The old RX 18s are all 4.7Mhz and use a crystals to match freq. if I recall correctly, I never had a 5.3 so unsure if they used RX18s so I could be totally wrong too. But on the chance I am correct youll need a matching crystal set for your RX and your TX.
Thanks much answers my question. Unfortunately I bought three of these thinking the 7.0 was newer than the 5.3s. If you anyone who wants/needs them I will send them.

If you have a 7.0 it is the newest version. It can’t bind to anything but a 6.0, 6.1 and 7.0 system.
If they have the older RX18 systems and they said it was a 7.0 then you got lied to. Your tanks can be upgraded to a complete 6.0+ system (TX/RX) relatively easily but it does require the complete removal of the old RX18 control board.
