Hi Brian, Depending on what size airplane your flying it is ok. If its any bigger than a 40 size airplane i would say go with a standard servo but i have used mini servos for throttle before in my 40 size airplanes and smaller. And what kind of push rod are you useing? Sometimes the type of push rod matters if your going with a cable pushrod rather than a 4-40 metal rod.
Hope this helps!
Jon
