[link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXGZS6&P=7]Here's[/link] what you need. This radio can be programmed to fly both positive and negative shift receivers and is synthesized to fly any channel on 72Mhz. Hitec is also releasing a 2.4 Ghz module late this year, so you can move into 2.4 Ghz and use this radio. I believe you could also use the Spektrum Air Module or the Corona 2.4 Ghz modules as well, so if you want the versitality of 72 Mhz and expansion capabilities, this is the radio for you. I have one and have been quite pleased. The price is great too.
