All fighters, big jets and many GA aircraft trim by moving the neutral position of the controls. This can be done on the LNC2. The method has been described before and is in the archives. This method does not create weight inside the aileron which then has to be balanced with yet far more weight. The method involves placing a trim servo on the floor under the control stick area. Attach the ends of one bungee cord to the lower end of each control stick. Fasten the center of this bungee to the trim servo with necessary connecting pieces. This system is out of sight, easier to fabricate, eliminates weight inside the aileron which saves still more weight and leaves the aileron pristine. When a heavy wing is trimmed the servo repositions the neutral position of the stick. The bungee also keeps the stick centered while on the ground because it's spring loaded centered. Jerry Grimmonpré
