On this Eclipse, I have moved the wing tube back 1/2" to achieve proper balance when using individual elevator servos. On my first Eclipse with the pull-pull cable on elevator and the wing tube at the standard location, I came in very tail heavy. I had to put the battery on the fire wall and still had to add 3oz of lead in the nose. Moving the wing tube 3/8" would have solved my problems. My 1/2" move allows for the extra weight of individual elevator servos. I do keep the weight down by using the BPG CF wing tube and the bolly FAI landing gear. These two changes saves 4 to 5 oz in weight. All in all, I project the weight of the plane to come in between 10# - 0oz and 10# - 2oz.
