Manual Has Conflicting Information About SRXL2 Wiring

[ShapeShifter]

Which is the correct way to connect Spektrum SRXL2 wires to Spirit GT?

OR

https://manual.spirit-system.com/index. ... SRXLGT.png OR https://manual.spirit-system.com/index. ... wiring.jpg

Please tell me the correct method. I'm afraid I will damage the unit.

One is SRXL (older protocol, one way communication), the other is SRXL2 (bidirectional with telemetry), I'm assuming that's the reason for the difference. Main wiring page is still incomplete as it's missing the latter as well as CRSF wiring, already reported this 6 months ago. Unfortunately the manual is very disorganized and some parts are not wel maintained. Telemetry page has the same issue.

Hello,

actually there is nothing conflicting.
You are looking at photo from different SRXL protocols. SRXL and SRXL2 are very different.

If looking at SRXL2, wire according SRXL2 page:

Can you let me know what is disorganized and missing?
CRSF is described for all our units, see this page:

The page is there when you manually search for it, but the main wiring page that most users will use to look for this info is missing both CRSF and SRXL2. This probably also caused the confusion here.

The information that is there tends to jump around a bit and formatting is inconsistent. On the main page "Wiring" it would be much cleaner and easier to navigate to just link to dedicated pages instead of duplicating some of the information there, easier to maintain too. Currently there are some seperate pages like Spektrum SRXL2 and CRSF you need manually search for, while several others are only described on the Wiring page.

Especially the tuning guide could use an overhaul for v4 new parameters and typical values with more concise descriptions. There is no clear separation between tuning performance/accuracy and flight feeling, and the descriptions can be long-winded in some places while other parameters are barely explained. There are also conflicting things like the tuning guide telling you to always set tail gain first and at this point only, and after this step raise piro consistency, but some of the presets already start with a high value here with no way to know the default unless you reset the entire unit.

The ESC telemetry page doesn't mention XDFly/ZTW, most users won't know they have to go to the OMP page. On the Spirit Wave version of the page it does mention these.

Some info isn't updated like Futaba telemetry only shows up to 18SZ and some specific receiver models are needed, but there are a lot more newer ones that work. Any Fasstest receiver should be fine, no need to mention specific models that are out of production.

Hobbywing v5 telemetry only shows Platinum 150A is supported. This has led to questions on the support forum before if 180A/260A are usable.

This goes for the pc software as well; parameters like flight style, rotation rate, feed forward are mostly user preference and largely influence how the helicopter feels but they are spread out between General, Sensor and Advanced tabs. The way banks are presented could also be much improved if there was no need for switching back and forth. Expert tab has some settings that are user preference and others that are basic setup and could be absolutely critical for correct functioning. If setting up banks from a user perspective I would just prefer something like a list of parameters that can change with three columns for bank 1-2-3 instead of constantly switching banks and clicking around 5 different tabs. The bank comparison function already almost does something like it, but you can't edit the values.

These are just the ones I could think of for now. For me personally I don't really care, I already know most of this stuff, but when helping new users set up it's something you always run into.

Thank you very much for detailed description. It was very helpful and we already fixed many of these issues.
