Tuwood, if we put the servos in the back it would kill our weight and balance because the Saito 125 is a lot lighter than the 120. I was going with the 120 in my Ultimate and an OS 120 in the other one but one the Saito 125 came out I talked my brother into buying one with me. I'm hope to be able to bring the power to weight ratio closer to what it is with the YS 110 or 120 because I know this plane is capable of almost anything with the YS 120 combo. On the next one I might try your carbon rod idea, thanks
