    I've just purchased a Nitro RC car off of my friend, I know a lot about the engines/how to prime etc, but...

    Not about the servos and receivers etc, my question is all of this frequency stuff like 27hz, 48hz, 2.8 ghz.

    I think the hz is the channel it runs on but what is the range on these types of receivers etc?

    hi dave,

    i used to have a radio controlled electric
    scale model of my sports car way back in the 1990ties.
    never was into nitro, though i love the technique
    and engineering of them.

    i was into radio ham things and dx-ing too.

    i am by no means an expert though..

    to answer your questions..

    27hz, 48hz, 2.8 ghz

    what you refer to is the frequency of the radio control
    system. in compututing we have bytes, kilobytes, megabytes
    and gigabytes.

    in transmitters it is herz, hz, kilohertz khz, megahertz mhz
    and gigaherz ghz.

    rc systems have to work in a frequency band, that has been
    assigned for that purpose in the country you live in.

    traditionally this was 27 mhz.

    1930ties technology.
    recently other frequencies were added. the latest is in the
    ghz range, more reliable, more high tech.

    if you buy a rc transmitter it will have sufficent range.
    more than a mile is not needed as you have to see the car
    in order to control it.

    i recommend you google rc systems, or visit manufacturer`s
    sites, like this one

    to get you started..

    Thanks for your info nodnar, really helpful.

    I've decided to upgrade to a 2.4GHz controller and receiver, probably with a crystal; and keep my old servos.

    you`re very welcome, Dave..

    if you go that way you can use it to control a new model in the
    future too

    with this in mind give a carefull thought to the number of channels
    you might need in the future.

    [ if you buy a 2-channel outfit now, you may have to buy a new
    one if your next project requires three channels, many systems cannot
    be upgraded, ]
