Has anybody developed a protocol for the Futaba FHSS mode. the S-FHSS that comes with the 8G will not work with an FHSS only receiver.

As far as i know no... I too have a few RTF planes using the FHSS protocol, and i would very much be interested, but if i remember correctly in another discusion, the FHSS protocol is considered to be too old, and with low channel count (only up to four i think), and it is not worth researching. Still, i would love to fly those planes with the advanced features the Deviation provides... Maybe one day...

It's not that it's not worth researching, just that no developer has a FHSS transmitter in his hands, and nobody has posted SPI dumps of a FHSS transmitter either.

Ich habe hier ebenfalls das Problem.

Ich habe hier einen kleinen Hubi mit FHSS Protokoll stehen.
Den würde ich auch gerne mit meinem Jumper T8SG binden. Leider klappt das nicht mit dem SFHSS Protokoll welches im T8 Sender ist.
Es wäre schön, wenn sich einer dieses Problems annehmen würde.
Ich wäre euch sehr dankbar.


I also have the problem here.

I have a small Hubi with FHSS protocol here.
I would also like to tie with my Jumper T8SG. Unfortunately, this does not work with the SFHSS protocol which is in the T8 transmitter.
It would be nice if someone would take care of this problem.
I would be very thankful.

You need either to dump yourself the SPI bus and help testing, or send your TX & RX to one of us so we can work on it.

Ich danke Ihnen für die Antwort, auch wenn mir das im Moment nicht weiter hilft.
Der Hubschrauber ist der Carson Zermatt ein Koax Hubi der nicht mehr im Programm ist.
Zum Verschicken ist der mir etwas zu gross. Der Empfänger der da drin ist, ist ein 4 in 1 Empfänger.


Thank you for the answer, even if that does not help me at the moment.
The helicopter is the Carson Zermatt a Koax Hubi is no longer in the program.
To send me something is too big. The receiver in there is a 4 in 1 receiver.

If you don't want to send a TX+RX (Pascal & I are located in France, not too far away from your place ;)) you can help by dumping the SPI bus in the transmitter:

Ich bin jetzt leider nicht der Elektronik Fachmann.
Und wie lade ich den SPI Bus in den Sender??
Wo bekomme ich den SPI Bus her?

Unfortunately, I'm not the electronics specialist right now.
And how do I load the SPI bus into the transmitter ??
Where can I get the SPI bus?

That is explained in the video in the topic I linked, You only need a 5€ logic analyzer then solder a few wires into the transmitter.

Can you take a picture of the inside of your transmitter, so I can tell you if and how it can be done ?

Ich soll also meinen Sender Jumper T8SG aufschrauben und dann von der Rückseite der Platine ein Foto machen und hier hochladen.
Habe ich das richtig verstanden??

So I'm going to screw on my transmitter Jumper T8SG and then take a picture from the back of the board and upload it here.
Have I understood that correctly??

No, the inside of the FHSS transmitter.

Der Sender T8SG ist ein Open Scource Sender der über 40 versch. Funkprotokolle kann. Und eines von diesen Funkprotokollen die ich da einstellen kann ist S-FHSS.

Welchen Logik Analyser soll man sich denn kaufen. Was soll der alles können?
Welchen würden Sie mir empfehlen?

The transmitter T8SG is an open source sender of more than 40 different radio protocols. And one of those radio protocols that I can adjust is S-FHSS.

Which logic analyzer should one buy? What should he do?
Which one would you recommend to me?

I know what a T8SG is and I do not need any picture of it ;)
I need a picture of the inside of your original FHSS controller.

For an analyzer, just go to ebay and search for "8ch logic analyzer", it should cost about 5€ ...

Where in Germany are you located? You need to open up the transmitter which came with the helicopter and show us pictures from the inside, NOT the Jumper.

Moeder, if you speak German please tell him what I'm trying to say, I'm sorry but I don't understand a single word of German and I think he has the same issue with English ;)

I'm also worried that this protocol discussion has started with Futaba FHSS and he is talking about something else since FHSS is usually written on a lot of different systems...

Sorry, mein Fehler
Wir reden hier von Futaba FHSS.
Ich habe hier einen Carson FHSS und das ist scheinbar wohl nicht dasselbe wie Futaba.
Nach so einem Logik Analyzer werde ich schauen.


Sorry, my mistake
We are talking about Futaba FHSS here.
I have a Carson FHSS here and that does not seem to be the same as Futaba.
I'll look for such a logic analyzer.

Even if it's Carson branded perhaps it's using the Futuba FHSS protocol, we've already seen Carson stuffs using the AFHDS-2 protocol.

Danke für die Info.

Ich werde das morgen mal mit dem AFHDS-2 Protokol und meinem Cason Modell testen.
Werde morgen berichten.


Thanks for the information.

I will test it tomorrow with the AFHDS-2 protocol and my Cason model.
Will report tomorrow.
