You'll have to do somechecking because that EBay page gives no real information about the connections etc. Are you planning to run the receiver on 12V? If so you'll need a simple 2 resistor voltage divider to connect the switched output to an Arduino pin which can only take 5V.
But other than that there should be no problem. I would first write some code which moves the servo when a switch is pressed (there are several examples in the IDE showing how to connect a switch and how to drive a servo). When that is moving the servo as you want just change the switch for the output from the receiver. Job done.
