also keep in mind when radio shopping that a PRO radio is only as good as its driver. if you are a really good driver, and i mean really good, And have good digital servos with fast transit speed, you will fell a difference with a pro raido. if your just the mid pack guy or weekend basher the 3s will be just fine. even the cheaper radios have come along way. i have owned both the dx3r and i now have a dx3s.

its like golf clubs. if you suck at golf , pro clubs wont help you a bit.
