I spent a little extra money and ordered the MKD lg bellcrank from Central Hobbies and operate both elevator panels from one HiTec Digital. This setup works perfect and has absoluteley no slop. For the pushrods, I built mine from 1/8" carbon fiber rods with 4-40 titanium rod ends. Overkill? Maybe but it sure works great. This a wonderful model to fly. I power mine with an OS 1.08 with a slimline muffler. All up wt is 8.5 pounds.
