SIG Surface Indicator Gauge S.I.G. Kit
SIG Surface Indicator Gauge
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. Making sure that your model matches the designer's specifications will turn a twitchy, nerve-racking handful of a model into a pussycat. 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!

The SIG Surface Indicator Gauge enables you to accurately measure and set your control surface throws. It works either in a vertical direction for rudders or in a horizontal direction for elevators, ailerons and flaps.

The control throws are easily measured, without the need of a third Hand, on the laser-inscribed gauge in standard measurements on one side or metric on the other side. Available in two sizes. The smaller size works on control surfaces up to 89 mm (3 1/2 in.) wide which are typically found on planes up to about .60 size. The larger size is for control surfaces measuring up to 152 mm (6 in.), which includes models as large as 1/4 scale.
