Years ago when I was in the Army I saw some UAVs (Unmanned Aerial Vehicles) which were powered by Moto guzzi motors. I think they were 750cc but may have been 850cc. The airframes were a little larger than a KR2, because they had to carry quite a bit of heavy avionic equipment, cameras, etc, but then they had engines on both ends. I recall being told that once they were up they could maintain altitude and continue the mission even if they lost an engine. I think they regularly flew missions much longer than the average human bladder can stand. Maybe 8 or more hours. And the maintainers and operators seemed very happy with the performance of the engines at that time.
