Hi i have encountered a problem with aileron re-balancing. Apparently, we cant re-balance the cg of the aileron back to the hinge despite adding the maximum amount of ballast permitable at all the balancing stations. What causes this phenomenon? Apparently there isn't any additional weight induce on the aileron due to repair however the cg just seems to shift farther away from the hinge. Also what will happen should the ballast added exceeds the allowable quantity at each individual station. Thanks.
