Any idea what the electric equivalent of these engines are? I'd like to build up one of these coroplast combat planes but I'm not a nitro guy so I'd rather use an electric setup. I'm not good enough to fly with the combat guys yet so my buddy and I wanted to build up a couple we could practice with. For us it will be easier to start with electric then when we get better and want to fly combat with the group, then we can build up a nitro plane.
