Changing Frequncies?

[Need4Speed210]

I just posted this here replying to their topic, just thought Id give everyone here a heads up. ......... Anyone have any ideas? Still thinking myself...

I wasnt going to let anyone know about my 'theories', but since I dont really have the resources right now I figured Id let someone else a try at it. First off im only 15 and my electronics knowledge is probably just the tip of the iceberg, but with what I do know, and common sense I thought of a few things... The car NEEDS atleast 1 component that regulates a frequency (27, 35, 57 etc) Even if this is not a full size Xtal, its most likely something that can be changed, seeing as it would make more sense. All the chassis seem to be exactly the same, same layout, just a different component governing freq. Theres only 1 Xtal, and thats for the tX. This means that there is most likely one component that changes frequency reception for the car itself. Although all the chassis seem the same, there must be a different component dictating freq. After all, you cant just change the tX Xtal, and the chassis will magically respond to that signal.- No, there needs to be something setting a base for it to understand. I dont want to sound like a scientist, but heres what I came up with-

Im thinking, this component must be, or must directly be related to the pot. As others have said, this seems to slightly adjust the freqeuncy with a seemingly small range (3-5Mhz?) From what I understand, pots are variable resistors, turning them does something like slide a connection point allong a resistant wire. This being said, I formed 2 possible answers.:

1- Frequency in the cars, must be wired in a way that different pots determine the frequency. Pots are variable resistors right? If adjusting one gives you a 3-5MHz sway, a say, different resistance wire, or guage, may determine the frequency.

2- A component directly related or very close to the pot determines the frequency, then sends it down to the pot for fine tuning. This could possibly be a mini Xtal, or something else. A schematic would REALLY REALLY help here.



Well anyways, thats what I thought up. Wouldnt it be DAMN cool if we could get like 10-15 cars going at once? (I KNOW I cant get whatever components required for different freqs, just determining what they are may take a while) Be welcome to critisize my thoughts, or try it yourself, just let everyone else here know!
