This is a greatplanes C of G balancer for fixed wing models up to 40lbs meaning you can now accurately and easily balance your model according to the manufacturer's recommendations. You can also make precise changes to the C of G location to alter your model's flight characteristics to match your skills and preferences.

The GP C.G. Machine is a tool that improves the way we balance our models. You can now have better control over the placement of the CG and remove some of the worry from those first flights. It's easy to assemble and easy to use. It is a must-have for any workshop or club. Try one and see!

The CG has a profound effect on the way the model flies, handles and responds to control inputs. As most of us know, a nose-heavy model flies poorly; a tail-heavy model flies once. Those who do not know this find out the hard way/
