Just on of loud thinking scenarios.

Lithium batteries are cheap to obtain, thanks to Tesla cars being sold and crashed all other the world. So - something like 800-1000 usd per module with 5.6 kw/h capacity and 25 kg of weight (with bms and contractor if i am correct + structure) on module is capable of 30 kw power.

Motors like emrax 188/208 8-9.5 kg with 30-40 kw peak power at 3500 rpm, or 16-20 kw at 2000-2200 rpm.

Controller for this configuration 4-6 kg ?

So in total - 1.5 or 2 modules, + motor/controller will weight 52 kg / 65 kg for 1.5 or 2 packs. And could provide 30-40 minutes of cruise power comparable as rotax 447/503 engines. And with close or same weight as 447/503 with 5 gal of fuel.

+ less weight for prerotator, you have already a lot of batteries.

+ you could build it as tractor in same configuration as JT-11 - propeller/motor - pilot - mast - batteries.
