Don,

Yes, that servo made me nervous. I have since replaced it with a Hitec high torch metal geared servo which I mounted in the rear of the tail as shown in previous posts. As far as strong and fast servo's, the throw required is only 3/8 on low and 5/8 on high. I have never even tried my high rate. Even on low I have plenty of authority, even when slow. I used the inermost hole on the sero and the outermost hole on the elevator arm to get the best mechanical advantage I could.
