I am new to flying non toy grade craft. I bought a FT Seaduck and am looking for a radio that will work for it properly. I want to keep it kind of cheap (less than 100). I am looking at the Turnigy 9x or the Spektrum DXe. The reviews for them seem all over the place but they seem to have the mixing capability needed for differential thrust. The ability to bind and fly RTF planes would be cool but the idea of building the FT planes seems more enjoyable to me.
