Each Pro-Link is machined from titanium bar stock and features a 4-40 right-hand thread on one side and a 4-40 left-hand thread on the other (turnbuckle). A machined hex in the middle allows you to make very fine length adjustments without removing the linkage from the servo arm or control horn. And because they are made of titanium, a 4-inch linkage weighs just 6 grams but has the strength to lift over 500 pounds.
Pro-Links are ideal for Rocket City, DuBro, or any other 4-40 molded ball link or control horn and are available in 1/2-inch increment lengths from 1.5 inches to 5 inches. Hangar 9 also offers a machined-aluminum gold-anodized wrench (HAN3558) that's perfect for making adjustments.
