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 (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).
Receiver Specification: Operating voltage: 3.5 - 10.0V Power consumption: 100mA Resolution: 3072 Latency: 22ms Analog voltage: 0~3.3V Number of channels: 8 Range: 1.5km-2.5km Dimensions: 55 x 25 x 14 mm Weight: 12.4g Version: 2.0
Yes, but not immediately. It requires to flash the firmware for the one of the D8R-XP. Instead you could buy directly a D8R-XP that has the correct firmware for CPPM output, if channels 3-4 are bridged.
...I also cut the gray antenna wire closer to the stock antenna and then mounted an RPSMA 90 degree connector to the back plate of the stock TX module...the gray wire is a coax and the soldering of the center stinger and then shielding the connection with the outer shield is a bit difficult, but can be done. I can then use the FrSky antenna. Now I can swap between TX modules with ease.
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 www.link 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 http://rcmodelreviews.com/frskyreview.shtml for a review of the non-telemetry system. See www.link 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 www.link
