Hi everyone, I have been out of Radio controlled flying for a few years. I decided to dust of my Raptor 90 and go fly it again. One Problem is I sold my radio gear. I have noticed things have moved on quite a lot since I last flew. I mean 2.4 ghz radios were just a rumour when I last flew.

My raptor has a Futaba 601 gyro and a GV1 Governor. What are the pros and cons of the Futaba 8FG and Spektrum DX8 and whether they will be ok with the current equipment.

Thanks

Servos don't matter much anymore, they should work with either radio. You might want to upgrade to digital servos for the newer systems.

Both are great radios.

8FG: The timer is hard to hear on the 8FG and it wont work with with micros that use spektrum receivers. The gimbals are great. If you are going to fly complicated planes it would be nice to have the extra channels. And it works with the CGY-750 flybarless unit.

DX8: Has nice features like telemetry. Works with lots of different models including micros. Very easy to use and program. The timer will vibrate as well as beep and it is loud. Its only 8 channel so I guess that could rule out some large planes not that it would matter to me.

You can't go wrong either way.

IT's what I do.

Your servos and other electronics will be happy either way.

As for the remainder of this thread, you'll get a lot of pros/cons for both radios. Perhaps some heated discussion, too.

Either one is a great radio. Pick what you wish and enjoy it.

Don't overlook the JR 9503 and 11X and the Airtronics stuff either.

Both systems are very good. The 8FG is a 14 channel radio, the DX8 is only 8. Futaba uses S-Bus receivers now which gives you multiple choices of connecting devices to the RX. S-Bus is serial bus and can transmit all channels over a single servo type connector to connect FBL units , gyros, and even S-Bus servos. You still get standard servo type connector on the S-Bus RX too. You can mix connection types (S-Bus and Standard) if you want/need to.

Spektrum uses a new codec called DSMX that is more relaible in ciongested environments than the older DSM and DSM2 codecs. DSMX is backward compatible with the older DSM2 format. Spektrum vibrating timer is a nice feature in a noisy environment. The Spektrum telemtry is a really cool feature. No need to time electric aircraft anymnore. Just land when the buzzer goes off indicating a low battery voltage. The Futaba is supposed to be getting telemetry as a firmware upgrade with some new hardware required soon.

Both have bearing supported Gimbals. Can't go wrong with either system. You might as well look into the JR 11X and ATX offerings too as dkshema mentioned.

No comparison
IMO, I don't know how you can compare the 8FG with the DX8.

The 8FG is more comparable to a twelve channel radio like the 12FG. Just, read through the owners manuals for both radios and you will see what I mean. The 8FG is totally programable, It is not a matter of, "can I do that?" It is a matter of, "how do I do that?"

The downside to the 8FG is that the manual is thin, to say the least. And it is so programable that you have to learn to program it. It is defiantly not, plug-and-play.

The downside to the DX8 is that it is spectrum programing. Spectrum is new at programming. Go to you tube and you can see all of their programing wonders......on video?

The upside is that it will work with all of the BNF aircraft, a park flyers dream.

I went from a JR9303 to a Futaba 8FG. I have more channels, more built in features, more functions and more programability. I have stepped up, not down. I went from nine channel radio that was easy to use to a full featured 14 channel radio that is fully programable.

Don't let the eight in "8FG" fool you. It is not an 8 channel radio, it is a fourteen channel radio with an 8 channel size screen.

There is no comparison.

8FG- good solid radio, can be confusing, I hate the interface(ipod type). Takes a little while to get use the programing. Can do lots of mixing with the extra channels.

DX8-easy to use out of the box. Limited to 8 channels. Telemetry in my opinion is over kill.

The receivers today can be used with any servos.

Damn that ground is hard! When's the right time to get out of this money sucking hobby?

Don't forget to pick them up and hold them. I was tempted to switch from DX8 to 8FG (DX8 had many birth defects) but I fly pinch and couldn't fit my fingers between the switches on top of the 8FG.

It takes away from program flexibility if you must position many of the switches in a way that you can get your fingers in there.

oops, bounced it!

Subscribed. I'm trying to decide between the two as well. I have a dx7 right now and love using the spectrum ar7100r because the rev limiter. But it is a pain to set up the mixes which I hear is much easier to program in the dx8.

Food for thought
Just because you have a DSMX Rx and Tx does not mean that it will bind in DSMX. (i.e. some flybarless systems bind in DSM2)

I also went from a 9303 to an 8FG. I didn't plan to but the 8FG is just so damn good I went ahead. Also, I wanted to use it with the CGY750 (which, IMHO, is the hands-down best FBL system on the market today).

I don't need telemetry. I could use it, it can be nice but it's not a deciding factor for me.

The 8FG has a spotless reliability record, which is really not the case with the DX8. DX8 has been upgraded but I just trust Futaba QA more. Note that I'm not aware of any current issues with the DX8 but I do question Spektrum's QA at this point.

FHSS (Futaba) is proven at this point, DSMX not so much (still very new).

The 8FG has amazing programming features. It's not very straightforward though, and some stuff might take a while to program because it's just so damn elaborate (dual rates pop to mind, you adjust them for each flight mode and it can take a while but worth it).

I did like the layout of my 9303 a bit more, and I also don't care for the 8FG case materials (it's pretty plasticky). If Futaba updated their 12FG to have 8FG features (backlight, CGY750 support, etc) then I'd be all over it as it's a great feeling radio.

I'd say this: If you're a more casual modeler who flies micros or generally inexpensive stuff, go with the DX8. It's friendly, and model match is gold. It's a lifesaver.

If you go with more expensive models where reliability is THE primary concern, or if you fly planks which Futaba does very well (progamming and SBUS) and might need the full 14 channels, or that you want to use CGY750 or any other form of SBUS, go with the 8FG. Lack of model match sucks but Futaba countered this pretty well with the new startup menu (you have to select the model on startup, has shortcuts so it's very good).

For me the choice was the 8FG. Love it.

The 8FG is a very capable radio. You'll be amazed at how flexible this S.Bus stuff is once you try it. I was skeptical at first but now I love it.

The "ipod" style wheel on the 8FG does take a bit of getting used to. The first day I had mine, I went on HeliFreak and watched Mercurial's 8FG video and practiced with the 8FG in hand. Within an hour I was used to it and was comfortable navigating through all menus. Now it's a second nature.

If you need more space between the switches on your 8Fg, swap the switch nuts out with the ones on your Real Flight Interlink controller. It makes a WORLD of difference!

+1

Either choice you'll have a great radio. Not sure about the DX8 but the 8fg is easily updated. Like any radio. It takes a little playing around time to get use to everything. I love the ipod style wheel of the 8fg. Once I got use to navigating around the menu {within 60 minutes} its a breeze.
Another + for me is Futaba's gimbals. I like the feel better than JR and they seemingly can be adjusted lower. Maybe I'm imagining it cuz I've never measured the two. I set em as low as they can go and Futaba wins for comfortability in my hands.
Also using the 8fg super with the Futaba CGY750 fbl system makes my heli like I'm flying in a dream.
The two compliment each other so much they were meant to be.

8Fg is an awesome radio but it is needlessly complicated to program. That's Futaba though. It just works, after untold hours of clawing your own eyes out wondering why on earth they would make programming so convoluted and non intuitive. I blame the manual though, it gives you just enough information to be dangerous. Once you learn how to program the radio it really is a fantastic radio.

Downsides for me is despite the nice gimbals it feels like a cheap radio and the display is small and cluttered. If you can get past that it is, to me, the last radio the average user would need. There is probably more programming than the average person actually needs or would use but if you can get it, why not?

I'm a JR based Spektrum user by the way, I use the tried and trusty JR 9303. If I had a driving need to replace all my radio gear I would probably go either JR 11X or the Futaba 8FG (I like the S-bus system). I won't use a DX8 because I don't trust Spektrum radios. I prefer JR radios that just so happen to transmit using Spektrum tech. A lot less problems.
