I found another reason to like electric. With IC, there's only so much you can do to lighten the nose if a plane is nose heavy. Lighter spinner, maybe go to a plastic tank, but that's near the end. My new plane was nose heavy. I built a new battery carriage (lost 3/4oz - OK, the old one was overbuilt) and went to a lighter battery (a 25C versus a 35C battery) and lost 1.75 ounces. so, I've lost 2.5oz from the nose. That should do it.
