futaba 6EXA certainly has expos's and you need them particulary if your thinking 3D..I upgraded my old futaba 6 with the computer and I am now one of those that wouldnt dream of ever going back to non computer radios..I suspect hitec and jr 6's are extremely user friendly but at least get a 6..I own the 9cap and love it..both radios can fly more planes than I own or carry to the field..I use nimh batteries too as the programming etc eats your nicads and besides you get much more time and for me that means piece of mind when flying all day..
