    Got it!!! So simply making sure the Tx and Rx crystal are of the same freq aint going to allow you to change freq. Gotcha!!

    Besides 27mhz and 29mhz, the rest are not for remote control use. Using other band may cause interference to other wireless devices or u may get interference from other devices.

    The difference is most other devices may get annoying noise and suffer no damage, but for the r/c vehicles, u may loose it. The real risk is yours. Daddyhobby encourages the use designated freq band and follow the licensing requirements.

    Meaning if you have a 27Mhz Band radio, you can use any 27.***Mhz crystals. And if you radio is in 29Mhz band, then you can use all the 29.***Mhz crystals.

    thank bro, now I know... but how come I got the frq in my plane is 40Mhz? and 40Mhz is not in the chart, so does that mean I am using a illegal freq? so do I need to replace the crystal with a legal frq band?

    but i dont think there is a frequency of 18mhz or 47mhz. the radio set that we use to fly aeroplanes or heli does not produce transmitter or receiver on that frequency. the commonly produce frequency are 29mhz, 35mhz, 36mhz,40mhz, 72mhz.
    ic ic. because I found some cyrtsal of 18.432Mhz and 3.57Mhz at home. hence wonder if I can use them.
