FrSky DHT 8ch DIY Telemetry Compatible Transmitter Module
FrSky DHT 8ch DIY Telemetry Compatible Transmitter Module

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!

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 (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.

Please bring back the V8HT................................................
.. This
unit is nice if you need telemetry. For most of us doing a DIY MOD on an older 72 Mhz radio telemetry is not needed and this new PCB is bigger and has an extra switch that makes mounting difficult. I think you could still sell lots of the older transmitter units as the price was better too.

Hi, does anyone know what the four pins at the bottom of the module are for? They are covered by some plastic part on the pictures above, and I don't know if I should connect them or anything. Thanks

They are the telemetry connector pins. I keep them disconnected, covered with the plastic cover, because I don't use telemetry. Regards!

There is an LCD that have to be connected to the four pins, it shows the Telemetrie datas

Thanks for both yours answers, i'll just keep them covered then :)

My package has not been delivered since 08/01/2015. why does it take so long?

Hello Rico, try contacting 24Hr Support Centre. They always solved my issues. Only ones it took a long time because there was a parcel returned to sender, and it demands some time to be checked and solved. Good luck!

I would like to covert my futaba t6exhp to a 2.4ghz. can I use this module and what must I do with this conversion?
 EstebanT 698 points
Yes, of course you can. I will try to tell you briefly how to do this. Is very easy and safe. First of all, you must find where to solder the three module wires (power positive and negative wires and ppm signal wire). A good starting point for this is thru the trainer cable port. With a multimeter you can identify positive and negative power pins when voltage reading equals the battery voltage. PPM signal pin will measure about the half of the battery voltage when measured against negative pin. An oscilloscope can be used to confirm PPM pin. In the "FILES" tab above I uploaded some pictures showing this when I fitted this Rx to my old Futaba (see "PPM Signal in FUTABA FP-T6NFK"). Once the pinout is obtained, you will open your Tx casing, find a good place inside to locate the module, replace the antenna, solder the module wires to the appropriate pins, locate binding button and led, locate mode switch, and close the case. Thats it. Wish you good luck! Happy 2015!

Hi! I want to upgrade my two oldest radios a Futaba FP-T7UAF and a KRAFT series 77 with this module, can you help me finding out if it is going to be possible? and if there is a "how to" video or tutorial on line to make sure I can do it before I order? Any help would be really appreciated! Thanks!

Look at the replay over here, Dont now if the KRAFT series 77 has a ppm Output?

I instaled this module in my futaba fx-18 easy as a pie.Cut power wires to old 35mhz part use those wires for powering DHT module,solder yellow wire to ppm signal in the back of trainer plug.I unpluged toggle switch(now it is impossible to make a mistake or bump this switch when in air with model) default setting is 2-way mode. when needed for fw upgrade i can plug it back and remove after.

Great device! I Installed it in my Graupner FM314 and it works fabulous! Even without TX antenna the signal is strong enough to span 10 m and more. Thats enough for my truck. The only bad thing is, that I cannot use two D8R receivers at the same time at one TX. Previously I used two RX. One in truck and one in trailer. Does anybody know, if this works with the V8 receivers?

I just received the DHT Module and a 8 channel receiver. Installed in a Futaba T6XAS today and it is working fine no problems installing. I mounted the switches and bind button on the back side just above the trainer plug outlet. The main module was mounted against the CPU on the Futaba using double sided foam tape. The antenna was mounted in place of the 72MHz one. Binding was great no problems binding to the transmitter. I checked all six channels and all are working with no jittering noticed. I will try a range check tomorrow and maybe fly in a plane on Sunday.

Installed at FUTABA T6XAS.The telemetry is a good auxiliar tool to fly with thermal planes when you go far away from you. The beeps from RSSI alarm advise you of the condition of RF Link.
