Electric vs. combustion !

I can cut the size of a small ac by 7% to the smallest tractor instantly and 15% compared to a complex pusher homebuilt ( BD-5B ). There are two possible locations for the batteries shown. Weight with the tractors remain the same, but a pusher is double the flyweight ( unless electric as well ). I bet there are more weight reduction possibilities just in the pushers...when no rod is needed etc. Plettenberg with 10 kW and 20 kilo batteries and some 4,5 m2 wing area should do it ( with AR 10 ).
