spectrum" -- Futaba uses the frequency-hopping style of spread spectrum,
while JR/Spektrum use the direct-sequencing style. Both are
internationally-recognized types of SS -- there is a third (which I can't
remember at the moment) and several hybrid types. All must meet
global standards for SS transmission.<br>

I have a Futaba 9C currently on 72 MHZ. I see that both Futaba and Spektrum<br>
have conversion packages for 2.4 access. Any comments on either or both?<br>
(Spektrum is offering a good price right now!) Thanx-- Larry<br>
