well, i bought a 6exas and im not doing anything crazy if u know what i mean. My trainer worked great with it and my 4 star is working great with it, except the fact that i have not flown my 4 star yet, ground tests are good. Its really easy to use and u can program several models and it can do flaps landing gear, and most of the other fancy stuff. But how far do u want to go? for me the 6 exas is goign to work perfect. I mean eventually do u want to go into jets and more advanced planes or do u want to stay a little more low key. I know some people will disagree with me and others will agree. But mainly, it a great radio and if u have a pretty good idea of where u are goign than i say go for it. i wish that i went with the s3141 servos, amazing that each servo is $34 and the s3004 are like 15 however the price only changes 20.
