RE: DA50 Balance in Edge - pull pull elevator?
If you want to make the balancing really easy without going to extremes, use a CF stab tube. I got one at .5 inch diameter and 22 inches long to $ 17 bucks. Worked like a charm and I am using a DA50. also, allowed me to use CF landing gear, tail wheel, without having to move everything to correct for the weight of the engine.
