hello,  everytime I talk with 'professional', or 'uber experienced' hobbyist about my models and controllers and radio setup, I ALWAYS here a comment or two about my radio...

I have the turnigy 9xr PRO radio...I have never had any other brand... I bought it for the price, and reading sevearl discussions about it on other forums... *(which seem to indicate that the radio is 'better then just ok)

currently, I have my model in a local shop to try to get the pid's dialed in better and to add fpv and the techie really wanted me to switch to a spektrum radio, claiming it was easier, better, longer range... but when I asked a couple questions and got no real answer, I said no... as I didnt want to spend another $200-300 for something that seems to already work...

he really didnt seem to have any experience with my radio... but claimed the spektrum is easier... I am not sure how anyone can claim something is easier when they never tried my radio..

from what I can tell, the JR module system allows me to use different 'frequency'/brands of tx/rx as long as it plugs into the module location..

can anyone answer specifically what other frequency/brands I can be used in my 9xr pro radio? i.e. is there a spektrum type of reciever that can be used in my radio setup?

as far as I can tell the differences include that the 9xr pro has 24 channel capacity, but, getting the sbus to work with naza has been a problem as the radio doesnt have a d16 mode... if I want d16 functions/ability, it has to be done at the 'module level'...and not really in the menu system of the radio itself, (not sure that makes sense?)

before I ramble too much more.. can anyone help me or point me to a resource

That should give you a pretty good idea of what you options are. 

hey, thanks for the reply.  i just saw that video today.. and that does answer a couple questions.. (which I think I knew before and forgot, and hopefully wont this time around).

but, the remaining questions are why is there such a difference in price point and brand loyalty?

why would anyone spend several hundred dollars more to do the same thing...

I could understand if someone needed/wanted more then one 3position switch.. or to have slider switches on the sides or something specific that one brand has that another brand doesnt.

and the guy at the store/shop where my quads are at, isnt really the type to want to sell me something just to make a buck.  he knows i have been loyal to him and have bought a good amount from him and will continue to do so...so, I doubt that he would rock the boat to try to make $20 off the sale of a radio...

anyways...I think another 'difference' that I am dealing with is the D16 mode that frsky uses on the 16 channel sbus setup on the x8r reciever...

the binding procedures need me to set my radio to d16 mode, but the radio does not have that in any setup screen.

so far, I can not get the frsky x8r frsky to work with sbus on the naza lite.. but not sure if that is the specific problem or not.

In general, higher priced transmitters have higher quality switches and gimbals (the stick's mechanism). They also have more advanced features. 

Before writing pages on this, rather look at this video where I think it's explained quite well. 


If you have the Taranis you have everything you need and don't need to buy anything else. If I had a Taranis and a 9XR Pro, I'll give the 9XR to my son and only fly with the Taranis. And If you have a Taranis, you surely don't need a Spectrum. 

I've had spektrum dx6i, dx7s and dx8. The 6 and 7 were great radios that did the job, they are easy to setup regarding dual rates, expos etc but the 8 was a dog. Twice it just stopped sending pwm signals, defaulting to 1500 which resulted in 2 nasty crashes.

I've now switched to a taranis, yes it is a bit trickier setting up everything even with the companion software BUT it is a much more confidence inspiring radio and given it has dx9 features for nearly 1/3 the price it's a no brainer.  

Bill, there are two or three major things involved in radio choice. Basic operational features, both soft and hard, is obviously one, and some inexpensive radios such as the the Taranis and even your Turnigy have a lot of those - and generally the features needed for flying multicopters are not nearly as extensive as for many other aircraft.

Another is the availability of more subtle features, that go deeper into controlling hardware, Things like exotic pre-set mixes, adjustability of servo speed and range, etc. Many of these are not of much concern when piloting most multicopters.

Another is build quality. Why would anyone pay up to tens of thousands of dollars more for certain cars, clothes, watches, etc. when much less expensive versions are available? That gets into a whole new level of choices. You can spend several thousand dollars on some radios, and if you use them to anything approaching their capabilities you will feel differences between them and the cheaper ones in the gimbals, switches, etc. and possibly also in how "locked in" the connection to an aircraft feels. It's the difference between a generic soccer van  and, say, a 500-class BMW. Both will get you down the road, but ...

Personally I spent $1300 on a JR 12X about four years ago, after buying a series of cheaper radios that always ended up lacking one or another thing I needed. I haven't regretted it. But I also have a Taranis for my Pixhawk. Not the easiest radio to learn but vastly capable. I just hope it doesn't fall apart if it takes a knock while I'm flying. 


They're just trying to sell you a radio.

Tell your hobby shop pals that I flew my FrSky-equipped-quad out 2 miles yesterday (a personal best). This was on stock equipment, no special antennas or boosters. I had telemetry telling me my battery and RSSI level the entire trip out. Ask them which Spektrum radio will do that (none) and how much they cost (about 2-4x more).

Spektrum radios are not easier to program than your 9XR, but they are far less versatile. I burnt out several servos using my Spektrum radio when I tried to send the same input to two channels (on servos that were mechanically linked) before I realized that it just couldn't do it. This despite Spektrum's insistence that it was easy to do. It's a 5-second operation on your 9XR.

What I'd love to hear is someone who ran OpenTX and went back to Spektrum. Once you understand the mixer, you realize how great OpenTX is. Hard to imagine anyone going back.

I do like Spektrum for one thing: there are a lot of interesting parts coming out lately that have onboard Spektrum RX's.

To your questions: there are Spektrum-compatible JR modules out there. HobbyKing sells one under the OrangeRX brand.

I have no experience running FrSky w/SBUS.

Can I ask what you're trying to get out of the SBUS setup? FrSky is very easy to set up in CPPM mode, and the Naza M Lite supports it.

It might be that if you ever want to fly commercially and if your authorities care enough the cheaper radios which do not have the appropriate FCC and the like tickets will not be permitted for use. In 2010 I flew at Farnborough airshow and OFCOM the UK FCC would not accept the standard RC permission for my JR radio. I had to ask questions of Japan. All was good once answered but don't expect the cheapest radios to be approved for C2 links.

I'm wanting more channels/functions. The basic aetr then the two or three flight modes, and then I want 2+ extra channels to turn off leds... During the day..

From what I can tell, I can get 7 channels from sbus on 1-8 and then pwm or servo output on 9-16
thanks for the reply. I understand the analogy of cars, and I guess since I haven't got a limit on the Turnigy I dint know. I was just hoping someone could tell or describe an example of a limit that the Turnigy can't handle

Gotcha. I've looked into doing something similar. You have a couple options, but you will need an XJT module. Is that what you are running? Most of us Frsky users run a DJT module on our 9XR's.

Do you only need one output? I can tell you some tricks to get servo output if you only need one or two channels. No XJT needed.

I have both, d and x modules...

One of my problems among the many is, in getting info over load. I'm forgetting more stuff is read more stuff... My head is full which is why I went to the shop.

I have three models each is different flight controller and unique (to me). So I can't keep things straight and have to relearn.

And then I get the shop tech telling me something that seems basic but yet not make sense about the radio.

So I figured I would revisit the radio issue here
