I just changed (reversed) my two Hitec RX crystals. One going to my Laser 4 (ch54) and the other going to my Focus (ch30). The Micro O5S single conversion receiver I switched from ch54 to ch30, and the Mini 6S single conversion receiver was switched from ch30 to ch54, and they both work perfectly fine after the switch. Will this last or should they be switched back?

The ch30 crystals say 72.390TF while the ch54 crystals say 72.870TF. Is this minor difference of concern to me in regards to reversing the RXs?

Glad I came across this thread, it will tell me whether I need to switch them back or not, even though they appear to work with the switch.
