Radio Advice
OK, I've been bitten by the bug and am trying to learn as much as I can before I buy the wrong thing. I am trying to determine a good "middle of the line" radio that is versatile enough to use as a beginner and have some room to grow. A current issue of a certain magazine has the JR Sport SX600 listed as a "best buy". The price seems almost too good to be.
Does anyone have comments about this one?
I'm open for other suggestions also. Like I said, I'm a beginner, so I don't even know what questions to ask.
Looking to buy within the next month to 45 days. My stepson will be with me this summer and am hoping we can learn together.
Any advice is appreciated!
Thanks in advance.

RE: Radio Advice
If you want to save money on the long run get a good radio that you wont out grow. I fly Futaba so my choice would be a 9C. If the club you fly at has more JR users then look at them. I started with a non computer radio, then bought a used basic computer radio....all before starting on my second airplane.
Benefits of a good computer radio.
1 multiple model memory. it saves the trim settings for each aircraft.
2 electronic trim switches. they cant be bumped out of trim while the radio is shut off.
3 Multiple mixes, small programs that make the aircraft fly better..you will learn about theses as you progress.
Check with the RC club you plan to fly with for trainer box compatibility.

RE: Radio Advice
What follows has nothing to do with brand of radio and everything to do with the type of radio.
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 Radio and 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-$36
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 flexibility 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/showt...6&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.
TRANSMITTER MODULES
Many computer radios in the midrange and upper range use removable
transmitter modules. These allow you to change channels by swapping out the
transmitter section. It also allows you to change the frequency range on
the radio. This might allow you to use the same radio to fly 27 MHz, 50 MHz, 72
MHZ and 75 MHz. So you could use the same radio for planes, cars and boats
just by swapping out the channel module. Quick and easy to do. Hitec,
Futaba and JR have channel synth modules that will allow you to select any
of the 50 72 mhz channels that can be flown in North America. There are also
radios like the Evo 9 and 12, and the Polk 6 and 8 channel radios that have
built in channel synth. If you want to avoid channel conflict, a computer
radio that can change channels could be a great asset.
Hitec has also let it be known that they will have a 2.4 GHz module that
will fit Hitec and Futaba modular radios radios.
http://www.rcuniverse.com/forum/m_3986179/tm.htm
There are lots of good reasons to buy a computer radio. 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.

RE: Radio Advice
Thanks to both of you for the replies. Maybe I should start a new thread, but I guess now I would like to hear from some of you out there that might have experience with the JR Sport SX600.......Is there anyone out there with that?

RE: Radio Advice
I have no experience with this unit. My stuff is all Futaba and Hitec.
But, JR Radios are excellent equipment. This one has 10 model memories and a lot of features for the price. I looked through the manual on the Horizon web site. I wouldn't hesitate to get it if I was starting out today.

RE: Radio Advice
I disagree with you guys on this issue. First of all no one has yet considered the complexity of a computer radio. It is much easier to set up and install a basic radio than a computer radio. There is enough to learn in this hobby for a beginner without needlessly steepening the learning curve.
As to economics: Consider this: All of the previous posters have purchased flight packs for their computer radios that will fly multiple models. These flight packs cost from between $95.00 to $110.00 each plus the crystal. If you can buy an entire beginner radio for $115.00 including flight pack and transmitter you will be WAY ahead. When you buy your next radio (computer) in a year or two you will have the flight pack ready to go and a spare transmiiter, just in case! The difference in cost between a flight pack and a complete radio is nill!
Furthermore, the radio is usually cheaper still when purchased as a package. I complete package such as the Hobbico Avistar is now $259.99 at my LHS plus you ge another $20.00 rebate for a net price of $239.00. Subtract out the price of the motor and plane and you will see that the radio portion of the package is about $80.00!!! Can't buy a flight pack for that!!
Save yourself some money and learn to fly before you make the leap to a computer radio.

On the other hand, when I tried to set up my Slope wing on a 3 channel standard radio I could not get the throws the way I wanted them after a week of fussing. I switched over to my computer radio and had it all set in 10 minutes. Much faster and much easier.
As for cost of the radio, let's take a look:
First, if you are planning to fly small electrics/parkflyers, then go
for a Spektrum DX6. No channels pins to worry about, no channel conflict.
http://www.horizonhobby.com/Product...?ProdID=SPM2460
$199 or less - Let's see how much the radio costs if you were to buy the
parts separately.
4 micro servos - perfect for small electrics -- $15 each - $60
1 micro receiver, no crystal required ------------------- $55
Misc other stuff in the package ------------------------ $20
These are all things you will want for you small electrics $135
So the radio, rechargeable batteries, and charger = $64 - That's all!
=============================
Now if you don't want the DX 6 because it won't fly glow or gliders, or
because you can't buy cheap FM receivers, then look at one of these. They
will all work with a short range 4 channel $29 GWS& crystal or a long range
5 channel $40 Hitec receiver & crystal for the next plane.
Futaba 6EXAS - $160
http://www2.towerhobbies.com/cgi-bi...I=LXJUV7**&P=ML
3 micro servos--------------------------------$15 each $45
1 micro receiver + crystal for small electrics ------------ $70
Misc other stuff in the package ------------------------ $20
Total for components $135
Cost for radio, charger, battery = $25 for a 6 channel entry level computer
radio - WOW!
====================================
Maybe you like Airtronics better
Airtronics VG 6000 $170
http://www2.towerhobbies.com/cgi-bi...&I=LXEUY5**&P=7
2 micro servos ------------------------------- $15 each $30
1 Micro receiver + crystal ------------------------------ $65
1 Electronic Speed Control ----------------------------- $25
Misc stuff --------------------------------------------- $20
$140 for the above - you are going to need them anyway!
Radio, charger, battery = $30 for an entry level 6 channel computer radio.
REALLY!
===========================
Maybe you want a little more feature rich radio
Hitec Optic 6 - $220
http://www.hobby-lobby.com/hitec.htm
2 micro servos ----------------------------$15 each $30
Electron 6 micro receiver + crystal ( my favorite)---- $65
Misc other stuff in the package --------------------- $20
Total for components $115
Cost for radio, charger Battery = $105 Not bad for a midrange 6 channel
computer radio!
===================
One more - A JR 6102 - $199
http://www.horizonhobby.com/Products...odID=JRP6654**
4 Micro servos - $28 each ....-....$114
Micro Receiver/crystal .................$65
Mis stuff in the package ----------$10
Total $189
Cost for radio, charger, battery = $10 - Why buy used?
=======================================
Or maybe you are trying to get started for the absolutely lowest price and
have very little to spend. 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...I=LXLGF4**&P=7
The package includes 2 HS-55 servos ---------------$15 each = $30
Micro 05 receiver with crystal ------------------------------- = $40
Misc stuff in the package ----------------------------------- = $10
Contents of the package, if purchased separately - $80
Neon 3 ( uses regular batteries ) = FREE, and you saved $20 on the rest of
the stuff! You can buy the contents and throw the radio away!!!! I
have two computer radios and I just purchased this package for a "keep in th
e car", or "take it on trips in my luggage", radio. If it gets damaged or
broken, I just throw it away and buy another package. I will definately
have use for the rest of the stuff in the package!
=================================================
Now, you can argue $5 or $10 either way with my analsyis, 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.
Any questions?

RE: Radio Advice
I have a question that hopefully someone can answer.
I just got my first Nitro RC and it came with an HPI TF-3 radio. How does the HPI radio compare to an old school KO Propo EX-5 and the Futaba Megatech JR (probably 10+ years ago). The HPI feels like cheap plastic in my hand but the two old ones are much sturdier, were made in Japan and accept rechargeable battery packs and have terminals to charge without removing the batteries. They're still digital proportional and on the AM 27 MHz band but appear to have more knobs and dials for "better?" radio tuning.
Do I stick with the HPI radio or would I still be safe or maybe better off using one of these older ones?

I should clarify, the HPI Radio isn't something you would buy alone, it came bundled with the HPI Racing Savage X Nitro truck. [link=http://www.hpiracing.com/kits/kitMain.php?partNo=858]link to truck and radio[/link]. So that begs the question, is the bundled remote better or worse than either the old Futaba Megatech Jr or the KO Propo EX-5
I believe it is this one with a different shell, AM 27MHz and stripped of any LED indicators or other frills, just the basic steering and throttle trim, 2 switches and also no charge jack. [link=http://www.airtronics.net/blazer.htm]airtronics blazer[/link]

I have a question that hopefully someone can answer.
I just got my first Nitro RC and it came with an HPI TF-3 radio. How does the HPI radio compare to an old school KO Propo EX-5 and the Futaba Megatech JR (probably 10+ years ago). The HPI feels like cheap plastic in my hand but the two old ones are much sturdier, were made in Japan and accept rechargeable battery packs and have terminals to charge without removing the batteries. They're still digital proportional and on the AM 27 MHz band but appear to have more knobs and dials for "better?" radio tuning.
Do I stick with the HPI radio or would I still be safe or maybe better off using one of these older ones?

Today, most 27 mhz radios that I have seen are FM, not AM. But I don't run trucks or cars, I fly planes and the 27 mhz radios are FM.
What benefit would you seek from changing to a 10 year old radio. Have you tried them? Do you even know if they will work with the truck or will you have to swap out the receiver too?
Most 27 mhz set-ups today are low cost, dedicted to the model type radios. If you want to go to better equipment you would go to 75 mhz FM for your truck. 72 MHz FM is for planes.

RE: Radio Advice
I just purchased the JR XP6102 6-channel computer radio and couldn't be happier. I have flown with the classic JR F400 basic transmitter for the past three years with two models and finally decided to step up to a computer radio. This radio is the perfect transition...not overbearing with stuff to learn but at the same time has enough memory for 10 different models and has all of the fuctions that a beginner/intermediate will need (dual rates, exponentials, gear and flap switches). So far I have nothing bad to say about this radio...I would highly recommend this radio. Any questions feel free to let me know!! Happy flying!

RE: Radio Advice
Swampworks, To answer your original question. I did just purchase the JR sx600 radio kit. It is a very nice radio system. I started with the JR 4 channel but wanted to experimant with the comuter features which I am starting to grasp. the menu systemn is easy to click through and change. Plus the 10 model saves will be great for the other winter build projects coming. The SX600 is a great radio to transistion through. You can use it a standard radio just fine out of the box, but use the other features as you gain knowledge from experienced guys at the field. Plus the older 4 channel box of mine can now be used to help a buddy get interested in the sport with a $8 cord. ( adaptor cord for connecting other brands also available) If the price is in your budget I say go for it.

This is a very entry level computer radio. very limited list of features.
Does this sound like the one you have.? Is this it? The package at the link comes with 4 standard sized servos and a large receiver which would not be useable in a small electric plane, but would be fine for a .40 glow trainer or larger.
Key feature list:
All features of the S400
Digital computer precision
Dual rocker switches
Dual rates
Exponential
10-model memory
Travel adjust
Sub-trim
Flapperon mixing
V-tail mixing
Trainer system
Other comptuer radios have longer feature lists, but this covers all the basics. Good luck with it.

RE: Radio Advice
9 channel, Spend the money now!!!!! With all things considered. In the end you will save money not having to buy another transmitter. I wish I would have bought a 9 in the beginning!!!!!!!!!!!!!!!

RE: Radio Advice
Same here. I bought a JR8103 and soon had 3 6 channel computer radios and a 5 channel radio collecting dust. I spent a lot more money than if I had bought the 8103 to begin with.
I'd get atleast the JR6102 or the Futaba 7C as both have quite a few nice features. If the money is available get the JR9303 or the Futaba 9C both are sweet and will last you for years to come.

RE: Radio Advice
If you have an interest in sailplane flying, another consideration in selecting a transmitter is its power consumption. It is not unheard of to fly a sailplane over an hour at a stretch. I'm not sure how the major brands compare now but ten years ago there was a great difference in how long the battery would run a particular transmitter. I chose a JR transmitter partially for the reason it would safely operate more than one and a half hour on a standard battery pack.

RE: Radio Advice
Four servos is what you need IF the plane you are planning is set up for a single servo for the ailerons, otherwise if it is designed for individual servos for each aileron you will need a total of five servos, this assumes you are talking about a normal sport model not a giant scale where you may need muliple elevator servos. Good luck.

Glow uses a servo for the throttle. electric does not.

RE: Radio Advice
thanks for the advice so far
i'm going for gas ie uses methanol
also how would you configure the single servo to get both ailerons function

RE: Radio Advice
Depending on the size of the plane, one servo drives both ailerons directly or through torque rods. Very common configuration. However, for large planes, it is usually easier to just have two servos. You can Y cable them or, if you have a comptuer radio, you can put each on its own channel.

RE: Radio Advice
The case has been strongly made in this thread for computer radios. But why does the Futaba computer 6EX have to be bought for either a plane or a heli. Seems the computer could take care of that? It does in the Spektrum DX6, right?
