A good thought Speedracer and something I had considered doing as well. Thing is, with the ball links centered between two thinner servo arms the crossed rudder cables would rub each other. I have seen where others have mounted one ball link to the top of the servo arm and the other to the bottom to alleviate rubbing. Not sure I like that idea but it is a dual bearing Ti geared heavy duty servo. May be ok on a 25% Yak.
