72 Mhz is dead - Long live 2.4 Ghz
Just my feelings.
The freq board will be a thing of the past .
I understand that you can not give away a 72 Mhz radio right now .
I was in the hobby shop the other day looking for two 6100 receivers
all they had was a 6000 and I did not want it , the guy behind me
bought it .
I predict that 72 Mhz will be extinct 6 years or less
I have a 9303 and more than 20 receivers that are being pushed
to the back shelf at a great speed .
To end on a positive note , my new DX7 is a wonderful piece of technology
I lived long enough to play with the good toys
What do you think ?

I went to the hobby shop yesterday, and I was lucky that they had a crystal that I could use, it was my second choice for channels, but they didn't have the other one. As I was walking out $12 poorer, I was thinking that there was one big advantage to Spektrum that I hadn't appreciated before. I'm probably not going to use the channel that I bought it for, but we have that channel radio at work, and I don't have a 72MHz radio yet. Unfortunately, I need the full PPM frame on one wire for a UAV, and Spektrum doesn't provide that. I basically bought the crystal so I could modify my receiver, don't know if it will ever fly.

i think 72 mhz has a few years left.
Yes, as more options open up in 2.4 ghz, and more people fly smaller electrics (which are generally taking over) the 2.4 ghz will become more popular and the 72 mhz less used.
But at this time I don't see a 2.4 ghz radio with 8 channels, 99 model memories, 7 programable mixes plus several built-in mixes, and cross-compatible with all brands that use the same frequency band for under $250.
(thats transmitter plus receiver plus 4 servos... and the NiCds for the TX and RX. Not a bare bones system... or just a module plus receiver to stick in some other maker's transmitter.)
Meet that level of capability in 2.4 ghz radio system at that price... then I'll think about switching.

Don't know what I am going to do with the 9303 yet , but if I give it away
it will be to my son .
When park fliers first came out they were on 27 Mhz . Now they are all on
72 Mhz . I have flown with a group of park flier's that fly beside a county
park and they have no idea of Freq control other than they are not on the
same ch's . We have several people that come out to watch us fly and talk
with us but fly at there home . I have and we all have planes that we treasure
and would be in pain if we lost . It is my opinion that 72 Mhz is fast becoming
unsafe . It is a shame but technology has saved the day and I for one am
impressed with this new and wonderful Spektrum world .

At our field, 2.4 Ghz is coming on strong, but we still insist on frequency board use, if only to show club membership.
The red flags are for 2.4.

We don't have any pin control for Spektrum at our field at all .
It is just not necessary . I just came back from SEFF with I think
about 400 pilots and no control on Spektrum . Also just talked to
people that came back from Joe Nall and I hear some where around
800 pilots and no control on Spektrum and no problems .
The CD at Joe Nall explained that you could have 80 Speckturms on
at the same time and then turn the 81st one on and the only thing
that would happen is that the 81st one just will not come on .

As matter of fact, 72Mhz will become safer as more people migrate to 2.4Ghz since less people will be on that band thus reducing the chances of accidental shootdowns.

I am really not worried about the 2.4 Spektrum people .
Park fliers are popping up that are not members of any club .
Talking with the local Hobby Shop he is selling park fliers to people
and they out number the club population by more than 2 to 1 .
And all the park flier systems are on 72 Mhz . He tells the people
about the club but we just don't see them . I recently went to work
for a large company but had my own business for 11 years . Some where
in the shop I would display a model most of the time . I found the same
thing to be true by more than 2 to 1 . I still wonder why these people
don't join a club . Part of the Hobby for me is to socialize with the other
fliers on the weekend .

non-club flyers have outnumbered club flyers for a long time.
a large percentage of the people who buy a park flyer get one or two flights, smash the plane and give up. So sales rate doesn't really relate well to how many people to expect to be trying to fly. If every person who bought a 72 mhz system within the last year wanted to fly on the same weekend the parks would be packed solid.
If all the people who bought 2.4 ghz systems within the past year in this area showed up at the park to fly at the same time... they wouldn't be able to all turn on at once without having interference with each other, despite the "magic" spread Spectrum systems.
But in real life... the air is pretty much empty...
Having pins for the 2.4 ghz systems is a good idea... because it tells the people at the field that the guy on the flight line didn't just forget to put a card up. From back at the club field's safety fence, you can't reliably see if the guy's transmitter even has an antenna unless you still have 20-20 eyesight. (I can about half the time... most others at the field can't at all)
Also it helps to indicate how many plan on flying, vs how many are just there to talk about flying.
And it certainly doesn't HURT anything to have the cards up...
