Watch out, Futaba owners. Just bought FSone yesterday, I am installing it tonight (its now 9:36 pm) the box clearly states adaptors for JR, HiTec/Futaba. I have three Futabas CAP9, CAP7, and buddy box All have the rectangular plug. You don"t get an adaptor for the rectangular Futaba plug. They are more than happy to sell you one for $13 + ship and handling. Sorry guys I didn't realize HiTec/Futaba meant HiTec and some other Futaba than the ones I have. I know I'm supposed to be real sweet and nice and tell everyone how wonderful the world is, but this is frustrating, and its the truth. I will have to take time from work tomorrow to call and see what my options are. I will probably spend more money and get their TacCon controller, I know Horizon is the JR distributor and doubt if they have much interest in connecting to Futaba. Sorry guys I know Horizon and Hanger 9, have or had many of there great airplanes P-51, AT-6, funtana X 100, etc, and other products ie, Saito engines. They just upset me with this.
