HP Aircraft is a composite aircraft development firm located in Arnold, California in the foothills of the Sierra Nevada mountains. We specialize in carbon fiber aircraft parts and kits for amateur-built aircraft, but our products also include parts for racing aircraft.
We also conduct regular “akaflieg” sessions, where people from all over the world get hands-on experience fabricating composite aircraft parts from carbon, Kevlar, and fiberglass materials.
We also have a Facebook page for HP Aircraft, and a Facebook page for the HP-24 kit sailplane. There’s also an old-school site for the HP-24 that I hand-coded in HTML back in the day. We don’t maintain it anymore, but it is still a valuable reference for the Resourceful Builder.
