[Dune 2021] Ornithopter engine?

What type of engine do  Ornithopters use as they appeared to make a whining noise when starting up and what advantages did they have over rotary wing aircraft like helicopters?

They use a type of electric engine. We don't fully understand the technology at play in them but it's far superior to rotary and fixed engine aircraft and combustion engines. The main advantages was having far greater maneuverability and higher top speeds as well as extreme engine efficiency. One could cover hundreds of miles without stopping in a fraction of the time as a modern aircraft and turn almost instantly in any direction. They can also operate at great altitudes that modern aviation wouldn't be able to reach without stalling.
