I don't think you get it. The receiver and handset are happy together; they worked fine in another quad. The receiver and flight control unit *on the quad* are not physically possible to mate up - the wires and headers do not align.
My 9-year-old son and I are undertaking to build a HobbyPower F450 quad. All is well, but we are having a hard time mating our CC3B controller to our Spektrum DX5e receiver (actually an AR610 with a DX5e on the other end).
First thing we need to know: is a CC3B *ever* going to be compatible...
