If you are going with GWS check out there park flyer radio its only for park flyers but it is cheap. The best way to get the servos is to buy the GWS Flight pak for the Slow Stick. You will get everthing you need except the crystal. Make sure you know what radio you are getting before ordering since you need to get the right shift rx (pos JR/Airtronics, Neg Futaba/Hitec)
