What Knots 2U does
Knots 2U, Ltd. is a privately held U.S. company, founded in 1981 by Jim Bradshaw and headquartered in Burlington, Wisconsin, that designs, manufactures, and sells FAA-approved aircraft parts, lighting, pilot supplies, and performance modifications for general aviation aircraft. The company's core capability centers on FAA-PMA (Parts Manufacturer Approval) certified parts production and more than 70 FAA-STC (Supplemental Type Certificate) approved aircraft modifications, with proprietary applications of advanced materials including Kevlar and carbon fiber in products such as the K2U Arapaho Wing Tips and Cirrus nose wheel fairings.
The company operates a direct-to-consumer e-commerce business on a BigCommerce storefront, organizing SKUs by aircraft make and model (Piper, Cessna, Beechcraft, Cirrus, Mooney, Van's RV, and others) and by product category (lighting, brake and wheel parts, hardware, maintenance supplies, oils/filters/spark plugs, pilot supplies, and an Aviator Collection of branded merchandise). Unit prices range from roughly $5 for small hardware items to over $1,800 for major components such as nose wheel fairings, with free shipping offered on qualifying items within the 48 contiguous U.S. states. Knots 2U also maintains a network of more than 100 independent FAA-certified installation facilities across the U.S. and internationally (Australia, Canada, Denmark, Germany, Netherlands, Panama, Russia, U.K.) for customers requiring professional installation of STC'd modification kits.
To date, the company reports more than 40,000 modification kits installed worldwide, but does not publicly disclose revenue, employee headcount beyond a stated 11–50 range, or financial performance. The business remains under founder ownership with no institutional funding rounds, no parent company, and no M&A activity disclosed in the available data.
