Your right, that is why there are multiple frequencies available.



Hmmm....

Same thing here. One of the controls controls both (sometimes) the other controls only it's own?

The transmitters are crystal driven, so they should be pretty well on the money as far as frequency goes, but the receivers probably use some type of band-pass filter, which could easily be out of wack since SMDs and ICs often have wide tolerances....
Especially in clone where the quality control might not be top notch.

You say when the cars are sitting beside each other, is it ONLY when they are beside each other? If so I imagine it could be some kind of resonance effect in his cars receiver circuitry triggering your car? Kinda a long shot though, I'm not sure the physics are there for something like that to be possible.

I thought my problem stemmed from the fact that the frequencies were so close together, but maybe it is a more common problem.

Has anyone else experienced similar behaviour?
