Right now, as pictured here, with the steel muffler and kill switch it weighs 3lb. 11 oz. I've still got some more work to do on it though. Going to make a G-10 carb rotator block, will either make or fit (if I can find something around here that fits) a lightweight aluminum muffler. If the weather is lousy this weekend I might even mill some grooves in the prop hub to lighten it a little. Got to give it a chance to run on equal terms with all the other weedies.
