I brought the ailerons out the the airport to weigh out the counter balance weight. I installed all four and leveled the aircraft poured the counter balance weight into the cup and hung it from the leading edge. I found that the lower ailerons need about 0.75 lb of leading edge weight and the upper ailerons need about 0.8 lb with the slave strut installed.
