I saw it run at Osh. It did sound familiar. Web site says 105 lbs. Also says $2995 for his kit, and the builder needs to add Continental O-200 parts, e.g.: cylinders, valves, accessory case, intake tubes and rubber connectors, bearings, gaskets, gears, lifters, pushrods, oil tank etc. Wonder what the "etc." will cost?
Looks good, though.
