I converted my Sig LT40 from glow to electric this year. I have an Eflite Power 46 electric motor and a Castle Creations 75 amp ESC. The ESC is overkill as a 60 amp would do fine. I was amazed to fly this plane on electric power. It's about as perfect as I could hope for. This combo has more power than I need, but I also use the plane for float flying. Hope that helps.
