Knots 2U: Adding Speed and Efficiency to Aircraft

Knots 2U was founded in 1981 for the purpose of adding speed and efficiency to aircraft.

The first airplane modified was a Piper Twin Comanche, which went on to win the Café 400 Air Race in 1982. Soon other planes were added to the list including the Single Comanche, Cherokees, Arrows , Lances, Senecas, Beech Bonanzas and Barons. Knots 2U now has over 70 STC’d modifications with over 60,000 kits installed worldwide! Knots 2U, Ltd. is also a supplier of fiberglass components and lighting to several OEMs.

Unlike some “if it looks good, it must be good” modifications out there today, Knots 2U’s approach has been to use scientific data and analysis to develop the most efficient designs, while at the same time keeping prices reasonable and affordable. Knots 2U also works hard to make sure our modifications are designed with future maintenance in mind. A mod that will have to be removed for maintenance or inspections is made to be removed easily and quickly.

All products are manufactured by specialized contractors, or at Knots 2U’s in-house fabrication and installation shop, under the guidance and constraints of our FAA-PMA (Parts Manufacture Approval). The use of space age materials such as Kevlar and Carbon Fiber are part of the Knots 2U effort to stay abreast of the times.

A trade-mark of a Knots 2U modification is that they are designed to look as if they were meant to be there from the factory and not an afterthought.

We are often asked the difference between our products and others on the market today. The answer is simply look at them on an airplane, you will see the difference!

All of our products are fully STC’d and PMA’d by the FAA. Our kits come with easy to read stepby-step instructions. All necessary hardware is included and the parts have predrilled pilot holes where necessary.

They are designed to be installed easily by the aircraft owner or the local mechanic.

With the recent acquisition of Globe Fiberglass of Lakeland Florida, Knots 2U has moved Globe’s manufacturing to their Burlington Wisconsin facility where production of the Globe Fiberglass parts has resumed. The company now offers an expanded product line of Aerostar, Beechcraft, Cessna, McDonnell Douglass, Piper, and Rockwell Commander parts. Knots 2U, Ltd.
