FrSky D8R-II PLUS 2.4Ghz 8CH Receiver with Telemetery
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 (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).

Hi! Please did this receiver have the RSSI output???
I need to use it with my eagle tree OSD, so I need to know if is possible to get the RSSI output from this receiver and how to connect it to my Eagle Tree OSD.
This version doesn't have an analog RSSI output for your OSD. You need the "D8R-XP" version. I have one of those and it looks to be exactly the same thing with different firmware loaded and a different label attached. You may be able to re-flash yours with the D8R-XP firmware to get CPPM and RSSI functionality but I'm not certain about that. You may brick your receiver.
I searched the web a bit and found that you can load the D8R-XP firmware on the D8R-II Plus and get that functionality. The D8R-XP outputs a PWM signal for RSSI, not an analog voltage so you need a 50Hz filter connected to use its output for RSSI on your OSD Pro. I personally gave up on trying to use this stuff for long-range FPV and went with Dragonlink instead.
Every slot can be powered because they are bridged. SO you pick it i prefer number 8 if it is not powered by the esc. By the esc you better put it ot slot 3. Actually on every rx the slots goes like that 1-2-3-4-%5 or RETA. www.link Hope that helps. Best answer helps also. :)
Hello , any body there . Here I lost them two little antennas from a crash ,What type of wire can i replace with, or is there a way i can them antennas .no i,m not gone through the receiver out , just for antennas . Thanks for any suggestion.
Bind one receiver with your TX, then switch it of. Then bind the other one with same receiver. Now you have two rx linked to your tx and working identically. You can now use a buddybox to have redundancy. Thats it.
Adding to Skyfox60 .Your two receiver should be identical same as above .Note your module should be frsky telmet as well .By the way you dont have to have expen boddybox if you run each receiver for half of your plane,means one for right hand and one for left hand of you plane .I used to fly 200 cc with two recievers no buddybox A ok .Note power each receiver with seprat batt ,you need at list 2 pack of 4000 mAP lipo .But i advice you to go with frsky HV receivers and HV servos to be on safe side ,go on you tube and get some infos ,200 cc motors are serious business ,be safe .
Look at back of your frsky module there are two micro small switches below binding switche they can be change to go telmet or non temt , if your module doesnt have those micro switches ,then your module is non telmet and wont work with this receiver .Look above for sepc it says which module.
with this receiver having the 2 antenna what is the best way to put the unit in the model to get the best signal and range? with both antenna flat? with them at 90 degrees to each other? or with an extension put them along each wing?
There are two ponints of view to regard. With the antennas located at an angle of 90°* you will have the best chance to get a signal usingg antennas diverity. With one antenna shadowed out, the other one will receive and the receiver automatically takes the best received signal. Thats for safety reasons, not for range reasons. For ragne enhancement, best way is to put antenna in same direction as TX antenna. Lets say vertical. further more you have to regard you tx antennas shape of RF-field. A straight antenna has a shape that is a circle, around your tx antenna. Field is worse in the direction your antenna shows and is best sidewise. If yo now put onereceiver antenna vertical at the left side of your plane and one at the right side, your diversity is shaped like the field of your TX antenna. Thats the way for best range. I prfer the 90! shaping, giving me more safety instead of more range, because the range noemally is enough anyway. The best range design is to prefer for FPV flying. Therefore, as said, the antennas should parallel to the TX antenna.
ok dumb question on binding.
Manual saying to turn on receiver while holding on to button ok. but wher do i put the battery? i have 7.4 do i have to set it up with esc motor servos? can i just plug a 7.4 and a servo?
Hi! i would like to see voltage of the battery in my plane, do i need anything else (display, i know, but something else) to know the voltage? some systems need extra sensor, some doesnt, and i dont know if this need it or not. thank you
if you have this receiver and the FrSky telemetry module, you still need to get a display and sensor to get voltage informations! Without display and sensor, the only thing you will get are beeps from the Transmitter (Tx) module when your radio signal (RSSI) gets low. I use the FrSky DHT-U display, that connect to the back of the Tx module and shows you RSSI signal as well as other data. If you want the voltage, you need voltage sensors. For that, you can use either the analog sensor sku FBVS01 (2.8$, cheap!) that connect to one of the two analog inouts on the side of this receiver, or you can use the FLVS-01 sensor and connect it to the digital input of the Rx, via the FSH-01 hub or the FAS-100 amp sensor. I use both solutions in differnent models. The cheap analog sensors work OK, but is less accurate. Sorry if this sound confusing! Anyway, bottom line is : if you want to SEE the voltage, you need to get a display and a sensor.
The 3GX control unit replaces the mother Spektrum/JR receiver (eg. AR7000 etc) and works with one or two spektrum/JR/HKOrange DSM2 sattelites that are bound by a conventional bind process. Just pretend its a receiver (needs at least one of the sattelites bound to function at all including during setup) and use the bind port on the end of the unit. It does have compatibility with Fut Sbus, but don't know about FrSky on your radio. I don't know if it will function with another receiver setup like 3G does.

As I have stated earlier, I wasn't the one who brought up credit. Nikos did when he accused me of not giving it, as apparently he needs his 10 cents really badly. I have been nothing but polite and thankful, but my patience with this Nikos chap is wearing thin. It seems as if he is preaching one thing and practicing another. To repeat, I never asked for help by offering credit. I simply and politely asked my question, to which Nikos replied by saying "give best credit, you don't pay anything"
He then unfairly accused me of a bad attitude, trying to put me on the defensive. It seems he is nothing more than an Internet troll, bent on discrediting me. He clearly showed he was in it for the credit, and then tried to back out saying he was in it to help the hobby grow. Please, I implore you, read the previous comments and you can see how it all transpired, and how I have been courteous and patient.
Nikos, I'm going to have to respectfully ask that you stop accusing me of having a bad attitude. Based off of your typing, it looks like English is a second language to you, which is fine, but please make sure you understand someone before you make such an accusation. Often it is hard to accurately judge someones attitude through what he types. I said I would award credit once my question was answered. Why would I award it before it was answered? If I did that, people would assume it was answered and not respond with the information I was looking for. You clearly didn't want me to give credit to "get me in the spirit", you stated the money aspect by saying "I don't pay anything". I am more than happy to give credit where credit is due, but to award credit before the question has been answered would be counterintuitive. Tracar and Laxmikant gave detailed, descriptive answers, which I very much appreciated. Now I know what to buy. Thank you
Not a polite way to request help by offering credit.
I personally couldn't give two hoots about the measly credit. It does show a persons personality and mentality by their approach. This forum is to help others, you need not offer incentives or bribe,just politeness and common courtesy and you'll be just fine.
Thanks guys. My goal was to buy the proper parts for the specific telemetry/Tx setup I want. Nikos, I'm new here and had no idea what the importance of credit was. Without even giving me time to give credit you were on my case for not giving it, and the way you worded your response sounded like you were accusing me of getting something for free. I truly appreciate the people who gave helpful, descriptive answers, as they will help me in my purchases, and help this hobby grow with a positive attitude amongst positive minded people.
here we help each other not for the 10cents. If we know we help. The "thank you" is the best answer. I didnt ask you to give me the best anser i told you to credit the best answer so that you get the spirit. No need of credits. Give it away o everybody else. We are polite in here mostly.
Bad manners friend or Bad attitude will give you No aswers. I hope you get the point. Have a nice day
i have the FrSky PLUS 2.4Ghz 8CH Receiver with Telemetry
the FrSky DHT 8ch DIY Telemetry Compatible Transmitter Module
and the FrSky DHT-U Telemetry System
**the D8R-II and the dht-u work well together without opening your radio and saudering stuff, the dht-u needs to be plugged into where your stock tx module is on the back of your 9x to 3 of the pins ( ) ( - ) and ( ppm ) ..
The FrSky DHT 8ch DIY Telemetry Compatible Transmitter and the d8r-II works well too but you will need to do alot of hardware modding (saudering) for this to work. there is even er9x firmware to support this type of mod and display telemetry in the 9x radios lcd screen
I'll credit best answer when my question is answered. I want to know what the difference between these two products is, and I want to know what is the point of having telemetry capability in both the Rx and the Tx module. Do I need both for telemetry to work, or just the Rx?

So if this module (FrSky DJT 2.4Ghz Combo Pack for JR w/ Telemetry Module) is used with the FrSky D8R-II PLUS, can I see telemetry on my 9X radio screen? If not, whats the point of having a module with telemetry capability?
If you fly FPV, the audible RSSI alert for signal strength is worth it alone. Use the other channels for receiver voltage, main battery pack voltage, your choice... plus one RS232/serial port for realtime downlink to transmitter. Fantastic!

These are just fabulous receivers. Tested my first one out on my Eflight Extra and got a few low signal beeps at the extreme far corners. Landed, rearranged the two antennas, and presto the problem solved. Also tested with several low state receiver batteries and it didn't hesitate to bitch. All this with no programming. I now own 8 of these little guys and real happy with all of them.
