Ben doing a lot of reading and looking at the Higley book on weight an balance. And bi planes. Went to Stunt Hanger and their is quite a bit of info on this topic.and it all falls into the infamous pilot point and you get several points of the proper way and it all differs, nothing is the same! Largely depends on the wing area and weight location and length of the lines and diameter of your cables. Some feel you must include the control handle hard point, cable leads, it all reflects. Don’t really understand that. And the placing of weights in different locations, and not adding it at the farthest point. All very confusing but quite possible when considering the folcrum. AJ
