Mootorlennukid
Mootorlennukid refers to motor gliders, which are aircraft that combine the capabilities of gliders with those of powered aircraft. They are designed to be able to soar like a glider, using rising air currents to gain altitude and extend their flight time, but also possess an engine that allows them to self-launch, extend their range, or regain altitude if air currents are not favorable.
The engine in a mootorlennuk can be either a retractable motor that is stowed during gliding flight
