I have always used the cheap futaba 3003's or 3004's on the throttle using nyrod or golden rod for the linkage with ball links on both ends..I have used this setup on many gas planes without any problems and using the nyrod -golden rod keeps any vibration that is caused by the engine reaching the servo..
This is exactly my setup and these maybe cheap servos but they work great and i have never had one fail.
