    Dear friends:

    I have two romote car cars.
    the first one is 40MHZ another one is 49MHZ in the receiver.
    what is the main difference from them?
    is it the distance from control to receiver? 49MHZ is longer than 40MHZ?
    thx for your help!

    Distance is not relevant, except for the fact that if the car is far
    enough away from the controller, it will not be able to receive the
    signal (too week).
    That distance could be a few hundred feet, or a few hundred feet, or a
    few thousand miles.
