Knots 2U

Knots 2U, Ltd. is an aircraft parts and modifications company at 709 Airport Road, Burlington, Wisconsin 53105. It was founded by Jim Bradshaw in 1981 to add speed and efficiency to aircraft; the first aircraft modified was a Piper Twin Comanche, which won the CAFE 400 air race in 1982.

The site says Knots 2U now has over 70 STC'd modifications with more than 40,000 kits installed worldwide, and that it also supplies aircraft parts, pilot supplies, aircraft lighting and maintenance supplies.
