FrSKY ACCST technology is proven, approved by many model associations, tested and reviewed as the leading Chinese 2.4Ghz R/C Technology. If you think DSM2 or FASST is the best, think again!
New FrSKY ACCST (Advanced Continuous Channel Shifting Technology) gives you secure radio communicatios in 2.4Ghz band. ACCST 2.4GHz system shifts 80 channels around hundred times per second in the 2.4GHz band. This means that the system is completely resistant to interference in that band.
The Two-way Radio System developed by FrSky provides an additional return link that would be used for monitoring the Rx’s voltage, temperature, location, speed and so on.
Features: Advanced Continuous Channel Shifting Technology (ACCST is our advanced tecnology it shifts channel hundred times per second and there is no signal conflicts and interruptions) robust frequency agility. Easy to bind and very fast link-up. Excellent reboot time. True Diversity with two antennas. All channels can be programmed with Failsafe, quickly and easily. Quick and extremely stable in performance. Precise and smooth servo response. Extended range (1.5km-2.5km).
Receiver Specification: Operating voltage: 3.5 - 10.0V Power consumption: 100mA Resolution: 3072 Latency: 22ms Analog voltage: 0~3.3V Number of channels: 8 Range: 1.5km-2.5km Dimensions: 55 x 25 x 14 mm Weight: 12.4g Version: 2.0
It will work, some modding is required though. First, the module itself won't fit snuggly in the tx module bay, you will need to cut out or widen the holes for the pins to make contact. to get telemetry readings, you will need the to perform the frsky telemetry mod and flash your 9x with er9x - frsky firmware. Without the mod, the only telemetry available for you is the beep sounds to indicate signal strength. There is also the option of frsky telemetry display. Just search for frsky telemetry.
Depends what do you want to achieve. If your intention is to have telemetry on the external display, no mod is necessary - simply swap stock Turningy transmitter into DJT. Mind that to fully use this featurre you need an external display - FLD-02 (it is connected to the DJT transmitter at the back). No soldering is required in this solution. To display telemetry on the main LCD of the 9x, a mode is needed as mentioned by Roger but that requires some skills on soldering. I'm using external (secon display) attached at the top of the 9x box and it performs well. Swap takes about 5minutes then, and FLD-02 is not very expensive, anyway.
Basically, it means remote measurement of something, be it voltage, temperature, altitude, speed and many more. You,'ll be able to receive readings from different sensors connected to the receiver or the sensor hub.
HK forgot to tell you that you don't actually need anything to be really happy. If you want to fly anyway order this set straight away becaus it is sold out all the time. Both TX modul and RX due support telemetry, all you then need is the hub and anykind of sensor. To display the data you need the little screen as well. But as I said it is a neverending buying story.
Hi All, can someone tell me the difference.

I don't know what i need :) I have turnigy 9x transmitter.

listen tox-is: V8FR-II RX is not telemetry capable - there is no plug for the sensor hub and there is no "telemetry" written on the case (it is a smaller rx), but D8R-II PLUS is for telemetry because there is an extra plug for the sensor hub and it is also written on the label of the box. Both will work with the tx module but only one will be able to send data back to the tx. HK is just trying to get rid of some old ****, they couldn't sell it anymore if they would explain it clearly. Have a nice day.
Hello Peierre Thomas,
this module has a PPM input pin and also the receiver is unsderstanding ppm onl. We are missing one channel ( 8 on ppm, 9 on pcm ) but from technical point of view it is not necessary to have pcm when using 2,4GHz. The modulation is.., let say ,.. some kind of pcm. that makes it safer than older ppm signals transmittet by AM or FM . That was btw the reason to develope pcm transmitters in earlier days to make transmission safer. So you can live with your 8 channels, than try it out. This FrSky module ist really very good in function as well as in range. ACCST is one of the best TX-principles you can buy. It is as safe as fasst or hott. I like it and it works as good as my futaba tx which I use also with receivers from FrSky.
Hey, nope, you can't use PCM with this one. It specifically says in the manual that you must be in PPM. Unless you need the channels, you will not need PCM for range, this is the best long range setup for price and capacity.I don't actually know anyone using 9 channels, and very few using 8. Me, I typically use 6 or less, but I can see running an FPV gimbal taking me to 8.
You can use the module with the existing firmware...no need to flash the tx.
As for range, that's a tough one...if you were experiencing shortened range with the 9x radio due to interference, the module will help since it employs channel switching which is less susceptible to interference from other sources
Correct. The FrSky module will work with the FrSky compatible receivers and the 9x mod will continue to work with the 9x receivers but you need to mod the antenna...I ordered a RP-SMA (Reverse polarity sma connector - a connector compatible with the FrSky antenna) from DigiKey and mounted it on the back of my stock module...now I can still use my old modules if I plug the old module into the tx
I don't know about perfect... First, you have to remove the module from the 9x, and transfer the antenna to the old module (if you want to use it again). Maybe Nikoiaos has done this already, but I haven't, check to see if it will work with the 9x stock firmware. I have heard (unconfirmed) that it won't, and that you will need to flash your TX with ER9x, again, I don't know, but you should be ready for that. The module does not fit the 9x completely, so you will have to trim some plastic (that has been confirmed), after that, you are 100% ready to go!
Hi, im new to all this. my question is, where is the telemetry displayed? I use turnigy 9x and fatshark predator v2. Do i need anything else to connect this together? The more i learn, the more confused im getting.. Thank you in advance :)
This telemetry is no good for use with your fatsharks because you can't read it!!!!
You need an OSD like the tiny OSD, a small board that sits in your model and displays telemetry on the image in your goggles.
anyone know the wiring for this and the Multiwii Pro? I'm having a beast of a time getting this wired up correctly. The radio is bound to the FySky receiver, and I can control the motors, if the speed controller is connected directly to the receiver instead of the Multiwii board. - Thanks in advance
thanks for the info, but I'm looking for wiring, literally, "wire 1 goes to ..., or red wire goes to..." this is for a quad copter setup. When I connect the board to my Galaxy Note 2 using MultiWii GUI, the sticks work, altitude, ect.. all work, but anything related to motors doesn't work. If I connect a speed controller directly to the FrSky, the motor works via the radio (9XR), but the motor doesn't work if plugging into the multiwii pro board.. I'm stuck..
This item (PRODUCT ID: DJT) has telemetry capable module and receiver (D8R-II Plus). While with the JR-Combo ($36) you get the same module and a V8FR-II (HV Version) receiver which is not telemetry capable. If you want to have telemetry, get this.
Thank you for the fast reply!
I found this mod.*******forum.turnigy9xr****/converting-9xr-to-fr sky-telemetry-djt-module-t362.html
Ive got one more question. What cable do I need to flash the 9XR?
Thank you in advance!
Yes. First, you need to flash your 9x with ER9x, or Open9x, next, there is a mod for doing the telemetry data on the 9x screen, but if you think about it, do ou really want to look down to check your telemetry data? Anyway, happy flying!
Danieli Effina was not reading wright. No you dont need to mod to use it in 9XR!!!
Allthough you cannot display the data in 9XR without mod. But you have the option to buy the FLD-02 FrSKy display to see the telemetry data.
Hope that helps, like the best answer :)
The telemetry itself works with any Tx. But to read the telemetry values, you need to make an internal modification and upload an er9x firmware for telemetry. Second solution is to put the FL02 screen out of your Tx.
could you tell me what the difference between the receiver of this combo and the receiver of that combo
(http://www.hobbyking.com/hobbyking/store/__14 349__FrSky_DJT_2_4Ghz_Combo_Pack_for_JR_w_Telemetry_ Module_V8FR_II_RX.html#relprodspan_focus) is?
Fighter Command, I saw your video and I was curious. Did you really only get 704m LOS max range with the Frsky Telemetry module? or is that just how far you flew before turning back home. 700m seems like a low range to have compared to the 1500 m range everybody's been claiming especially given that you were in such an open field during your flight.
A great view!! :) I have attached to my TX a FrSky FLD-02 Telemetry Display Screen using the FrSky variometer and gps you get a very accurate display. I have no signal lose as I am fly at that altitude. Images are from a wing mounted hobbyking camera. It is all LOS at the moment, just so impressed with this equipment..
I still don't know the answer to my question. Does the FrSky Telemetry system transmit this video image from the wing camera to the FLD-02 Telemetry Display Screen ? If so then I'm impressed. If not then I don't know what this video is demonstrating ? I don't see any telemetry displayed.
Shipping time is not only possible, it happens all the time, unless you travel to Hong Kong and collect your order yourself, then it takes travel time. If not, they ship, and that takes shipping time.
Hope that was a helpfull information for you.
My stuff takes to germany min. 8 weeks. 3 to 4 days to ship, order is now on the way to germany. That takes 11 days mostly. Bur then, waiting begins. It takes another 3 Weeks until parcel is out of the customs. At this point I have to wait another 2 weeks until it arrives the local customs office.
So 8 weeks is not a problem to reach. It´*s bte. to order now for next christmas. But it is not HK who takes that time, it is airtransport and csustoms procedures.
But, on the other side, this FrSky stuff is worth to wait for. Mine is working perfectly. Good range. Perfect operation. Telemetry works fine. Ther is only one thig FrSky should develope. The telemetry data should be set over to audio out with earphone.
That would be grat because when I am very high with my glider or fly a heli, I cannot look to the display. To dangerous not to see model early enough if eyes are away from it. A small box connected to the TX-module that has no display but buttons to have each data in sequenz, vario and altitude permanent, or single data selected an spoken every few seconds. That´*s it I think.
Should we write a letter to FrSky. Oh, I forgot, it should be compatible to existin TX modules :-))
Yes, that is fine. What, if FrSky produces some different interfaces to have telemetry either on separate screen( they have that at the moment ) or on audio or as a OSD for FPV video data, which has to be one for inside the aircraft.That would come to be the burner of the year, and btw. that is not that difficult to realize. For on screen display, they only have to develop a decoder that takes data directly from sensor hub. I know the voices in my brain are not real, but they have so kinkiii ideas :-)))
to make it fit you will need to take of some of the PLASTIK HUMP INSIDE the Module BAY of the Turnigy 9X.
Best way to do th is without harming the Pins is to take the Case apart (6 or 8 Screws) take Backcover off. Then remove the PCB Inside the Backcover (which has the Pins on it)and then use a Dremel or file and remove about 50% of the Height of the Platic.
Remount the PCB and Backcover and you be able to use the Module in your 9X.
Hope this helps you ... if it does, please feel free to let me be credited by clicking on the best Answer Button below.
Wolfes is spot on with his answer. Wish i had thought about the removing of the pins before I had at it with a dremel. After an exhaustive 2 hour power tool surgery the end result is the same, just wish i had known about the better route.
Yes it includes telemetry transmission. But if you want to see values, you need the separate gauges to be connected to the Rx or to the hub if you want more than two values and also you need the screen from FrSky to display those values and set alarms.
Yes, by purchasing this combo you will be able to conduct range checks using the module and the D8R-II. If you purchase other frsky sensors (Variometer, temp probe, gps, volt meter, ammeter) you will need to also purchase a telemetry hub FSH-01 to connect them to and a display FLD-02 or DHT-U.
Yes, there are dummies out there using these things very badly and unsafely. On the verge of being banned are harsh words, and there are some ignorant people that don't understand the people are screwing up, not the devices. My use for this is commercial, as soon as it becomes legal to do so. There are a lot of people who are working to prevent stupid legislation from stifling technology.
I would agree* "banned" may a bit much. Unfortunately, FPV's have made national notoriety being on the national news a few weeks back. You know how the media can blow things up. LRS and UHF set ups being used w no licensing, flying too close to airports, etc. It only takes 1 to mess it all up for the rest of us.
That is why it is up to us to educate people on the benefits of this technology. Next Thursday, I am doing a seminar on drone technology at the Anderson County Regional Airport, and I will be taking questions afterward. I am recording it for YouTube. You can do things like this too, as Nike said "Just Do It"!!!!
I 100% appreciate this subject being brought up. We need this discussion. Me, I want to fly FPV over Lake Hartwell, take videos of people recreation fishing, and sell them as DVD's to these people that love boating and fishing. Talk about a fun time video! Of course, still photos as well.
My gaol is to use FVP to fly over the Australian countryside. I have enjoyed your conversation and feel we all need to agree to do the right thing and not to risk our sport by doing the wrong thing... Never let the fear of landing stop you from.taking off....
I totally agree Fighter Commander, and for now I am limiting myself to line of sight, and 400 feet in altitude. I am a member of the AMA, and I belong to the Tri County RC club in Anderson SC, Look up Lake Hartwell SC, and you will see MY flying field!!!
Attention de marche pas pour Graupner MX 24 S. Le brochage du module DJT n'est pas prvu pour MS 24 S, diffrent des MX22. Photos d'un module Graupner et FrSky pour www.link va devoir fournir un marteau pour monter le module dans les MX24S 8-(
Be careful not work for Graupner MX 24 S. Watch the pictures.

This is a standout system amongst the Chinese 2.4. More resilient link than DSM2 (Spektrum don't like to hear that) due to the hopping frequency. See http://rcmodelreviews.com/frskyreview.shtml for a review of the non-telemetry system. See www.link for discussion of the Telemetry. Frsky have made the protocol PUBLIC so anyone can design sensors (are you listening Hitec??)
The build quality of this is no where near that of JR, Spektrum or Futaba, but it is adequate. The PCB of the RX was not mounted flat so the servo pins did not fully line up with the hole in the case.
In terms of functions this is perfect, it gains a lock within 1 second, if you switch the tx off and then on, the bind comes back on instantly.
Setting the failsafe position is dead easy, just press the rx button for less than one second.
One thing to note, there is software available to upgrade this to v2, however, the supplied serial cable will only update the tx module. You need to build or buy another interface to upgrade the rx!! For v2 you need to upgrade the tx and rx! so that is a pain!
One other thing, the module can support telemetry and non-telemetry rx. However, to switch over, there is a tiny dip switch on the back of the module. It looks quite flimsy and I'm not sure how long it will last!
Overall, in terms of function this is definitely the 2.4 set to buy. If you consider what you are getting and the fact that it is probably as robust a 2.4 link as the Futaba, add the price of the kit and subsequent rx, you are looking at a major bargain (even with the average build quality).
Build quality not as good as Corona's. To fit module in my Turnigy 9x, needed to bend pins of TX - Corona had a perfect fit. Pins of the RX are not aligned with plastic cover. So much for disadvantages - that is why 1 star is missing. Positive aspects are: 1. Feedback when RSSI gets low, you hear beeping. 2. Range test mode (TX power reduced by 30x). 3. Start-up time below 1 second. 4. Fail-safe, which really works and is easily configured - just one touch of a RX button, or after firmware update, of a TX button! 5. Firmware update possibility - with RS232 (COM) interface. Whole update procedure is described in manuals, and can be easily performed. 6. Smooth response to slow sticks motion. Resolution seems to be really high, although I did not test some excellent servos. 7. Last but not least, telemetry. Out of the box low RSSI or low RX voltage is indicated by beeping, also possible to set alarms for low or high signal on two spare analog voltage ports (0-3.3V)
