I can hardly tell you how many times I have been asked if there is a decent 4stroke engine for very light aircraft, including Part 103 ultralight vehicles. Too often the answer has been, "I knew of one, but they seem to have left the business." While we have other choices coming, one that has been proven since Sun 'n Fun 2022, is already available, and is working beautifully is the Aero 1000. This engine is manufactured in Switzerland, using the same quality their famous watches receive, but it is now represented in America by AirTech, Inc., the world's leading expert on Quicksilver aircraft and many other ultralight vehicles.
