As far as weight goes.. it's too bad the weight limit isn't setup for a fueled aircraft at maybe 12 pounds. The electric clearly has the advantage here as there is no weight change through the flight, no lean runs, blown plugs, etc.

I believe YS and OS should be very nervous by these developments. When an electric system comes in UNDER the price of a YS 1.60DZ, lookout. It's not too far off I think.
