These guys are gonna need those cells quick.

I don't know if they have flown the E-powered Sonex yet but it seriously needs some better cells to make full scale electric flying more practical. Comparing the quantum leaps in electric flight in RC that I've been active in for 15 years, folks may laugh now at only 1hr flight time but the technology can only improve with time. A 90% efficient motor is just waiting for the cells to make it shine. Plus, we modelers can reap the technological benefits as they trickle down.
