STANDARD RADIOS vs. COMPUTER RADIOS

I think you will find the economics of computer radios have changed in the
last 2-3 years. This is partially due to the advance in electronics and
partly because people are buying that second, third plane much sooner. We
have flyers in our club who have been flying less than 6 months who have 3
planes already. The cost has dropped so much, and the availability of ARFs
and high quality kits have made it cheaper and simpler to get the next plane.
There is little to hold them back.

I recommend new pilots go directly to the computer radios. If they start with
an RTF, then they use that radio to fly that plane. When they buy the second
plane, they get the computer radio.

A quality electric ARF parkflyer or simple to build kit, with the motor, can
cost as little as $40. A flight pack for that plane can be as low as $70.
You can put it in the air over a weekend.

An ARF 2 meter sailplane can be $90. The electronics to put that in the air
can be around $70 and can be completed in a couple of evenings.

In the glow and gas powered world these low costs and rapid adoption of second
and third planes might be different. I can't say.

BACK TO RADIOS

Just as computers have wiped out the typewriter, so the computer radio is
making the standard radio obsolete. Today, nobody buys a kid a typewriter
to type his school papers. They get a computer.


I have come to the conclusion that the only reason to buy
a standard radio is lack of confidence that you plan to go forward, or
the standard radio came as part of an RTF package.

Here is a quick look at some key points.

Economics - Let's compare - Tower Hobbies catalogue

Hitec Laser 4, std Radioand 4 standard servos - $120
Futaba 4 EXA computer radio, receiver, 4 standard servos $149
Hitec Flash 5SX computer radio, receiver, 4 std servos $156

Difference is $29-59

Looking at the Flash, you get 5 model memories so you can instantly switch to
any of 5 models without having to reset anything. If we ignore servos and
receiver, the Flash covers your next four planes for about $9 each. With the
standard radio you need to reset for each plane, carefully keep all planes
tuned identically, or buy a radio for each plane so you can tune it to the
plane and keep the settings. That would cost about $60 per plane for each
standard radio, or an additional $240. And with the flash you only have to
charge one radio and bring one radio regardless of which plane, or how many
different planes you wish to fly.

That's $36 extra for one radio that handles 5 planes or an added $240 to have
each plane's settings retained with a standard radio. And the Flash 5SX does
a whole lot more than just provide model memories. This is an excellent first
radio.

Big savings and enhanced flexability with the 6 channel computer radio!

In the Tower hobbies catalogue:

Standard Radio - 6 channels
Futaba SkySport 6 with 4 S304 servos and receiver for $149
Computer Radio - 6 channels
Futaba 6EXAS 6 Ch computer radio-same servos & receiver $179

For $30 the 6EXAS gives you 6 model memories and a whole pile of features
the SkySport standard radio can't touch, and you divide the cost over 6
model memories. The computer is cheaper and more convenient.

What else can these entry level computer radios do?

Split Ailerons/flapperons: -

You can install two aileron servos and connect each to a separate channel on
the computer radio. This makes it very easy to trim each servo to get each
aileron just right.

You can set up aileron differential, if you wish, to improve effectiveness
while reducing drag. Very popular on sailplanes.

Or let's say you have a plane with ailerons but no flaps. You fly the plane
normally. Then flip a switch and turn the ailerons into flapperons. Now you
can use your ailerons as flaps during landings. Flaps on a 4 channel plane
that doesn't have flaps. You can just as easily set them up as spoilers, which
are commonly used on sailplanes during landings.

Cool!

Coordinated turns - Mix rudder into your ailerons so you have a coordinated
turn. On a standard radio you have to do this manually. With the computer
radio you can do it manually too, or you can focus on the plane while the
radio handles the coordination for you. You can override the mix and add or
reduce rudder at any time.

Exponential, dual rates, model memories, channel mixing, digital trims and
lots more. Some of these features can be very helpful in getting new pilots
in the air.

Are computer radio hard to use?

No! In fact if you want, you can just use it as a standard 2, 3 or 4 channel
radio until you want to use the other features.

Take a look at this thread, starting at post 49. This guy talks about using
flaps as ailerons for flying and flaps for landing on a R/E/F sailplane.
Pretty cool idea. Can't do that with a standard radio!
http://www.rcgroups.com/forums/showthread.php?t=289216&page=4&pp=15 (http://www.rcgroups.com/forums/showthread.php?t=289216&page=4&pp=15)

So, for an extra $30 over a standard 6 channel radio, you get
a radio that handles multiple models and lets you do things that the standard
radios can't do. Go up a another $25-50 to the Hitec Optic 6 or Futaba 7C and
it is amazing what you can do and now you get 8-10 model memories.

Will you need this on the first plane? No, but they can be helpful.

Differential can be very helpful to a new pilot. Most radios that
come with RTF packages, and most standard radios don't have all these
features. You don't have to use them right away, but it is great to know that
you don't have to buy ANOTHER radio when you realize you would like to have
them. The price difference over a standard radio is now so small that for
all but the very few, the computer radio is now the economic entry level radio
of choice.

If you get into even semi serious aerobatics or sailplanes, a computer radio
is a huge benefit and for some things, almost a requirement to bring the plane
to its full potential. Even the pilot of a 3-4 channel parkflyer, or someone
flying a simple R/E sailplane with spoilers or flaps benefits from a computer
radio.

There is only one reason to buy a standard radio these days. "I don't know if
I will like RC flying so I want to spend as little as possible". Or the
standard radio came in an RTF package like an Multiplex Easy Star RTF, a Great
Planes Spirit Select RTF or a NextStar Glow RTF.

I have used Hitec and Futaba as examples here because I know those lines best,
but JR, Airtronics, Polk and others have entry level computer radios that are
a much better value than any standard radio. In many cases these entry level
computer radios will serve the needs of the pilot for many years to come.

Get a computer radio, save a bundle of money, get a bundle
of features and really have fun with your RC flying.

I'm all for computer radios.

Actually IMHO the only radio for most people flying planes or helicopters to buy right now only comes in computer form. There's a clue about the choice between non-computer and computer radios!

It's the Spektrum DX6. Unless you have some disqualifying need such as way over the hill range or more than 6-channels or such, today IMHO it's the only raidio to consider.

Of course, YMMV.

DX6 is a great choice for small helis, as well as electric planes and gliders under 60 inch wing spans. It would be one of my first recommendations.

AEAJR,

Could'nt agree with you more. I have been flying with an Airtrony Infinty 660 for 10 years, just had the lithium cell replaced last winter. I'm in the "pre-buy" stage for a new radio, so am waiting to see how soon everybody has a Spread Spectrum system. The DX6 lacks at least one item that is essential to me, if they release the XP6102 w/spektrum RF module, that's another story:)
Now, if I stay on 72 Mz, only Airtronics and Hitec are in the running, since they offer shift select for PPM FM. I think the "big guys" are missing the boat on this one. I'll accept fazing out my old FM RX's to go 2.4GHz, but not if I buy another 72Mz system:mad:

DX6 is a great choice for small helis....
I'm flying a BCP now and I'd love to get the DX6 for it, but If I'm going to spend money on a radio, I'd like it to be something I can use in the future as well. Why is that the DX6 wouldnt be o for a larger heli, say .50-.60 ?

Thanks

AEAJR
02-12-2006, 02:31 PM
They are concerned about the signal blocking characteristics of the larger glow motors. Although, on a Heli, isn't the receiver below all the motor equipment and gear stuff?

Might be an issue in inverted flight.

I read a thread not sure if it was here that you can put the dx6 output board and ant into a JR 6102 and get all the extra features of the 6102 while keeping the dual channel of the dx6

AEAJR
03-22-2006, 05:04 AM
I would not include that here. That is a sort of a modification of two radios and I would include that in a thread about what radio to buy.

Hi Ed,

I see your opinions on radios are getting stronger. (by the changed title of the text)

I couldn't agree with you more. I have a DX6, an Optic 6, and a Laser 4. The Laser hasn't even been used yet.

However, I should point out that a cheap but clean used analog radio from ebay might be a GREAT way to get into RC. For example, one would buy this, a trainer--> USB cord for use with FMS and one is all set for some real learning, without the expense & frustration of crashing.

Now, when the person is done learning on FMS, they have a functioning radio to use with his/her first plane. ;)

I bought my Laser 4 as a buddy box and possibly to lend out to prospective RC pilots. We'll see how that works.

It only has a 3 point throttle curve, I'm not a heli flyer, but from what I understand you'd want more points in most cases.

Hitec has announced that they plan to release a 2.4 GHZ module for their radios that take a channel module. These include the Optic 6, Eclipse 7 and the Prism 7X.

The module will also be tested and available for Futaba modular radios, such as the 9C.

Cool!

Ed,

I like the idea of the 2.4ghz and have been looking at the spektrum. Based on this announcement from Hitec would you recommend waiting?

I want to get the most bang for my buck so to speak and there are so many choices it is a tough decision to make.

04-27-2006, 03:32 AM
If you are a dedicated parkflyer pilot with no interest in sailplanes or glow planes, then go ahead and get the DX6. Great radio for electrics.

I have a Futaba 9C and a Hitec Prism 7X, so I will wait.

Hi Skiman,
Thanks for the link, I see how you get d/r on rudder, but no mention of expo, no biggie for the use the radio is intended for, while I have not been a park flyer, that changed about 30 min. ago when the Big Brown Airplane truck stopped by with a nice new slow stick, and other goodies,;) I have an Esskay 400XT on order from HL, so I bought the "glider" version with no power plant, 21 bucks at Tower, sweet. So's now I cana join da slow sticka Famiglia;) That'sa pronounced fam-eel-ya, to youse dat are Italian challanged:D, hey you eata the pizza, then you sez it right, OK, soundsa nice don't it.
Ed,
I'm with you on waiting for the new module based system, especially if you fly large slimers and electrics:eek:, oop's forgot where I'm posting, I've outed myself:o. I really look forward to seeing the upcoming 9 ch. from Hitec.
And now kids, tune in again next week for the next exciting chapter of RADIO WARS, and remember to drink your Olvaltine!

I would expect the long range, full features, lots of channels 2.4 GHZ stuff will be out by end of year either as complete radios, or as plug in modules to current radios.

9 Channel Futaba 9C on 2.4 GHZ flying a 4 meter sailpalane 1 mile out .... Cool!

Well, I followed a link from another board to this discussion. I am a noob pilot, about to maiden my first 4ch plane. I only got into the hobby a month or so ago. My first plane is a 2ch thrust vector steered twin motor push glider that cost me 30 bucks. That was just for me to have something to fly with, and learn orientation while I waited for the real thing to be finished building.

For my first real radio however I chose a 4ch 72Mhz standard radio. The Esky EK2 0404. And it was a matter of cost. I did not know if I would stay in the Hobby, and I paid 38$ for it. a computer radio would cost me about 3 times as much where I am. And not knowing if I would stay in the hobby, I could not justify it.

What I did thogh was to make sure the 100 bucks saved went into quality electronics in the plane. A good brushless motor, ESC and batteries, that can be reused.

Then I can always upgrade later to a 6 ch or more computer radio later. But I have to admit that I have some remorse over my choice. As I am heavily into photography, and I now I want to do aerial photography for fun, once I learn to fly...and need a fifth channel to steer a servo to act as shutter release.

Well, at least I think my radio is good enough to learn on. And the wife did not go as ballistic as she would do had I come home with a 100 dollar higher bill...but if you do not get a computer radio...at least make sure it has 6 channels....you may want to use the extra 2 channels, even if you only need 4 to fly your plane.

Neon 3 ( uses regular batteries ) = FREE, and you saved $11
on the rest of the stuff! You can buy the contents and throw the
transmitter away!!!! :D

=================================================
Now, you can argue $5 or $10 either way with my analysis, but it won't
change much. If you are looking for an entry level 6 channel computer
radio, these packages are a great value, and perhaps even better than used
prices.

Even if your focus is cheap, as opposed to value, you can get a new standard
radio for free in these packages.

I am going to order the E-Flite P-47 as my second plane. Obviously I will need a transmitter, receiver etc for it. If I was to buy a computer radio then what should I look at? I am interested only in electric at this stage. In the next couple of years can see my self collecting WWII warbirds and maybe even some WWI stuff. What would be a reasonably "future proof" system to look at. I dont want to be at the mercy of some salesman. Some prior knowledge would be much appreciated.

You left out THE most important piece of information. Your budget.

There is a list of very good introductory and somewhat more capable computer radios listed above your post.

One consideration is how many models you plan to have as you will want a model memory for each. Some of the radios have four, some have 10 and some have a lot more.

My Futaba 9C can have a virtually unlimited number.

If you can swing $350 for transmitter, receiver and servos, I would recommend the Spektrum DX7.

Spektrum DX7 2.4 GHz full range 7 channel radio - $349
Virtually same as JR 7202 but with 2.4 GHz transmission
http://www.horizonhobby.com/Products/Default.aspx?ProdID=SPM2720
20-Model memory, 2.4 GHz full range receiver and 3 micro servos and micro receiver, suitable for small electrics. Some switch assignment, 6 user mixes, 3-axis
dual rate & expo, 3-position flap. While this radio does not have typical
sailplane programming here is a post where one creative individual has made some
creative use of user mixes to develop some of the common sailplane mixes if you ever want to fly sailplanes.

I want to humbly add one aspect to this discussion:
Think of all the people who buy one of these inexpensive complete sets and then ask yourself if you really want to take any chances to crash your plane because of interferences. Not to talk about causing other people problems.
we are no longer living in times where only a few experts with a lot of patience built and fly a plane in a controlled environment (i.e. club).
IMHO 72mhz should not even be an option if you start (as I do) new and have not already a lot of planes with "old" receivers.
Granted, it is a pretty steep investment. But safety always comes first and has no price.

That is at least what I will do, I don't want to end up as a

Impressed to hear I have this kind of mind control.

Note that the "brown out" issues have nothing to do with the transmitter so whether you fly the DX6, 6i or DX7, you have to take exactly the same care in installation of your electronics. Make sure your receiver battery is adequate to the task OR make sure your BEC is adequate to the task.

BTW, these are identical to how you should set up your 72 MHz systems. It is just that the 72s are a little more tollerent of our mistakes.

If you can justify the cost difference of the DX7, and plan to fly more complex planes at a future date, I would recommend the DX7 over the 6i.

I missed this thread, I'm surprised at the start date.

I fly next to a school and there's fuels guys that show up now and again and the "newbs" always have non-computer radios. Some of these "newbs" have been flying for gasps years with these radios and on the trainers.
The reasons they're still on the cord could be easily fixed by a computer radio.
They both mention the plane being to sensitive.

When I explain the expo function on a computer radio and ask why they don't get one, I tell them they can get more flying time in.

They answer they don't know if they're going to stick with it.

They've been flying for two summers and had multiple planes but they're opposed to computer radios.

BTW, I had the chance to pick up a DX6i at the LHS. I didn't open the back to see if it was an E-Flite version, but I have to admit the early reports are right.
It does indeed feel "plasticky" and "cheap". The programming wheel is quite sensitive and it's easy to go past the option you want or choose the wrong option. But he menus are NICE.

I missed this thread, I'm surprised at the start date.



While the thread was started over a year ago, everything it says is still current, other than the fact that computer radios are even more affordable now and sometimes dirt cheap.

For example:

Just a few years ago, all radio packages were sold with standard servos and big
heavy receivers. One exception was the Hitec Flash 5SX which came with the
HS-81s and the Micro 555 receiver in what they called the glider package.
As a result this package became very popular with electric and glider pilots.
The
radio makers finally caught on and have started packaging more systems with
micro servos and micro receivers. I am only looking at packages with micro
servos and receivers that can be used in parkflyers or gliders.

Not Bad! Oh and full warranty!
=============================

Hitec Optic 6 - $210
http://www.hobby-lobby.com/hitec.htm

2 micro servos -----------------------------$15 each $30
Electron 6 micro receiver + crystal ( my favorite)---- $55
Misc other stuff in the package ---------------------- $20

Total for components $105

Cost for radio, charger Battery = $105 Not bad for a midrange 6 channel
computer radio, including full warranty!

======================================

FREE RADIOS - COME AND GET 'EM!

You are trying to get started on very little budget and can live with
a basic 4 channel standard radio with limited feature set.

Hitec Laser 4 - $115
http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXMYL6**&P=7 (http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXMYL6**&P=7)

3 micro servos --------------------------------- $17 each $51
1 Micro receiver + crystal -------------------------------- $40
Switch harness ------------------------------------------ $10
Misc stuff ------------------------------------------------$15

Total for components $116

Cost for radio, charger and battery = $0 FREE
Not bad for a basic 4 channel transmitter with Vtail and elevon mixing.
It also has ATV, servo reverse AND a trainer port! FREE!
==============================
Even lower budget?

You want to fly a 3 channel parkflyer or a 2-3
channel glider. You will definitely have to go used, right?
Let's see.

Hitec Neon 3 channel FM radio, servos and receiver $59.99
http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXLGF4**&P=7 (http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXLGF4**&P=7)

The package includes 2 HS-55 servos ----------$13 each = $26
Micro 05 receiver with crystal ---------------------------- = $40
Misc Stuff in the package ---------------------------------= $5
Contents of the package, if purchased separately - $71

Neon 3 ( uses regular batteries ) = FREE, and you saved $11
on the rest of the stuff! You can buy the contents and throw the
transmitter away!!!! :D

=================================================
Now, you can argue $5 or $10 either way with my analysis, but it won't
change much. If you are looking for an entry level 6 channel computer
radio, these packages are a great value, and perhaps even better than used
prices.

Even if your focus is cheap, as opposed to value, you can get a new standard
radio for free in these packages.

Each of these packages includes at least 1 year warranty and you
don't have to worry what someone else did to it. Try to buy a
comparable transmitter, used, for less than this.

While the thread was started over a year ago, everything it says is still current, other than the fact that computer radios are even more affordable now and sometimes dirt cheap.

For example:

...===========================
Maybe you want a little more feature rich radio

Spektrum DX6i. No channels pins to worry about, no channel conflict.
http://www.horizonhobby.com/Search/Default.aspx?SearchTerm=DX6&CatId (http://www.horizonhobby.com/Search/Default.aspx?SearchTerm=DX6&CatId)=

$160- Let's see how much the radio costs if you
were to buy the parts separately.

AR6200 micro receiver, no crystal required ------- ----$65
Misc other stuff in the package ------------------------ $15

Total
.................................................. ..........................$80

So you get a pretty feature rich 2.4 GHz radio with 10 model
memories, rechargeable batteries, and charger = $80 -
Not Bad!
=============================

...Any questions?


Ed,

The above is confusing. The $80 total (if bought separately) makes no sense. The link is to the DX6 not the DX6i.

He's saying the servos and receiver are around $80 when purchased separately, so the cost of the radio itself in the $160 package is only about $80, since you're getting $80 worth of other components in the box, too ($80 radio, $65 receiver, and $15 servos all in one package).

Now I understand the logic, but the DX6i does NOT come with servos just a radio and receiver.

Prof,

Thanks for catching that. I must have been mid edit when I hit the button. That analysis was originally based on the DX6. I updated it and apparently didn't finish the edit.

I messed up. :o But I fixed it. :) No one will notice. ;)

Got it. The DX6i is full range system as well with model match to prevent flying Plnae "A" with Plane "B's" program; friendlier interface; and it can use all of the availalbe Spektrum receivers. It kind of obsoletes the DX6. What's not to like about the DX6i?

OK, just for the newbies who don't have all the assumed knowledge, what does "Full range" mean?

OK, just for the newbies who don't have all the assumed knowledge, what does "Full range" mean?

Radios are designated as full range and suitable for large nitro aircraft based on radio maker assessing the range the plane can fly and still maintain control. Large nitro aircraft have large signal blocking nitro motors that can cause a momentary loss of connectivity which will require a reboot.

The DX6 is designated as an electric Parkflyer radio where flight patterns are closer to the transmitter mainly because the planes are smaller and you lose orientation at large distances. Parkflyers don't have large pieces of metal blocking radio reception. However, a DX6 parkflyer radio range is well beyond what my eyes can see when flying a small parkflyer.

The DX6i circuitry and design delivers similar performance to its big brother DX7 Spektrum radio.

The original Spektrum DX6 was marketed as a "Parkflyer" radio, suggesting that it had limited range. It was not recommended for large planes, glow planes or gliders.

They later introduced the DX7 which can fly any aircraft, so it was called full range.

The DX6i, in contrast to the DX6 is also considered full range, meaning it will fly any type of plane as far away as you can see the plane if you use the AR6200, AR7000 or AR9000 full range receivers.

Spektrum also makes the AR6000, AR6100 and AR6300 recievers which are considered to be limited range/parkflyer receivers. Again, there is no number given, so I'll say 700 feet for the AR 6300 and 1500+ feet for the AR 6100/6300. All have been tested at longer ranges than these.

There is no clear definition of "full range" but it is generally accepted to mean visual range. If you can see it, you can fly it. Call it a mile for a large plane, like my 3.4M wing span ( 11 foot wing span) gliders.

Ok, so despite what was said in an earlier post in this thread, later posts seem to indicate the DX6i would be ok for gas(nitro) planes, correct?

One additional question. I'm strongly considering the DX6i but also have a lot of interest in micro planes. Basically, I'm attracted to all planes for various reasons. Is the DX6i a good candidate? I ask mainly because I don't know what the micro or small foam planes tend to use for receivers. Another way to phrase this would be: How small of plane will the available receivers for the DX6i likely support? Small parkflyer only? Will I then need an FM transmitter for the micros (like maybe something coming with a RTF)?

Thanks. I'm anxious to get started and the DX6i for $175 delivered with AR6200 receiver seems like a great way to do it.

The Spektrum DSM2 TXs can use the AR6300 2gram RX that has JST connectors for light servos. That's pretty light.

And yes the DSM2 are "full range" which means they'd do fuel. If somebody wanted to do that \=

rpstar,

no other producer currently offers as many choices in 2.4 Ghz receivers as Spectrum does, especially in the micro range.

Heck the AR6100s are only 3.5 grams. Lighter than many 72 MHz Rxes. Short antennas help reduce weight.

I would expect the long range, full features, lots of channels 2.4 GHZ stuff will be out by end of year either as complete radios, or as plug in modules to current radios.

9 Channel Futaba 9C on 2.4 GHZ flying a 4 meter sailpalane 1 mile out .... Cool!
Good Lord Ed,
I'd need radar to locate the plane.....:<:;)

Hi , I'm new to the forum, and I'm getting some great info from the thread. I have a 41" Great Planes Electrifly Cub and would like to also fly a Goldberg Eaglet I have. I'm looking at the Tower System 3000 -6XM radio. It can be bought with transmitter, 8channel dual conversion reciever, charger, flight battery, less servos for $119 . Is this a Futaba radio with the Tower name or is the quality on par with the "Big Name" radios? I figure I can select servos to suit my application and have a decent radio set up to use with several planes. Thanks for opinions...Dick S.
