Question on MhZ
 

I was floating through looking @ the different, Radio Controllers, and I came across this tidbit of information.

74Mhz is for Surface
50MhZ you need a license for
and
72MhZ for Airplanes.


Now, if these numbers are static wouldnt everyone's RC interefere with everyone else's? Or is the difference after the 72?
IE. a 72.56 would be a 56Mhz? and a 72.08 be an 8Mhz?

Can I use say a Futaba tX6A for airplane and sailboat usage? Or do I need a seperate controller?

Question on MhZ
 

It's 75MHz that's for Surface use.

Anyway all of those are frequency BANDS. There are lots of CHANNELS available in each band. The channel is defined by the bit after the 72. though it's not as simple as quoting the numbers e.g 72.13 is Channel 17, 72.55 is Channel 38.

So long as you are on a different channel you're o.k.

And no you can't use the same transmitter for surface and air (unless it has exchangeable frequency modules).
