My engine is a bit heavier than yours, but not so much to make this vast difference.

I just finished re-checking the balance after yanking that miserable bellcrank assembly (it was already working loose) and installing two servos just in front of the horizontal stab; the only improvement is, now the battery needs to be just in front of those two elevator servos (instead of on the bottom of the rudder). The three ounces under the stab is still needed.

Tommy, where is your CG at? The more I think about this, the more I wonder if the given CG is incorrect. In 17 years of modeling, over two dozen ARFs assembled and perhaps a dozen kits built, I have NEVER seen one this bad. Three ounces on a 40 size model is one hell of a lot of weight to add.
