hmm
I was just reading that today. Interesting thought of using the electric to aid in flight.

My thought is I hope the piston/ rod ratio's are decent and allow for a fast break in. some New to gasser guy will stick a ring and we will see a tumbling pheasant hit the ground since Auto rotate wont work and since the electric is on the same shaft.

other than that looks interesting.

I'd like to see one gas engine powering a generator to feed the 4 electric motors. One engine that is temperamental???,,what a drag,,,

Setup is everything, All my heli's can fly far better than I can pilot them

The birth of the hybrid drone. I agree with turboomni. One gasoline engine powering a generator to supply power to electric motors is a simpler and a more reliable setup than having multiple ICEs for propulsion. Think diesel-electric submarine and surface ships.

I can see a time when one or more central gas engines power four variable pitch props. I'm thinking of something like Curtis Youngblood's Sting ray but very much larger.

I can see a smallish gas engine powering a central gearbox and distributing power to 4 or more props. When I say props, I'm envisioning something closer to our current helicopter rotor heads.

The range and endurance would be a quantum bit better. Complexity would be greater but if done well, it could potentially be as reliable.
