2017.07.02  Hello Paul,  I've found some infos about a rearly good looking plane. Propeller
is driven by an electric machine, power comes from a RE RE ;-) (Rotary Engine
Range Extender) placed behind the seats - good weight distribution ...  It's just fun to look at the design ... ;-)   With kindest regards  Franky / Frank Herfert


It is so stupid having an engine driving a generator and then
driving an electric  motor.  This is indicative of their defective technical education. The laws of physics are not just a good idea. They are the LAW!  When you multiply the efficiencies you wind up less than 20% over all fuel efficiency.  Technical education is being corrupted by

Whacko environmental stupidity.

One advantage might be that you could get rid of the planetary gear drive train if a variable frequency motor drive is used.

Why would you want to do that? The planetary is the best
gear box and it has been used on aircraft engines for the last
100 years or more. Up to 99% efficient.

There is no better way of doing it.

You need to do a little reading about air craft engines.
