I decided to replace the elevator servo with a HXT900 servo as I wasn't sure how long the supplied servos would last. So I cut it out and replaced it. No issues and I could check the servo arm (which are cheap!). The servos are glued in place and don't present a problem cutting them out. I don't tend to fly with the rudder servo so I have left it in place. I find you don't need rudder to do (sort of) good turns with the model.
