The way to check the CG on any flybar equipped helicopter is to first align the blades with the tailboom... Using a finger from each hand, cradle the flybar near the head (the flybar should be perpendicular to the main frames) and gently lift... Pay attention to the skids as they leave the ground... If the skids leave the ground evenly or the front SLIGHTLY LAST, you are good to go...

Keep in mind that the heli should be in the configuration that you are going to fly it when you do this little test i.e. canopy on and fuel in tank... It is much easier to fly a slightly nose heavy heli than a tail heavy one...
