Correct. If you buy a quality radio, from the 'big three' (JR, Futaba, Airtroncs), you can expect that they should be good to go right out of the box (after proper charging that is). Yeah, crystal oscillators will drift slightly, but they are usually are part of a crystal controlled digital phase lock loop oscillator system and are very stable at their center frequency.

My only issue with most of these new radios is that they come with 600mah batteries in the transmitters and 700mah batteries for the RX. I have replaced them all with 1650mah TX and minimum 1100mah RX. Just personal preferences, I like to have lots of battery power at the beginning of my flying day and continually monitor them for charge levels. That was taught to me from two 'pro's', one is an Airtronics freak, the other is a JR freak. Both say the same things. One is Master level pattern, the other is FAI level so they have enough experience behind their belts to make recommendations that usually have background.
