Mahonie, There are two major brands of the new 2.4GHz radios - And they are like Ford and Chevy

If your boyfriend is a "Futaba Man" He will want the FASST System Available at Tower Hobbies (The link above)

If he is a "JR Man" He will probably want the Spektrum System available at Horizon Hobbies

Look at his radios and get the brand he already has - if he has something other than JR or Futaba, I would recommend the FASST System
