Fournier RF5 as UAV
A low-wing stall-prone motoglider, flown without Pitot Tube.
Endurance 30-45min with one battery, but it is so light it would fly easily for well above 1.5h.
Yet, I don't like the fact you have to throw it overhead so it will stay limited.
Cruise speed 45km/h. Shown loiters at low altitude since
at typical cruise altitude of 200m it is almost impossible to track a flying object on a clear sky.
