from what I can recall about the old crystals, you will need to find a tx and rx 75 mhz fm crystals if you want to stay period correct, they are all standard fitment size, just being able to find them could be a problem. I haven't looked into tx/rx crystals so I don't know how easy/hard they are to get a hold of.

If period correctness isn't of concern for you, I'd recommend getting a nice 2.4ghz system.

Well, you didn't say what brand radio you have. For Futaba, the crystals are definitely available.

That is for the AM 75mhz band, read the tech notes.

You may have a dual conversion or FM radio so you might need a different style crystal.

There is a specific crystal for the transmitter and a specific one for the receiver. They just plug in.
The model and a pic might help to help you....

For Cars, the 75Mhz and 27Mhz are the two frequency bands used. I don;t like the 27mhz band myself, as CB radios and a lot of other cheap RC stuff uses that band and it tends to have more interference. However, if you have a quality radion, this is less of an issue.

FWIW, a new FlySky GT-3b is about $37 dollars. The crystals run $15 a pair at Tower Hobby. The 2.4 Ghz radio can be linked to up to 10 receivers, and if hacked, 63 receivers. I have some old radios, and I find I just like using the newer ones.
