Here is my homemade balancer with measurement arms. For this plane my target balance point is 3.25". I set the arms at 3.25", set the plane in position and then move the arms out 1/8" so the plane is not touching the arms. In this case the plane was nose heavy. See weight on horizontal stabilizer. I moved the wing forward to balance. Now it is slightly nose heavy. Will check it again before first flight.
