You should go over to wattflyer and ask, bottom of the header bar. It's a great plane to build and a super plane to fly. Electric power?? This year I built one and used the OS .91 FS in it. Way more power then needed, a two stroke .46 would do just fine so that may give you a clue for electric power but there should be a gang of people that are flying it over at wattflyer to give you a hand.
