractable prop (of note, while the Sova is a glider with an engine, it does not fall into the same category as the Vivat from two photos above. Due to its ability to fly and operate like a “normal aircraft” during powered flight, the L-13SE is classified as a TOURING motor glider; the Sova however lacks that capability, and is thus labelled as an “engine-assisted glider”).
