Your concerns are well founded. Consider, however, if you intend to counterbalance the elevator, you are placing a mere few ounces in the elevator and that very near the pivot point. That should require even less counterweight depending on the arm of the counterweight installed. I think the very short and stiff actuating arm, eliminating possible flutter of the trim tab, is a good trade off. Mine has worked well now for 500 hours of flight time. Go with what makes you comfortable. It's your a## in the seat............\ Larry Flesner
