There are a lot of well proven ultralights out there and some at a very reasonable price. I have owned two ultralights since the early '90's and most people will say they are just for very local and short flights, and for the most part, that's true. But, I just watched a video of the 14 y/o kid that flew his Aerolight 103 758 mi. from Va. to A/V 2019. 32 stops and 7 days. Wow, low and slow ain't all that bad. I have decided to sell the parts that I have built for a CH-701, in 60 days I'll be 73 and I've decided I need to fly instead of build so I'm selling off some stuff to purchase something flying, or, at least close to flying. The desire to fly has been with me since I was a child, I got my PPL in 1974 but I'm still a low time pilot, maybe 200 hrs, and about half of that has been in the last 4 years. Don't give up, you know the thrill of flight, and it will always be with you.
