It sure does look like an Echo. Should be a good conversion engine. The Echo/Kioritz are the better quality engines, and are generally light, powerful, and well built. I would convert it myself. It would work fine in an airplane with around 1000 square inches of wing area, weighing from 9 to 11 lbs., or perhaps a touch heavier if it is a floater type plane like a Cub or something instead of an aerobat. You can use it with the original magneto, or convert to electronic ignition for less weight and easier starting.

Hey, you already own it right? A couple of hours work cutting the excess metal off, gut the muffler, buy or make a prop hub, throw on a 15 x 8 APC prop, and see how it does! If you like it, then try a bigger carb as well.

Have fun,
