Hangar 9 Titanium Pro-Links 4-40x1-1/2" (2)

With their size and weight, giant-scale aircraft place greater demands on their control systems. This is particularly real for giant-scale aerobatic aircrafts. Hangar 9's Titanium Pro-Links offer the supreme in strength and security with the added benefit of ease of adjustability and ultra-light weight.

Each Pro-Link is machined from titanium bar stock and includes 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 center enables you to make really fine length adjustments without eliminating the linkage from the servo arm or control horn. And because they are made of titanium, a 4-inch linkage weighs simply 6 grams but has the strength to raise over 500 pounds.

Pro-Links are perfect for Rocket City, DuBro®, or 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 likewise uses a machined-aluminum gold-anodized wrench that's perfect for making adjustments.

Hangar 9's gold-anodized machined-aluminum arms have actually been popular for years. They offer increased strength and rigidity, plus they actually look cool! Previously the longest arms available were only approximately 1" in length. Many 3D and aerobatic pilots simply couldn't get enough control surface toss, particularly on rudder for 3D aerobatics. Now Hangar 9 is offering a 1.25 in long 3D Machined-Aluminum Servo Arm. The arm is tapped with 4-40 threads and accepts most 4-40 ball links (Rocket City, DuBro®, etc.) and is available for JR/Airtronics or Futaba servos. Now 50° + tosses are possible so pilots can 3D their brains out with total control linkage security and look excellent while doing it.
