i dont understand the point of a a balancer, unless you are balancing a very sensitive airplane and even then.
the majority of the balancing should be happening at the field. set your plane around the manufacture c.g. then go to the field and fly the plane.
pull up at a 45 degree angle and roll inverted. if the plane falls its nose heavy, if it climbs its tail heavy. then add sticky weights at the field till it flies how you like it. when you get back home move components around to counteract for the sticky weights then take em off. i guess you could use a balancer for the measure c.g. then take sticky weights off and move stuff around part, i just use my fingers

what ever floats your boat
