    Looking to get into it with some plans, maybe a kit

    I'm young, only 35 years old. Planes have been in the family for decades, handfuls of Ercoups and a beechcraft. I know that I know very little about it all, but I feel the pull toward the sky. I long to soar again like when I was a teenager. Home-building is integral to the history of...

    Experimentals and non-recreational/non-commercial activities

    This question isn't strictly about homebuilts but more broadly about the experimental category and the rules that govern it. I'm an atmospheric scientist, and there is atmospheric research that would be best conducted from an ultralight or at least from a very low-speed, lightweight aircraft...

    Hello! I'm new to HBA!

    Hello! Ever since I was 3 years old, I loved airplanes. I always loved looking up at the sky and watching as airplanes flew by (Yes I am aware of that rhyme;)). In fact, I loved airplanes so much that I was basically the "Plane Guy" of my school. One day we had to choose a topic for a class...

    ultralight design for high altitude runway (airfoil, aspect ratio, loading, dihedral)

    Beginning a design of an ultralight (US 103) to fly from a base near 5400 feet (1640 m). Yesterday we had gusts to 39 mph (63 kph) with airs temps to 85 F (30 C) in clear air and no clouds within 10 miles. Take off in those gusts would be foolish, but they came up very suddenly out of a blue...

    Legal Part 103 single-seat trike as flying boat (like Polaris or Sea Trike)?

    I am searching for an inexpensive low-n-slow Part 103 one-seater Trike with floats--no x-country, usage in favorable wind conditions only. Looking at the non-103 two-seater "flying boats" from Polaris and Sea Trike from the '80s and '90s gave me a crazy idea... why not use an inflatable boat...
