FrSky DF 2.4Ghz Combo Pack for JR w/ Module & RX

FrSky DF 2.4Ghz Combo Pack for JR w/ Module & RX
FrSky DF 2.4Ghz Combo Pack for JR w/ Module & RX

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.
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).
FrSky DJTis compatible with JR transmitters following:
JR: 347, 388, 783, U8, PCM10, PCM10S, PCM10SX, PCM10IIS, 8103, J9303, PX, 9XII, 11XZERO

I flashed to a Turnigy 9x open9, this module will work with? I am looking to run failsafe and RSSI. it is good ?

Will this module fits into Jr 11x zero DSMJ ?

I got this module (FrSky), 2.4GHz 7GB antenna and TURNIGY9x transmitter more than one year ago to use on one of my projects. I didn't have a chance to use it. So finally a week ago I decided to go with it. Can someone tell me: 1) Can I use this module with TURNIGY 9X (not TURNIGY 9x PRO) just for pure flying for extended range with 2.4GHz 7GB antenna ( not telemetry) . 2) Can I Use PPM mode for that? What the difference between PPM and CPPM????????? 3) Do I really need changing it from PPM to CPPM to use it for long range?

1. Yes you can. 2. PPM and CPPM, pulse position modulation and continuous pulse position modulation, respectively. PPM is where radios encode stick position to translate it to the servos/motors, telling them how far and where to move. CPPM is outputting all incoming PPM stream (containing information for all channel positions, same as the Tx sends it) on the last channel of the Rx. It's used by some multi-rotor controllers so they can do all mixing onboard with a single connection between receiver and controller. It can give you more channels than what is on the receiver, but only as many as the tx pulse stream. So a one chan receiver can be used.

Will this module fits with Turnigy 9XR ? thank you

Yes Fits straight in.

I think I know the answer but I jut want confirmation before I purchase. I want to be able to use PPM - I have a FlySky FS-TH9XB which is the same as the Turnigy I believe. Can I buy this module and receiver and have PPM (single wire from receiver) to the Flight Controller. I will want to connect it to model using Cleanflight and need single cable connection. If it gives me better range etc. then that*s a bonus - I don't expect telemetry on my transmitter. Thank You

you need to reflash it to have CPPM out

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 for a review of the non-telemetry system. See for discussion of the Telemetry. Frsky have made the protocol PUBLIC so anyone can design sensors (are you listening Hitec??)

Frsky telemetry 8ch distance on ground test, on futaba 9c
The tx was cca 40m above rx points.
At 5.37 km distance the bind was working 100pcnt

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).

Bench tested using JR8103 and JR9303 transmitters. Antenna does not clear transmitter's handle and must be removed to install module. Fit is excellent, snaps in tight. My Spectrum DSM2 module does not fit well and has lost connections while flying. Binding was easy, I read the instructions 3 times before realizing it was already done, it is much faster than Spectrum. tested with V8FR (non-telemetry) and D8R (telemetry) receivers, great results

This is a review on FRSky DJT V2 module combo. I ordered this combo from Hobbyking. Arrived in about 14 days from HK to Europe. The module works well in a Graupner MX-22 and binding was very easy. The signal is smooth as you know it from Futabas Fasst or Spektrum DSM2. Reconnecting after signal is lost (turn TX or RX off) is very fast. Didn't tested it on the field until now, but first impression is very good. I would like to see a Telemetry HV receiver for 3-16V. So I can use high voltage servos in a big helicopter and don't have to worry about brownouts. A certificate for European countries is available now (2010-12-24) at FRSky website. So no need to buy it in Europe, where you pay twice the amount.
