Well I eyed up the mac 28 and a G23 and a Kalt 22 bare no carb or muff (ok G23). The G23(s) look like a better fit. I was thinking about the Kalt (needs a cylinder) and rotating the cylinder 180deg and running the exhaust out in a scale location. How about your opinions on this one Ralph? What would it take ($) to add an ignition system to the Kalt?
