You’ve finally finished your dream model. The center of gravity is right on, the prop is balanced, and all the controls are hooked up and functioning perfectly. But wait, what about the control throws? Every model airplane KIT and ARF have a specified control surface travel for each control surface. Coming in on a dead-stick, final approach is not the time to find out that you don’t have enough elevator control throw to keep the nose up!

Avoid control problems in the air — check control throws on the ground with the Surface Throw Gauge. Once it’s attached, simply align the “0” mark on the ruler with the edge of the control surface. Deflect it from your radio, and you’ll know in seconds if it’s in “spec” or in need of adjustment. Great for setting up dual rates, too.

● Unique design provides the easiest, most accurate measurements.
● Works with most models, from trainers to jets, with control surfaces up to 5 in. wide.
● Rubber feet grip securely while protecting the airplane's finish.
● Curved ruler matches the controls' motion for precise readings in standard and metric scales (up to 2 in. or 51 mm).
