Martin, does that mean that the FASST system will operate on both 2.4Ghz and
72Mhz???
No. You could actually do frequency hopping and similar techniques at
72MHz but you'd annoy all the current users (and the FCC).
Techniques like FASST are similar to those that keep your (digital)
cordless phone from interfering with your neighbors' phones and any WiFi
that you and they are using.
All radio systems do is transmit information coded on some radio
frequency energy. One of the big tasks the receiver has to do is select
the wanted stream of information from every other one that's out there.
The original way -- and the one we've grown up with -- is by selecting
the base frequency that the information is encoded around, so you
'tuned' your radio. This is now very old school; we still do it for
older, legacy, equipment but its now not the way things are done, its to
inefficient.
One way of thinking about this is to raise the frequency of the radios
up a bit until they're so high they're using visible light. (Light is
the same sort of energy as radio, just a lot higher frequency.) Each
frequency -- channel -- corresponds to a different color. So the radio
we've grown up with is a bit like having a world where information --
say road signs -- are in different colors, with each person (or group of
people) having to use a color filter to pick what they want to see out
of what would otherwise be a lot of white light. Of course, we don't do
that in the real world. We use a mixture of color, shape and animation
to make a message stand out; this is our world so we don't think its
anything special. All that's happening with the radios is that they're
getting smart enough to use similar techniques.
The orange shirts thing is just a joke -- a playful dig; the idea is
that if you're wearing a shirt advertising a wonder product then you
really should be using same, not the product its supposed to be superseding.

that LJ said about "so that their FASST systems work???)
All I can say is it's going to create a nightmare for me when I do the NATS
launch matrix (Note to NATS Registrar: Need to find the FASST systems fast -
no pun intended - going to wreak havoc is we put them in and standard 72Mhz
systems in the same flight group)
Good Lift and Good-Luck to all at the NATS...I'll miss being there this
year!

For a real, unPhotoshopped, picture try:-

View includes both "FASST" and "Definitely a 72MHz antenna"....

PS. I don't know about the 'gay' thing, as you know there is no greater
bond between two humans than that a pilot and their timer so its easy to
mistake the relationship (at least for about 8 minutes).

Martin,
Take a look at the following link and the 3-4 subsequent pages.
Are the fellows in the orange clothing the same ones that you saw
at the SC-2 contest?
They seem to be a real pair to draw to!

I remember seeing the guys with the orange shirts at our (SC)2 contest
(the ones covered with "Futaba" and "FASST" and the like). Worth a
picture...they were quite obviously flying on 72MHz.

PS. I fly with a Futaba radio. "Works fine for me"

Bill and Darwin,
You know I love both you guys even though you wear those Orange
shirts, and I have to concede that it is possible to do more with 14
than 12. I want to point out that the discussion was 2.4 and
sailplanes, and I still feel IMHO that JR offers more flexibility and
better RX's for our competition sailplanes and large scale models
with
multiple servos and high power requirements. I also don't often
venture in to the large aerobatic arena so it would be unfair for me
to comment on that phase of the hobby. I do know something about
Helicopters, and have always found that JR has had the best
flexibility and options for programming. Even with all the
limitations
of the 12X over the 14, that guy Quique somehow manages to get the
12X to do enough that he is not embarrassed to show up at a contest.
Enough said I hope the Futaba is always good to you. Larry
