Default how do you know when your crystals are buggered?

Can someone please explain to a complete novice (me ) what crystals are for, how they work, and how you know when they need replacing?

Thanx!

Crystals are for changing the frequency of your radio. They work by vibrating (internally) at the set frequency, so for that reason are quite fragile and should be treated with care.

Cared for well they should last indefinitely, although if your car has radio problems they may be the problem.

Or if someone else is on the same channel, you can switch your transmitter & receiver set to a different channel/frequency. That way you can run multiple vehicles together. Keeps the signals separated.

Tracks typically have a board with closeline clips marked with the various frequencies/channels. Get the proper one BEFORE turning your radio on, so you don't screw somebody elses car up.

They need to be replaced NOW with a 2.4Ghz radio....

That was the greatest thing that got me interested in racing again....

How true. 2.4 has done wonders for racing. No more radio impound at races.

I don't think 2.4 is allowed in Australia?
