hybrid drone generator FD16K generator is a high efficiency generator designed for multicopters. FD16K generator is only 29.5kgs
For my single seater i would have enough cruise power with 28kw maybe. So thats double than the attached generator or 60kg. Wonder how much battery weight i would need to overcome takeoff phase until recharging kicks in again.
Such a generator engine can be located everywhere in the plane and would be atractive for unconventional configurations with CG difficulties.
i like the idea if improved a bit
