Siemens SP260D

Post by 282ex » Fri Jun 14, 2019 10:19 am

The dawn of electric propulsion is upon us. There will be a tipping point when the storage hits 500Wh/kg (presently around 300-350Wh/kg). All the major aircraft companies and even airlines are investing in research.

Ths SP260D is about 350hp, SP200D is about 250hp. I think that once I can stuff enough batteries into the fuse and wings, and the motors are reasonably price, and get 3.5-4 hours of flight, I might be up for a conversion.

Thoughts welcomed.

The motor tech seems to be there. Now we have to wait for the batteries to catch up. Just from a reliability perspective, I'm all ears. Electric propulsion looks promising and I think experimental category aircraft will lead the way.
