Yeah...I don't know Aviat wound up in the title. Their bad... I made reference to GM's LS series of engines. I haven't seen one installed inverted like a bf108 yet, but the idea seemed like a good one at the time.That is a Mooney
Donot know what is6 conversions are,but there are lots of Mooney STC mods some of which this airplane has. Wonder why it is labeled Aviat?
