Yep, only the RX units are different between the packages. The TX unit is the same.

You don't lose anything by buying the combo with the telemetry receiver, at least it will warn you (beeping) if you for some reason have range problems or go too far..
I think that little feature worth the extra money you pay for it..

So,to make it clear,the more expensive combo (DF) comes with a telemetry receiver and the module beeps if the plane's gone too far where as the cheaper combo (DJT) comes with the normal receiver which wont make the module beep?and this is the only difference of the two?

And what kind of telemetry can the second combo do?
Can it tell me the Altitude and speed (using the modules directly connected to the receiver) or do I still have to buy the sensor hub for that?

Oh and can I directly get the DHT-U system to get the screen and module inbuilt and connect it to the 9XR directly without any mods?
Like once I know where to plug each of the 3 wires,is that a possible option or I would most likely have to do mods to get the DHT-U system to work?

The D series are duplex ie telemetry receivers, the V8 series are non telemetry hence cheaper.

FrSky DJT 2.4Ghz Combo Pack for JR w/ Telemetry Module & V8FR-II RX
http://www.hobbyking.com/hobbyking/s...8FR_II_RX.html

And
FrSky DF 2.4Ghz Combo Pack for JR w/ Module & RX
http://www.hobbyking.com/hobbyking/s...Module_RX.html


Apart from the version 2.0 addition,I cant tell the difference,does the receiver with the more expensive option come with built in telemetry(So I don't have to use the hub with it)? :S
Kinda confusing :/
The DF has built in telemetry on the receiver. The DJT has a regular receiver. The modules are telemetry, but you can't use it unless you have a telemetry receiver. The one without telemetry can not do ANYTHING with telemetry, even with the sensor hub.



The DF module has a bundled telemetry receiver. You can plug in the voltage into this. For ANY other sensor, you need the hub, because the hub converts the signal types into the standard receiver type. To actually view the data, you need a screen.

I have made a perfect bundle for you with everything you need. This bundle should hold you over for at LEAST 5 years, as these radios are used by professional FPVers, and 8 CH is 4 CH more than you need as a beginner right now
You could save money by going cheap, but in the long run, you will need to upgrade sooner or later!

If you plan on staying in the hobby for some time, here ya go. This will NOT require soldering, or any modding.


Here are 2 transmitters. The first is always backordered, but is way better. The second is older, and unless you are comfortable with a soldering iron, it's not worth it.

http://www.hobbyking.com/hobbyking/s...dProduct=31544

http://www.hobbyking.com/hobbyking/s...Firmware_.html

You will need a battery for that transmitter. This is what works for me:

http://www.hobbyking.com/hobbyking/s...dProduct=20638

Here is the DJT module with the Telemetry receivers:

http://www.hobbyking.com/hobbyking/s...Module_RX.html


Here are extra receivers:

http://www.hobbyking.com/hobbyking/s...elemetery.html


You are going to want to know the voltage (Battery percent)

http://www.hobbyking.com/hobbyking/s...r_FLVS_01.html

Any other sensors will require the sensor hub


http://www.hobbyking.com/hobbyking/s...nsor_Hub_.html

This will tell you the GPS location, and your distance from you, and your speed. Also, if you crash, and you have signal, you can type the location in your phone and see it on a map.

http://www.hobbyking.com/hobbyking/s...PS_Module.html

If you solder connectors on this, it tells you how much power the motor and servos are using:

http://www.hobbyking.com/hobbyking/s...ge_Sensor.html

This little thing tells you how high you are, and whether you are climbing or decending

http://www.hobbyking.com/hobbyking/s...er_Sensor.html

In order to see anything, you need a screen. Unless you want to open up, solder, modify, and do stuff to your transmitter... you will want this separate screen to mount on the 9X. It has it's own cable to plug into the DJT module.

http://www.hobbyking.com/hobbyking/s...ay_Screen.html

If you want a little extra range:

http://www.hobbyking.com/hobbyking/s...e_Antenna.html.




So, you will need your sensor hub no matter what. Any sensors you want to have plug into the sensor hub, and the sensor hub plugs into your receiver. That is, only if you happen to have a telemetry receiver.


If you want to get started in FPV, and get about 1 to 1.5 mile range, here is what I have been using (Borrowed)

http://www.hobbyking.com/hobbyking/s...dProduct=28342

Better antenna:

http://www.hobbyking.com/hobbyking/s...dProduct=27750




These goggles and antenna include the goggle battery, camera, transmitter, and receiver. You plug in the transmitter/camera into your charge port on the battery, and turn on your goggles, and set them to same channel! There ya go! You have a full FPV system with rc and video link, combined with your bixler 2 for under $600 shipped, which is the best you are going to get!

These would be plug and play. If you get your bixler plane, you need a battery charger.

This is good, but slow, but cheap!

http://www.hobbyking.com/hobbyking/s...ger_2S_3S.html

This is what I use, and it is awesome!

For telemetry you get rssi and 2 voltages by default for additional info you need the hub or make it diy since the protocol is public.

Control works by connecting gnd +V and PPM. To get telemetry on the radio screen you need to do mods ir you can use the separate display module from frsky.

Unfortunately to have on screen telemetry it seems that you would have to mod the tx. and that involves some fine soldering to the processor pins to re-route 2 of the switches to other pins.. I think HK could have done this when they've designed/ordered the board.
There is a more or less solderless option, it's called TelemetrEZ, which is a little board produced by a forum user that takes care of those switches and telemetry and sends it to the processor without the very fine soldering. It has also some possibilities for later enhancements such a rotary encoder or even model storage. But this board was not yet tested with the 9XR obviously.

If you get the telemetry receiver, there are some sensors that you can connect directly to the receiver. Some others need the hub.. If you need only voltage, for example, there's no need for the hub. now if you need for example, GPS, RPM, fuel, you need it.

Oooops, I've just realized you were asking about the DHT-U and not the DHT.
It doesn't matter. the info can stay here, but I have some doubts that there would be enough space available to install the DHT inside the radio..

The DHT-U it is a plug and play RF module with telemetry screen, so you just need to plug it to the back of the radio to the pins in the module bay and you're good to go.

Hints that you could do something with it were already there in 2009 :
http://www.rclineforum.de/forum/boar...-70-au/Seite_8

If this radio had the screen on top it would have been near perfect for me. With connectors or even solder pads to easily add telemetry and sound extensions, it would have been all I want/need...Now only if they would restock the mode 1 I was foolish enough to order...

Have you tested it to make sure?
They actually shipped DSMX capable product before they officially released it. All AR8000 receivers for example.

Try following the instructions in the manual and see if it will toggle between DSM2only mode and DSM2/DSMX.
If it does then you can test it by first binding to something that you know is not DSMX, like an AR6100. Then bind to something that is DSMX.
If it will no longer control the 6100 (without rebinding) then your module does DSMX.
If you do try, do it in both transmitter modes. I seem to recall they have them backwards in the manual.

FWIW, there is another feature of the DX4e not mentioned in the manual - you can toggle expo on and off.

I'm guessing that no one is willing to flash their new 9x because of this...

So much for "The People's Radio".

What warranty? Haha



Yah the default firmware is slightly different I bet, so if you even try to restore the firmware, they know. I would back up the firmware, and if you need to return it, just restore it, and they will never know. Kind of like apple with jailbreaking.

PS on all those posts about FrSky modules, telemetry etc...
You can purchase all that stuff separately (like if you want a DJT with a telemetry receiver instead of having to get the one in the HK combo) at:
http://www.alofthobbies.com/
For virtually the same price and you don't have to wait two weeks. Fully warrantied and great customer service, and US based...

If you buy the HK combo with a telemetry receiver, or buy the receiver separately, at the end of the day, you get the same thing...


You can for the same price, but if he is going to be getting a Bixler 2 anyway, he doesn't have to pay for shipping.
