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).

Have a JR3810. Does this module is compatible?
 skyfox60 966 points
Be aware, there are two DF combos, product ID is DFT for Futaba and DJT for JR transmitter. Be sure to choose the right one. For JR you need the DJT module.The "J" stands for JR compatible, which means the outer size of the plastic housing to fit in the transmitters slot.Hope that helps

Or a simpler answer would be: Yes, it is compatible.

When will this be available in EU WAREHOUSE?!
 AlbEagle007 544 points
They don't sell this in EU Warehouse i think :( . You will have to order it from the International Warehouse. That's what I have done.
 skyfox60 966 points
Not sold in europe because of contracts between FrSky and local distributors. So, it is available in europe, but not from HK.( unfortunately btw. )IF you have some time, just order in int-wh. Otherwise use google to find elsewhere. My FrSky-stuff comes from HK int wh. All good so far. Hope that helps.

Hi everyone I was using this module for my 9x.... and I just know what the beeping sound when I fly my plane like 700 - 1000 meters away is that mean that im loosing signal ??????????? Its not the battery......
 Adrian 7 points
Beeping sound was coming from my 9x
 Lukasz 50 points
Yes, it's one of the telemetry functions. The module makes this beeping, changing into a constant signal when the signal is getting weaker. If the module beeps, it's still not too late to turn around :) Still, with the distance of 1km You shouldn't have range problems, I flew it with 4m sailplane probably 2km away with no beeps. Check RX antenna placement in the model.

Will you have this item or
in Europe wharehause for the turnigy 9XR transmitter? Because there are the transmitter but aren't the transmitter module in 2.4Ghz
 skyfox60 966 points
No, it will not be possible, because of different sales contracts between FrSky and some european resellers. That is, why you can only order it in Hong Kong.

Stupid question, I understand that you get signal feed and Rx voltage feed without using any additional sensor, I know that the Rx voltage feed is not reliable because of the ESC/BEC, so what if I'm using HV servos and a 2s Lipo in direct connection to the Rx ? Would I get a voltage telemetry similar to the one of the Lipo Pack ?
 BigD's 34 points
I think the answer is yes...
 AlbEagle007 544 points
It is very easy to build a voltage sensor if you can't buy one. You only need two resistors and two pieces of cable, that's all. I have built a voltage sensor for 3S using 1x 1.5 K and 1x 4.5 K resistor, connecting to A2 - G
 Axel 14 points
I actually have one, what I don't have is space in my sailboat, thanks anyway.

hi ,,you can boost that ,,step up 3v to 5 volt booster .available Hear. I seen somewhere.

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 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 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??)

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)

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
