    It will be better to buy a 6 or even 8 channel R/C, but expensive.

    hi,

    thanks docel for ur reply iam planning to get a 6 channel one but in the following link

    http://www.robotmarketplace.com/mark...rc-radios.html

    its mentioned that we cannot use it for ground robots will it be a problem

    if i buy 72Mhz one why iam getting this one is iam also getting servos

    with it for the same price of 75Mhz one without servos


    The FCC regulates that you CANNOT legally use 72Mhz systems for ground-based vehicles, but we get a lot of requests for 72Mhz systems for those of you flying model aircraft. Now you can purchase this system on the 72Mhz frequency from us as well. PLEASE DO NOT attempt to use the 72Mhz system for a ground-controlled robot

    1. That is for the US...... :wink:[/quote]
    2. 72MHz is VHF. Any signal >30MHz will fast approach Line-Of Sight property. This may not be good, let us say, if your Robot is behind a hill....
    So....Dont bother!! You may lose some range , but it happens with 27MHz too, due to interference from other 27MHz devices!!!
