27 MHz CHANNEL number frequencies:
26.995 - BROWN
27.045 - RED
27.095 - ORANGE
27.145 - YELLOW
27.195 - GREEN
27.255 - BLUE
It's been a few years since I was active in the AMA.
I should have know the colors would be found in the member's manual.
Thanks Red Scholefield AMA #951

I am the one that introduced the color coding to MAAC it was refused,So I
proposed it to AMA, they accepted it and 2 yrs late MAAC had ro do the same.
SO,27.995 Brown,,.045=red, .095 orange, .145=ellow, /195=reen, .255=blue.
Most of you young whippersnappers are not aware that the first r/c
frequency (besides 465 mhz..) was 27.255 mhz...it was the only one
for a while until we got the other ones from 26.995 to 27.195...and
FYI 27.255 is still a viable and legal channel...assuming you want to
share it with the CB people as it is a shared channel...being channel
23 in the CB world. I fly on 27.095 and 27.145 and NEVER get
glitched...it is like the six meter band..you have it all to
yourself.... Am using HPI 4 channel superhets AM (25 bucks on ebay)
along with Futaba AM modules which work in the later model
transmitters... I think I posted a thread on this site some time

80 years young..building and flying for 70 years...and first
flew r/c in 1948 (got it up and got it back!!!)
CBs? Do they still have those? I thought the noise levels got so bad they
became unusable for anything but, yeah Im gonna say it, convoys.
I'm 10/10 and 10/8 on the side.

Frank, I still have some .095 equipment and would not hesitate to fly
park fliers or even larger, powered sport planes on "orange."
I am using two of them in little things that I can just toss in the
air, as well as some sailboats and a powered launch (boat).
I guess my all-time, favorite .095 system was a World Engines' Mule.
This was single-channel, digital, proportional. The servo was built
on the receiver board in the "lil' brick" configuration.
The last time I saw this arrangement was in a $19 r/c toy I got from
Radio Shack. When I was teaching, I was getting tired of running a
long cable from lecture to slide projector, so I got the $19 thing,
left the little xmitter alone, and removed the "brick" from the toy,
mounted that in a little "Bud" box.
The arms of the servo pushed on a couple of microswitches and that
made the proper contacts on a 3' lead to the slide projector. I used
this arrangement for about twelve courses so far and that would be for
near 12,000 slide operations -- not one failure! All I have done is
put a new 9 volt battery in the xmitter each year, and recharge the
alkalines before each course. (My other choice was to buy a
"professional" version for near-$100.)
Someday, I might write a piece about all the things I have done with
my r/c systems during my ended-career. I even used one of mine in a
very dangerous radiation environment. Sticking the servos to test
panels with sticky foam and then using my xmitter to push buttons on
the panel was a whole lot cheaper than running all the cables and
adding parallel wires and connectors to the test panels.
Another time, I modified a radiosonde so it could be tethered at
altitude, and I used my r/c rig to switch between the humidity and
temperature sensors. (Normally, these would not switch without the
Guys, keep your r/c gear in mind on the job. You can occasionally
save the company a little money and this can be remembered during your
annual performance review. <g>

Showin' my age here, but i wonder how many RC fliers remember (or even
recognize) the pioneering efforts of the twin brothers Walt and Bill
Good, who were virtually the "Wright brothers" of RC aviation as we know
it.. beginning in the mid-1930s, when any RC endeavor required an FCC
license. Then beginning about 1963, Walt Good became the driving force
prodding the FCC to allocate the license-free 72Mhz band (plus the 75Mhz
car and boat band) we now enjoy and take for granted.
Certainly the story of "the brothers Good" should be
far more widely known in all RC circles.

Yes, but try teaching history to young people. I have. I quit. Too
many of them believe that if it didn't happen in their lifetime (and
recently) how could it have any effect on them. And if it doesn't
affect them, how important could it be? (This is a result of being
of the "Me Generation.")
Please don't start naming individual exceptions because they will be
just that -- "exceptions," meaning "contrary to accepted or
demonstrated norms." I have the National test scores over the years.)
This is sooooo true! The 'new' younger generation 'think' they know
everything, or if it doesn't pertain to them, it's just an 'exception. If
they don't STOP and pay attention to history, it has a habit of repeating
itself. This is just one reason why we still have wars between nations.
Listen to your elders! You may learn something that makes life a bit easier,
and less expensive.
I remember reading about Walt & Bill Good. My first RC outfit was a 'World
Engines' (Cincinnati Oh) single channel, rudder. (Being from Cincinnati, I
visited World Engines several times.) Then I advanced to a 'Galloping Ghost'
add-on to my single stick. Next came a 'Galloping Ghost' rudder/elevator.
Third was a Phil Kraft 4-channel proportional and finally a Micro Avionics
6-channel (single-stick, cradled in your left arm) proportional. I quit the
RC hobby in 1970. I was a supervisor with Philco-Ford at the time. Problems
at work and with my wife, both ended in divorce.
I'm retired now and my children are grown, so it's time to start where I
left off in 1970. RC-systems have changed a LOT! It's a lot better now! I
have two planes ready to go. My next plane (I hope) will be the Military
Stearman RT-17, 58-1/2" wingspan. My radio is a Futaba 7CAP FM/PCM
I've read and learned a LOT from this RC group postings.
Happy flying season to everybody!

Sure..but it was posted in a link on this site just this
week...however it is:
27.255 Blue (I think)
