Hello,
Does anyone know if there are significant differences between the telemetry capabilities of the DX8 and DX18? As in, what can be displayed and what alarms can be set?

I know that the DX18 can log the telemetry data and that the DX8 currently does not. I wonder if there is any plan to add logging to the DX8. Or, they may never do so simply to keep the feature gap between the two larger.

I looked through the manuals of both but neither addresses newer sensors like the high-current sensor (nor does the Telemetry Compatibility Chart). What does the DX8 do if you plug that into the TM1000? One would hope that the firmware of both radios is kept up-to-date to handle new sensors as they are added.

According to the Telemetry Compatibility Chart, the DX8 can log telemetry data. Now I'm confused...

Thanks,
John

The telemetry functions for the 8 & 18 are basically identical.
They both log the data to the SD card(with current Airware).
The TM1100 provides basic telemetry but lacks the X-Bus port that the TM1000 has to add optional sensors.

Im not sure what leads you to think the DX8 does not log the data.Originally this was not a feature but has been added recently.Could be you got outdated info.

The only possible significant difference between the 8 and 18 is the dual antenna diversity in the 18 that does in my experience make the returning telemetry signal(and RF in general) more reliable.Beyond that the menus and options are functionally the same with one exception.
A menu for JetCat ECU data is being added from what I understand.IIRC it is only going to be available in the 18 at least for now.
It seems to make sense that they would add new features to the upper end radios first and then possibly some may trickle down based on user demand.We have seen how our radios are constantly evolving.I wouldnt expect that to change.

Well, let's see... None of the product pages (Spektrum, Horizon, etc.) for the radio nor the current instruction manual say that it does.
Originally this was not a feature but has been added recently.
Then maybe they should update the officially posted information for the radio. I also noticed that not all of the available sensors (such as GPS) are even listed on the Spektrum Telemetry page. However, if you search for "telemetry" they come up.

Thank you for confirming that it does now.
