Re: [RCSE] How long will 72Mhz remain open?

[Simon Van Leeuwen]

To put a finer point on this, as 2.4 continues to capture the (sour) market 
it opens the opportunity for continued infiltration of RF-based toys without 
any policing. In other words, not only is this (lower) bandwidth 
unattractive to anyone other than it's original intent, the controls that we 
(as a whole) have exercised will dwindle.

Probably a long time.  But they're a governmental agency, so who
knows?

Our channels are too small for FM voice transmission.  They'd be
useful for pager operation, but pagers have been largely replaced by
cell phones anyways.  If the FCC can take back the 72 MHz pager
frequencies, then that 1 MHz chunk of bandwidth might be useful to
somebody, but short of that, I don't see too much non R/C demand for
our 72 MHz spectrum.  And any new usage of the band will have to
content with existing R/C gear still being used -- illegally if the
band is given away, but does that really matter?

However, the local Fry's sells toy helicopters on 72 MHz.  It may be
that in a few years 72 MHz is unflyable with any `expensive/breakable'
plane due to the toy R/C planes/helicopters that have popped up
everywhere.  It seems quite likely to me that the R/C usage of 72 MHz
band may be *increasing* rather than decreasing -- for every one of
`us' there's a bunch of kids with R/C toys.  They're mostly on 27 or
49 MHz for now, but this could certain change, especially once they
decide that they need more than six channels ...

[RCSE] The REALLY BIG deal about 2.4

[Jim Laurel]

As populations grow and expan into formerly rural areas, land suitable for
use as flying fields is becoming increasingly scarce.  And having to keep
fields at least 3 miles apart to ensure no channel conflicts reduces the
possibilities even further.  The biggest impact of 2.4 is that flying fields
can now be closer together, which means that new fields will be possible
that simply weren¹t viable before.

All the technical arguments notwithstanding, 2.4 will be instrumental in
helping us to solve our number 1 problem: a rapidly dwindling inventory of
places to fly.

Bubba does not have unlimited resources, nowhere close. Bubba choses to
expend some of the resources he has on toy planes. If Bubba did have
unlimited resources he would be arriving in Muncie in a small jet full
of toy planes and renting a nice convertable to fly XC with this year.
As it currently stands Bubba is driving a Honda minivan that is actually
owned by a bank to Muncie and scrounging for a pickup truck or a
convertible.

Jay -

I haven't found the response of my 2.4 systems to be any faster than my
72 mHz system. Many of the older 72 mHz systems are slower, but that's
not inherent in the frequency. Yes, 72 mHz Nyquist rate is WAY lower
than the rate for 2.4 gHz. A properly done 72 mHz system still transfers
data at a much higher rate than you can process so it doesn't matter.
Some of the 72 mHz systems are indeed slow, but some of the newer ones
are quick. Then there are installation issues that can slow your system
down. 

Bottom line? 72 is fine.

Bubba

You guys can feel the difference from faster servos, servos with higher

Re: [RCSE] 2.4G lag time reality.

[LJolly]

Paul, 
In the case of the Spread Spektrum systems you are absolutely correct. You  
will also not be able to take advantage of the Global Unique Identifier that 
the  allows the dedicated 2.4 systems to recognize a dedicated binded model 
setup.  Larry

[RCSE] 2.4G lag time reality.

[Paul Breed]

One area that makes this fuzzy is the 2.4Ghz add on module.
If the module plugs into the back of what was once a 72Mhz system it 
will not gain you any

lag time advantage. It may actually increase the lag time.

As the 2.4Ghz module is reading the pulse stream from the 72Mhz tx 
and then sending the commands.


If the TX is natively transmitting 2.4G and does not have a module 
then one could
expect the lag time to be better. But if you are using a 2.4G module 
in a 72Mhz Tx then no dice.
there is no way for the 2.4G module to know what is happening any 
faster than the
PPM pulses that go to the module. This is the same PPM stream that 
the RX used to get minus the
RF path. and the RF path is instantaneous in comparison to the 20msec 
pulse rep frequency.

Re: [RCSE] " What's the big deal about 2.4? - Lag...okay now we are getting ...

[David Klein]

The increase in responce is comparable to using fast servos.  I can without
a doubt tell the difference.  I fly planes with fast servos and rearward
C.G.s  I also fly planes fast as well as slow.

But you do have to realize that ths latency is before the servo.  So whether
the servo is fast or slow, or the plane is fast or slow, the latency is
added on.  It counts.  72 MHz is good.  a 368 servo on your elevator is
good.  But a 3421 is faster, and you can tell.  So you can tell with moving
from 72 to 2.4.

But like everyone else said, it isn't a big enough reason in itself to pay
good money to move to 2.4.  It is however another very valid reason 2.4 is
better than 72.

So for now, most of my planes are still 72, but a few are 2.4.  I like
2.4better, eventually all of my planes will be
2.4

Yeah! Will the pizza Box get a 2.4 Module? 


Pretty please. Anybody?

RE: [RCSE] " What's the big deal about 2.4? - Lag...okay now we

[denoferth]

Lag time? This is starting to sound like the argument the “experts” 
spouted regarding muzzle breaks on firearms. Those esteamed gun scribes 
maintained the projectile, theoretically, was long gone before puny 
human reflexes could possibly detect any reduction in recoil. They were 
able to get away with that opinion until more shooters actually tried 
using muzzle breaks as they became more available. Now these pundits 
are “experts” in some other area, maybe response time.  My own limited 
tests, which admittedly are not very scientific, seem to show a 
convincing difference in both smoothness as well as response time. The 
only two planes I have duplicates of are Litesticks.  Placed side by 
side, with identical throws, voltage, servos, etc the surfaces show a 
real difference between 2.4 MHz and 72 MHz. I also tried it with 27 MHz 
and the response seemed the same as with 72 MHz.

Jack, check with Jack Iafret as I think he has been keeping up to date with 
Profi 4K (2.4) things.

RE: [RCSE] What's the big deal about 2.4?

[Daryl Perkins]

For those of you selling off your Stylus, or Styli (pl) due to 2.4,
Airtronics will have a 2.4 module and receiver very soon. I can't nail
them down to a date, as they're also working hard on our new 10 channel.


XPS also sells a module for the Stylus, and I have been using it in my
BumbleBee Supra with very good results. 

Airtronics guys, sit tight the best is getting even better. 

Sh don't tell anyone.

[RCSE] What's the big deal about 2.4?

[Charlie]

The big deal for me?
Because of the  huge surge to go with 2.4. There is a lot of discontent towards 
the old 72 MHz.  And pilots are selling off the 72 stuff everywhere... 
I am enjoying the low! Low! Prices on Stylus radio's and radio accessories!
I think it's all good! It's a win, win situation. As we speak, the number of 
frequencies we have to control is decreasing!
I may go with 2.4 in my gliders. Since I do fly at large contests, the 
frequency security makes sense. 
But locally I fly at well controlled sites. And besides, I know who is on my 
channel around here. We are a tight group, and not that many pilots. 
I do look at it on the practical side as well.. I have about 20 aircraft that 
are loaded, and ready to fly.. I thought about how much it would cost to change 
out all the receivers.. I just laughed!
I think I will be ok with 72 MHz for awhile.  ')
Cheers
Charlie

Re: [RCSE] What's the big deal about 2.4?

[Albert E. Wedworth]

Well said David!
I totally agree with that!
What we do is so amazing. Most folks don't get it.
But I still wouldn't change what I'm using right now.
If I was to buy a radio it would be a Graupner MC 12 or 24(JR).
now, I would guess that could be 2.4.. I'd still have to see or hear of 
better results.  As of what I'm hearing now ... NO Way!   
Ant gona change!  I'm gona stomp and wine till I get My Way
( I don't mind standing around with the guys B.S.ing
 till I can fly )
Old school I guess.
Cheers

$229.95 for Airtronics RDS-8000, 8ch Tx, Rx and battery
charger combo.

>From now until March 10, 2008 Hobby Club will donate
$50.00 from each of the sold systems to the US F3J Team attending the 2008 
World Championships to be held in Turkey.

Andby the way .the Rx antennas are 7-3/4" long

  The current 2.4 excitement is partly deserved and partly justified.

  At the moment it gives rc pilots a new freedom...it has taken frequency 
consideration and a need for its administration, concern out of the equation of 
rc soaring...in a way its like there isn't radio waves being used as part of 
our hobbyits as though we are preparing a free flight airplane, there isn't 
any thinking about 'channels'.  

  That freedom means that our minds to can shift to other components of the 
flight when we come to the field...and preparing the flightthe absence of 
radio.  We still have controls to fool with but that's where it stops. 

  Having said that, 72 has worked safely, does work safely and will continue to 
work safely. Arguments could be made that if anything it will be even safer and 
easier to use, with the drop in its population of users.  Sure the doomsday guy 
will throw out the possibility that channel-consideration by pilots will be 
come lax ...making 72 a dangerous gamble.  Clothespins and freq boards will 
come to disrepair and with it the discipline we all learned to respect as 
gospel on the field. Possible, but not realistic.

  I highlighted "at the moment" because 2.4 is in its sailplane infancy, ( and 
actually the term 2.4 is only a nickname for these kind of systems because they 
all currently share the same rf frequency right now there are at least two 
kinds of systems using 2.4) we can't tell for sure what the future holds when 
the 2.4 population expands course with the population of sailplane pilots 
decreasing as our age increases:-(

  What price that freedom?  About $650 for the TX and one RX.
