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).

does this work with the 9xr
Matjaz  2 points - 1/19/2015
Hello, I have the D8R-II Plus / DJT combo. RSSI signal is fluctuating between 99 and 75, even when I hold the transmitter close to the receiver (1-2m). These drops to around 75dB seem to happen at some strange TX positions (but not pointing the antenna directly at receiver). I also had a crash recently with my quad no more than 500m away (300m high and about 300m horizontally) because of signal loss (went from a beep to fail in seconds..). I am wondering if someone has experience with this? RSSI just SUDDENLY switches from 99 to 75 and then back to 99 with small movement or touch of antenna. I disassembled everything and contacts seem to be very firm. Looks like perhaps it's switching between antennas on RX and one of them soldered badly? Or one of them faulty? What options do I have to test? BR

I have done both. I have removed antenna from TX and switched it on, but only long after I've already discovered the problem - to test if antenna is somehow responsible. I've also modified TX module for 9xR telemetry. It's just one connection and looks clean. RSSI drop only occurs in some TX antenna orientations - a couple of centimeters can be a factor. I had another crash today (a flyaway) but I lost signal well before 1km line of sight, perfect conditions. I have tested TX-RX with RX only connected to 5V power. The results are the same. I ordered another RX unit today, but it may well be TX. I will report more on this. Thanks.

I gor this TX few months ago! Had a couple of good flights, but someday, as everybody knows, quadcopters fall ... thats ok ... in my last crash, the wires of my TX got broken ... its ok ... so I opened the TX for the first time, to sold the plug where it got broken look what I found ... THERES A NASTY GLUE STICKING OUT FROM THE TX IM UPSET RIGHT NOW *sorry bout the poor english target=_blank>NASTY D8RII-PLU

It might be the glue on the pots, they usually use glue to hold the wires to the pots.

Does the telemetry works as soon you plug the FrSky telemetry module to the Turnigy9x running Open TX Firmware or do you have to modify something on the transmitter? The reason i ask is there are soooo many videos and info out there about the cheaper DIY FrSky module and how you need to hack the Tx for the telemetry to work... I have Turnigy 9x running OpenTX Smart Parts LCD Screen
 MrCuss 6 points
OK. A little digging and i now know that soldering IS required. Fortunately i installed a 'Smarty Parts Board' to my 9X and 'Flashed' the Firmware to openTX a while back so again i turn to Smarty Parts who have created a board that does all the hard work for me... $22 shipping for a small board that clips to the Smarty Parts Programmer board and allows the integration of telemetry from the FrSky Module without ANY soldering. I just need to confirm open 9X is the right Firmware as it looks like er9X is already compatible with my hardware and the modifications i have made.

I'd appreciate if anyone could share a buddy code for this combo pack. (no code on rcsearch)

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.
