8FG, Aurora 9, or X59303?

Well... Time for an upgrade from my dx6i... I am about out of model memory. The three radios I am choosing from are the Futaba 8FG, Hitec Aurora 9, and the JR X59303. Any Ideas?

Not sure about the "JR X59303," but both the 8FG and Aurora 9 are great radios, though for somewhat different reasons. Either is a good choice, in my opinion.

I have the 8FG, and would buy it again if I hadn't already. I can personally highly recommend it from first hand experience. If you have any specific questions about it that you'd like answered, feel free to ask either here or in the main 8FG thread.

I'm sure they'd address any questions you have about the Aurora 9 in that thread as well.

If you already have near 10 planes on DSM2/DSMX then you may want to stay with the compatible 9503. Receiver costs really add up.

Do what you wish but 3-pack Optima-6 rx's make things reasonable.
I looked at a thread for running the Spektrum module on the A9 and it takes a few cents worth of components and "nerve". I may try the conversion and then may have 49 spare sets of components for $2each and a stamp, some day! ........maybe someday.....

They all have advantages and disadvantages:

8FG has expensive RX's and no telemetry, but it's a very solid radio with good features.

Aurora 9 has much cheaper RX's and telemetry, but it's response time is slow compared to the others. This doesn't matter as much if you aren't playing with helis. Also, you can't buy a knock off RX if this matters to you.

X9303 is a good radio with the best RX prices/options, but the spektrum platform is a little more sensitive to having a good RX installation. Now that DSMX is out and all new spektrum RX/TX's support this, this will probably not matter as much. This radio doesn't have telemetry either, nor is it software updatable.

Another option is the DX8. While they have had their troubles, they are sorted out now. It has telemetry, cheap RX's, good menu system, software updatable. This radio also has very fast response times, but lacks decent sailplane support, and the charging system is pretty silly in my opinion.

Personally I wouldn't buy a non-software updatable radio, want to have telemetry to tell me my RX pack and link status, want to have very fast link speed since I do heli's and tight 3d, and I want reasonable RX prices. Only one of those options listed meet my requirements so I bought one.

I fly helis with my A9 and 3D with no problems. I also use it on large 3D airplanes, sport planes and foamies and it works just as good as my DX-7 and JR X9303 did.

The JR 9503 is a great transmitter but get the latest JR technology with the Jr 11X. Haven't seen an issue with it yet!!

All are good candidates
8FG gets you the most channels (10+2)
A9 gets you a touch-screen interface and integrated telemetry
JR9503 gets you the best selection of Rx in terms of features, specialised applications and price

I ama die hard Jr fan and love mt XP9303 but I have a feeling that I will not be going the Jr route the next time.

The reasons for me (in addition to what has already been said) are:

1. I do not like satellite receivers. I have heard that the base receiver will not work if the wire to the satellite disconnects/ intermittent in flight. You lose everything from a bad satellite connection. Besides, the satellite can be rather large to place in sailplanes and small planes. Dual long antennas are easier and still give diverity.

2.Those short antennas are opposet ends of a single dipole antenna and, in composite planes, it can be difficult to place outside. Sure you can spend an arm and a leg for a satellite receive with a long antenna but I feel they should just switch all of them to long antennas. I prefer the Futaba dual antenna with some length. Two different places at right angles seems to make for the easiest install. I know the 9 ch Hitec has two but the rest are those single antenna BODA blobs. I do not relish sticking all that out a fuse. Sure some don't but the big blob is the other half of your dipole.

3. They are starting to make Futaba clones so cheaper alternatives are available. Only DSM2 offers this and personally, I would rather only use DSMX receivers.

4. Brownout. I think Futaba has the lowest. Need to be too dilligent with components for my blood with Spektrum. If your servos are getting old and and start to draw more current, eventually, you could have a brownout which would be sooner than in the Futaba.

5. Fit. Love my thin case on the 9303 so the 9503 is awesome. Easy to reach everything. Very comfortable to throw DLGS with. The Futaba is flatter on the surface but just as easy to hold and throw DLGs with. Do like the Aurora 9 with their rubbery texture. A Little thicker but not by much and also can spin with a DLG. I find the 9303 very easy to enter data with the push scroll wheel. Heard the 8FG is a little harder with the mutli touch button thing and the Aurora can be super easy, if you like a touch screen. Some had issues with sunscreen or bug spray and touch screens though. Not sure I do not like any of the three. All fit me well and are easy to use - just different approaches to a common problem.

On the other hand, DSM2 does allow for data logging to determine if your receiver install is working well. No other offers this - not even DSMX. Can't do it in a hopping senario. Another plus is the BNF stuff but since you already have a DX6, your done there.

Also, if you get into contest flying and a site has issues with one brand, having a different could turn a bad weekend into a flyable one just by swapping out receivers.

For me, to help stave off making this decision and since my XP9303 is module based, I went FrSky. It seems to me to be a cheap alternative with similar features as Futaba that I like, is reliable, and offers telemetry for some additional fun.

Best of luck. To me, I think Futaba would be the best way to go. Isn't the 8FG a 12 +2 channel and isn't it software upgradable (soon) to have telemetry? I thought it was. Might want to verify some of these things in the 8FG thread.....

I would have to say the A9, I have been using it all year with my 3d planes and had no problems. And I have not even upgraded it to version 1.08 yet.

The receiver technology has come to a point that the servos will quit working long before the receiver stops working. Futaba, XPS and others have receivers that will work down to less than 2.5v. Most servos quit working long before the voltage reaches 2.5v, somewhere in the neighborhood of 3.5v to 4.0v.

My Hitec Aurora receivers will quit working at 3.5v IIRC but it really doesn't matter because the servos have already quit working by then anyway.

The only real solution to brownout issues is not to keep lowering the minimum operation voltage for receivers but to use a adequate power supply that provides adequate power for the entire system, not just the receiver. Whether it's older technology or newer technology, a inadeqate power setup or low battery will cause "brownout" problems.

I guess I just like the greater margin for voltage drop the others have.

Are you aware of the SB Hitec has issued about NOT using fiber optic kill switches with your radio?

Don't know if you fly gassers or use those switches, but it's causing some consternation over on FG....

For the OP;
Having the models you do would suggest that staying with the Spektrum/JR 2.4GHz radios would be the most economical. They also have by far and away the biggest selection of rx's for various applications of all the manufacturers.

As noted, the DX8 has had some teething problems but those seem to be sorted out with the latest SB. It is very different than other radios I've used from a programming and capability standpoint, lots of radio for the money although I too am not impressed with the battery charger, it works but it's a bit funky for my tastes. Also as note, no dedicated sailplane programming.

The 8FG is making noises with the new Super upgrade and you can update the regular radio to basically double the number of available channels, but the programming isn't significantly changed and I think you have to run the new S-bus rx's in order to use those extra channels. I'm not a fan of Futaba support in the USA.

The Hitec has some neat features but the number of available rx's is limited ans as noted, it's the slowest radio of the bunch. For the most part their CS is excellent.

The X9503 is a really nice radio but getting a bit dated with no SD card slot nor ability to do software updates. That aside it feels good in my hands and the additional features and memory added from the X9303 make this radio a good choice as well. It CAN use the telemetry features built into the new Spektrum stuff using the TM1000 module in the model, but you have to have some sort of "I" device like an iphone or ipad to get the readouts, they don't show up on the radio.

The 11X may be the best bang for the buck of the bunch with capabilities approaching the 12X at a bunch lower price and it does have an SD card setup.

IMHO, Horizon's CS including both the Spektrum and JR radios, is among the best you'll find in the hobby industry or any industry I've dealt with.

Now I'll suggest you do something I see too often ignored when considering a new radio. Go hold the radios you think you're interested in, you may find that you just hate the way one feels where another might feel just right with the others somewhere in the middle. I want a radio to feel right in my hands....
