SIG Pro-Balancer

Out of balance?

Center of gravity is no small thing. Just a fraction of an inch change in balance point can make the difference between a solid performer and an airplane you have to fight just to get back down in one piece. Differences in engine and radio selection, along with other factors will alter balance.

With the SIG PRO-BALANCER, you can quickly balance your model and propellers from one simple device. The Pro-Balancer will handle nearly every model in your fleet (fuselage widths up to 11 in (28 cm) and any size model propeller. Made of carbon steel & laser cut SIG plywood it's equipped with ball bearings to last for years.

 Center of Gravity Machine

The center of gravity (CG) for any model has a profound effect on the way it flies, handles, and responds to control inputs. As most of us know, a nose-heavy model flies poorly; a tail-heavy model flies once. Fliers who don't know this will find out the hard way!

Now you can accurately and easily balance your model according to the manufacturer's recommendations. You can also make precise changes to the CG location to alter your model's flight characteristics to match your skills and preferences. 

In the excitement of flying the latest masterpiece that you've labored perhaps months over, do you take proper steps to determine its CG?   Maybe you do a quick check of the CG using our fingertips. If the plane is too large to do this by yourself, you have your wife, girlfriend, flying buddy, or one of your kids help with the task. Such results are often less than perfect.  Don7#39t risk your masterpiece!

Dead Center Locator Tool

Marking the drilling hole pattern in an engine mount is an important task.  When improperly drilled, the holes can over-stress the mount, cause the mounting bolts to bind as they are attaching the engine to the mount, or even worse, allow for destructive vibration. But with the Dead Center Locator, you can quickly, easily and accurately pinpoint the exact spots where the hole should be.  And it's so affordable! Dead Center in-use photo Dead Center lineart
