I've tried electrics several times, and have always gone back to glow. The things I didn't like about electrics were 1) the loss of power as the flight progressed, and 2) the necessity to shave grams off the airframe wherever you can, just so you can drop in a heavy battery. I built a GP RV-40 park flyer a few months ago, another go at electrics, and never got past framing it up. It seems so flimsy with its 1/32" sheeting and 1/16" stringers. And you can't even cover it with Monokote--too heavy. I may yet finish it and fly it, but it'll never replace my glow planes.
