In fact the correct way is to use the "balance spring" feature, if you put your mouse over the feature it says it adds a force to counteract grip weight. This is exactly what you need. Moreover it is a very useful feature as you can add force left, right, top, bottom.
The best way to setup it is to launch dcs with the huey for instance, as it has the force trim (if you do not have it you can enable hardware force trim for testing purpose), then you use for trim at different points, top left, top right, and so on, you see where the circle is and where the blue point is, and you add force so the blue point stays in circle.
