Radio control. Answered

I have radio control radio and receivers from different cars with different AM. They are all 49 mhz, can I change AM by replacing old resisters at  the right spot and put less resistive ones to make it work? Any way?

+1 To both of these answers. You could try replacing to coils and the crystal (I've considered doing this myself), but it would really be too much effort. There would also be other components to switch out in addition. It would probably be more expensive to try to do this then to find a cheap set online to use instead or a replacement transmitter/receiver (if you are trying to replace one with another).

The amplitude modulation is usually crystal based.

Different crystals make different AM? I know some crystals are bigger than others.

It depends. In most cheap toy RC systems the RC receiver/Transmitter are matched together and often encapsulated to prevent messing about with them.

Frequency is generally set with inductors (coils) and capacitors if using external components.
