DX5e DSMX 5-Channel Transmitter Only Mode 2 , Model Number SPMR5510
Mine worked well enough for me, but it's just not that much better than the little transmitters that come with RTF models such as the \\"Champ\\".  My advice is to save your money, buy a little RTF trainer with a short range transmitter, then get the DX6i later.  The 6 is a much better radio, with memorized trim and travel settings for 10 models.
