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
No. 50mA is the input power (50milliamp), which is the power consumed by the module. The antenna is 2db (approximately), and is more than adequate for FPV to about a mile. You would lose sight of your model long before losing radio contact, so not additional antenna is needed.
Thanks EffinA. If I use this module which has Range: 1.5km-2.5km with FrSky 2.4Ghz 7DB antenna $5.51, the range will be 3 times longer, about 4.5km-7.5km. Right? Now, if I use that with my RC boat (surface), do I consider range drop , let say, at least 2 times. So my boat RC boat will have range about 2-3km? Also If I detach antenna and put it on 8 meters high pole supplying it with longer power cable, should it increase the range again? What you think? I need to control my RC boat within 2km range. Any ideas?
That's a bit of overkill, but remember that the higher the db of an antenna, the more directional it will become. For an RC boat, it won't be too much trouble, but you will have to pay attention to the orientation of the antennas
How am I supposed to put the two thin antenna cables coming from the RX?
Should I just let them move freely? Or should I put one of them horizontally and the other one vertically for best performance? Thanks
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??)

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
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.
