any one have old 75mhz crystal set. i have my old jr racing xr3 tx and rx but no crystals. i bought some on ebay but they didnt work. found out they are for silgle conversion(nor sure what that means but its not what my radio is set up for)
I have a crystal set, channel 62, new in the package, although the package is 90% destroyed. If you want to pay the first class postage you can have the set for free.
I would have no way of knowing whether they will work or not.
The thing with crystal is not every crystal will work in a radio most are brand specific..your gonna want a crystal that is JR racing ..you know that radio and rx will work on 27/75mhz... good luck in your search..if this was 8 years ago Id have a few but long since sold all my older radios..go 2.4 unless you gotta stay era correct
