When I do full right with stick - then servo moves to its limits.
It moves only on full input, and nothing between center and full input.
Looks like it lacks something to work properly.
Any ideas?
I am afraid you need to do a bit more than load RX firmware on the TX.

firstly which TX unit you are hacking ?

Can anyone tell me the differences between the DTF UHF DeluxeTX and the HawkEYE openLRS UHF?

You need to be a bit more specific as hawkeye makes dtfuhf versions too.

Hello,
I adapted a Futaba Hawkeye LRS 1W to a Hitec Aurora 9 but now, I want to know the firmware version of the TX and update it.. but I don't know how!? Please, do you have a manual to see the pinout? I have a 5V FTDI, and a USBasp ....

In this picture, you can see the pinout: http://www.fpvmodel.com/img/433-hawk...hz-HawkEYE.jpg
What is the function of the right 4 pins: GND, SDA, SCL, VCC ? Can I flash the module through this pins?

Here, my FTDI: http://gallery3.mikrokopter.de/var/a...g?m=1409747879

Regards.

Is it possible to build 2 of these boards with RFM23BP 915Mhz Modules, upload to it the openLRSngDL firmware (which is the openLRSng only for telemetry data) and use them as a 1W high power telemetry modems? something like the RFD900?

I would also like to know if diversity could be implement in it (like the RFD900), I've seen the BROVERSITY RX Receiver, an openLRS receiver with diversity built in, according to the schematics, this is achieved with a SKY13267 CI connected to some GPIO pins that selects which antenna to use. Apparently, the RFM23BP module supports diversity "out of the box", only a few registers must be altered.

Do you guys think that something like this could be built and work??

I think I left diversity support in the DL version not sire about that but if it is in config ot should work.

I compile firmwares for 868 and 915 too so modules with swapped rfms should work. Worth noting the lfcn filter must be changrd to higher freq one or a 0r resistor.
