I believe that you will have a personal issue with the speed of your throttle servo after you get the plane up and flying. The high peformance servos used on the flight surfaces are faster and much more precise. What will happen is that after you get used to the plane and you start into a bunch of 3D stuff you will have problems with the timing between the throttle responses to the maneuvers. A digital or coreless servo would serve your needs much better.
