The DHT Transmitter Module is a great option for radios that can not use one of the plug in modules. The module is compatible with both the V8-series (non-telemetry) and the D-Series (telemetry) receivers.
Advanced Continuous Channel Shifting Technology (ACCSTis 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).
The DHT is compatible with any existing transmitter where you can tap into the PPM signal.

I purchased this to put in my FlySky TH-9x it was the model with the integrated antenna so I couldn't use one of the plug in modules. I followed several of the many install tutorials on YouTube including RCModelreview. It wasn't difficult, but It did require some soldering, drilling and hot gluing to get it all to work. I've had it a few months and it works great with my FrSky receivers. I now have many more choices available in terms of receivers. I recommend looking at the install tutorials first and making sure you are up to the mods, but they aren't too tough and it's a really worthwhile upgrade.
I've installed this module in two Airtronics and one Futaba radio with no problems and all bound to a receiver the first try. The specific radios were all 72 mhz and were an Airtronics 6 channel Radiant, an Airtronics RD6000 and an old Futaba 7channel gold box FP-7FGK. The Futaba was my first radio years ago and I converted it just as a nostalgia piece but it will be used (probably with some of my old nostalgia planes). The Futaba I did by following some instructions I found on the web and with both Airtronics I used a pair of headphones and a voltmeter to figure out the signal, V+ and ground lines on the back side of their trainer jacks. On all three I also added a red LED that lights up when power is turned on-just as a "visible from a distance" indicator to let me know my radio is turned on. I'm very happy with the way these modules installed in all three of these radios and I definitely recommend them. I have more 72 mhz radios and would happily convert them too but just how many 2.4 ghz radios does one guy really need??
installed in a jr xp8103 and worked in a snap...tested all ports...all ok
shipping was quick and well packed
I've been flying with this module and it's predecessor (non-telemetry) for well over a year, now, with no problems. The modification was easy to do (how to can be found on RCGroups) and works fine. The module was able to fit into the case, and by replacing the antenna cable with a longer one, I was able to mount the antenna where the 72 MHz antenna used to sit. All in all a great way to extend the life of a great TX
I received my order in no time. Great service! The module works great in my TGY 9X flashed with er9x. Much better than the original transmitter modul and with this transmitter I got the telemetry which enables me to check battery condition and more from my heli.
I definitely get my FrSky stuff from Alofthobbies.com in the future since I receive it much quicker then from Chinese sources and they have very competitive pricing. Thanks for making the FrSky modules available directly from the USA!
I added this to a Turnigy 9x, along with a smartieparts board and flashed it with er9x. This makes one nice radio. The FR Sky 2.4 stuff is great. Have telemetry on the radios built in display. If you are adding this board and using the newer receivers that is no need to mount the toggle switch to the radio if you are using D series or the newer V series that work with both protocols. If you would ever need to flash the module you can plug the switch in for the upgrade, as you would have to open the radio anyway. Great product and great service from Aloft.
