I use the HobbyKing Orange Receivers in several of my Planes without any problems and for a fraction of the price of the Futaba Receivers; if you are reluctant to use anything but Futaba be prepared to pay the money, you may find them cheaper on Ebay; what I have done, I use the expensive Futaba Receivers on my more expensive Planes and the HobbyKing receivers on my less expensive and Combat Planes.
