To answer you question, Tactic sells what you need that will work and it's dirt cheap. http://www3.towerhobbies.com/cgi-bin...?&I=LXEKXX&P=7 Of course, there are small 72 Mhz receivers you can find used from Hitec or Hobbyking (synthesized) and get a fleabay radio for $20 since everyone abandoned it. I have several used 72Mhz radios and I still use my 9C and 7C, because those radios didn't get the memo they were outdated yet.
Now, if you can RETURN that kit, and get something else, well, read these threads and you decide.
