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!
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 (ACCSTis 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).
I have this in my 9X and its working great. Question is, can I also use the OrangeRX dsm2 (forexample) plugged into the back of the 9X? If it matters, I bought the 9X that came without any module. Does the FrSky have to be disabled or the toggle switch set to a specific position for it to work?
You can use both at the same time. It might be usefull to have only one switched on at the same time so your transmitter battery lasts longer. Also, if you have both modules switched on you need to have two antennas sticking out of your transmitter. Never turn on a transmitter module without the antenna screwed on else the module will burn.
I'm trying to bind this module with D8R-II Plus receiver, but the module doesn't switch to the bind mode. As soon as i power the radio (Futaba 9C), the moule gets into the range check mode and stays there...
Does anyone have a similar problem?
Have you checked you are in PPM & not PCM mode?
Have you tried pressing the range check button to see if it goes back into full range mode?
If yes to both might be worth a visit to the FrSky online support page. They tend to respond within 48 hours.
Sets the transmitter in one of three modes: 1 way - for non telemetry receivers, 2 way - for telemetry ready receivers, and FW for firmware upgrade mode.
1-WAY Compatible with non-telemetry receivers:
2-WAY Compatible with telemetry receivers:
FW Firmware Upgrade
The worst part about this is ordering it and waiting 30 days for product to arrive. The best part is that everything you order no one can seem to find the order after that. Sing Post no help, HK no help till 39 days, and USPS no help. HK fix yer shipping problems. been since 28th of march when it was shipped from china, now its the 23rd april noone has seen it.
I also had to wait a long time to receive a Singpost package.
Singpost packages may take up to 45 days to arrive, and unfortunately they use a lot of that time. Tracking updates come very slow too. I asked support why my package was sent with Singpost. They said because there's a LiPo in it. Without lipo it ships with HongkongPost, which is much faster. Now I order my lipos in local warehouses.
I received the package today!! Perhaps I should learn more patience. I appreciate and understand your plight Wout, it becomes very frustrating with no word on anything. I have been ordering everything I can in the local, we'll see how it goes. Thanks for telling me about your story, hopefully HK will work on getting more supply to the different regions to facilitate shipping faster.
Hi. What main different between this one transmitter and PRODUCT ID: DJT ? I want install it to my turnigy 9x. Is it possibile somehow to do that telemetry information would be availiable on my turnigy 9x screen with this transmitter and PRODUCT ID: D6FR receiver.
The main difference: the DHT module here is for self soldering, sticking and drilling into your transmitter by yourself. The DJT module is ready to plug it into your 9X, but you have then a second antenna at the bottom (or back side) of your 9X. The D6FR supports telemetry and is able to communicate with the DHT and DJT module, but you have in both cases to modify or to connect the DHT or DJT module with the controller of your 9X and to flash a new software into it for the communication between the 9X and FrSky module and the ability of the 9X to display the telemetry data. The software is named 'er9x'. You find it on google code. There are some good tutorials in the web about all these modifications and the installation of the DHT here into the 9X. If you are good skilled in tinkering electronics: take the DHT module here, otherwise take the DJT. Have fun wit it!
I wrote about my job installing the module on my MX-16 radio. It's something that can be easily "adapted" to the majority of PPM radios. You can check it here:
I have installed 8-10 of FrSky DIY Tx modules. Three of which are the telemetry type. The last one I completed (yesterday) works fine with Telemetry as well as non-telemetry receivers EXCEPT. After binding the Tx to the Rx when I power up the Tx and then the Rx the Tx module "beeps" at about one second intervals when the rx is powered up. If I should turn the RX off the Tx module continues to "beep".If I turn the Tx off and then back on it does not "beep" until I power up the Rx again. I have a screen on the TX but as best as I can determine there are NO alarms loaded into the system. Does anyone have a clue as to what's wrong? Any help shall be appreciated! Thanks...Tom
I contacted Hobby King and FrSky direct about the problem above.. I got no satisfactory solution from either. I replaced the DHT module and every thing works as it should. Obviously the problem was caused by a defective module. This exercise cost me in both money and time. I removed the heat shrink covering in an effort to make the DIY module to fit in side the Airtronics module case so I can't return it for a replacement or credit. This is a real unfortunate circumstance........Tom
I'm not sure if this is your exact problem but I had the same thing happen to my hitec flash 5x with the older model v8ht frsky hack module, easy fix, you need to install a capacitor in line with the lead, I forget the value, small, look it up.
Does this transmitter modul beep when rssi is low with the V8FR-II receiver? (i know it's not a telemetry receiver, but maybe can send rssi signal?)
Also, why are the antennas on the receiver sooo long? Before i had KDS 2.4GHz receiver, also with good range, but with only 2 small antennas on it (3-4cm). Is it long because for plane usage? I use it with multicopter, maybe i can cut off a little? Or it will decrease the range? thx!
Regarding long antennas:
DO NOT JUST CUT what you called ANTENNAS OFF! FrSky reciever has two coaxial wires plugged into it. At the end of them there is a portion without the outer insulation and shilding. This section is the same length as other shorter antennas.
You have several options:
1. just spread the wires and position them orthogonally to enjoy nice diversity
2. buy on of "FrSky Receiver antenna"s that are avialible on Hobbuking
3. cut both the wire and shilding by the same length and leave the same length of stripped wire.
Hope it helps.
Andras, I can not comment on beeping as I do not have this TX module but only own a stand-alone one. My guess here is NO based on the fact thea on a separate module only if you connedt an external display and set it up it beeps.
Can someone PLEEEASE help me I have been trying and trying to connect my new "FrSky DHT 8ch DIY TX Module" to upgrade this transmitter from 72 mhz to 2.4 Ghz. I have enclosed pics of what the inside of this transmitter looks like and I would just like to know where I would connect the 3 leads (RED = V BLACK = GND & YELLOW = PPM)
Please email me at davidwozniakbsn*gmail****
I did! but the 1 I have is the telemetry 1! at the back of the sd-10g , there is a S-video plug! at the upper right is the ppm8 singal ,than all u need is the power for the module! I didn't put the module inside . I just make a box hange it outside when I need it! box s-video plug(male)
Ok so if anyone wishes to purchase this module and NOT wish to use it for telemetry but rather ACCST connection, then installation videos seem to imply that NO firmware upgrade is required.
Can anyone verify this?
You won't need to do any firmware upgrade, you can even install this inside the OEM 9x Module, and keep the radio 100% stock. Even if you want telemetry you can leave the inside of the 9x stock, this PRODUCT ID: FLD-02, connects to the DIY module. you'll have to start using Frsky receivers after the DIY install, i assume you already know that
Bruce at RCmodelreviews on youtube has an excellent tutorial based on the older version of this... the only difference is the switch, which I mounted on the top of the radio, left of the pot. Clearance is tight so ensure you drill accordingly. The bind and LED are mounted just in front of the antenna... Keep in mind that that the LED might not be soldered square in relation to the board it sits on, so I desoldered mine first to straighten it up then resoldered it back to the board. The reason I did this was to ensure when I drilled the 3.0mm and 3.5mm holes it was a perfect fit. I will post some pictures in the files tab this evening to show how it looks.
Has anyone managed to get this working on an AM radio?
I know the old version was successfully converted but haven't seen anyone do one with this module.
I'm looking to convert a custom radio which uses Futaba FP-T4NBL 29mhz AM internals.
There is a way to make a trainer port in this Tx but I don't know if the signal is actually PPM or some other raw signal. www.link is the info how to get the trainer port out but I'd suggest contacting the author what's the signal like.
I asked my self wich i buy or Modul futaba od DIY modul.. i have futaba C9 and I already have an DIY modul build in but it gous out... is any difrence brtwen Modul type and DIY type.. i need apinion
I have both. I like the module with the case better. win I have it in my transmitter glove, you have less change of hitting the two-way switch. And you don't have to open the case to reprogram or update. Just plug and play.

I instaled this module in my futaba fx-18 easy as a pie.Cut power wires to old 35mhz part use those wires for powering DHT module,solder yellow wire to ppm signal in the back of trainer plug.I unpluged toggle switch(now it is impossible to make a mistake or bump this switch when in air with model) default setting is 2-way mode. when needed for fw upgrade i can plug it back and remove after.

I Installed it in my Graupner FM314 and it works fabulous!
Even without TX antenna the signal is strong enough to span 10 m and more.
Thats enough for my truck.
The only bad thing is, that I cannot use two D8R receivers at the same time at one TX. Previously I used two RX. One in truck and one in trailer.
Does anybody know, if this works with the V8 receivers?

I just received the DHT Module and a 8 channel receiver. Installed in a Futaba T6XAS today and it is working fine no problems installing. I mounted the switches and bind button on the back side just above the trainer plug outlet. The main module was mounted against the CPU on the Futaba using double sided foam tape. The antenna was mounted in place of the 72MHz one. Binding was great no problems binding to the transmitter. I checked all six channels and all are working with no jittering noticed. I will try a range check tomorrow and maybe fly in a plane on Sunday.
Installed at FUTABA T6XAS.The telemetry is a good auxiliar tool to fly with thermal planes when you go far away from you. The beeps from RSSI alarm advise you of the condition of RF Link.
