In case you do not know something or you are not sure, here is the right place for your question.

Hello everyone on the forum,
I installed the RX with connections to the SYS port (TX/RX) and power to the Rud port (+/-) following the "CrossFire CRSF" manual with Spirit firmware 3.7.4.

The radio sees the receiver, telemetry, and can use "Radio Integration." To do this, I had to download the latest release of elrV3.lua and replace the existing one.

Introduction: With a receiver such as the SPM4651T that connects to the Rud port (pin +/-) and AIL pin, you can also connect the "USB interface" to the SYS port to adjust the stick travel using the diagnostics screen as per the manual.

Question: Returning to the "CrossFire CRSF" manual where the connections (TX/RX pins) are connected to the SYS port, where do I connect the "USB interface" cable? Or how can I calibrate the stick travel using the diagnostics? Is there an alternative method?

9 Helicopters would thank you for a reply.

Regards

you have edge tx?
it s possible integration with edge tx ?

My radio (Radiomaster Boxer) is edgeTX and all the setup parameters appear but not the diagnostics.

and what did you download from the site?
in the site there is integration:
spektrum
jeti model
open tx
graupner hot
ethos
I'm attaching a photo for you
i have tx16s with edge tx and I want integration too spirit software in my radio but i use multimodule and no elrs

Hi, since I also have an EdgeTX on my Boxer, I haven't tried the "lua" software for OpenTX, but I remember from a previous post that it wouldn't work with EdgeTX.

However, I tried the integration on the Spektrum radio, and it works for parameter setup.

I also have the WiFi and Bluetooth interface to use the smartphone app, but that's only for setting up flight parameters.

So far, I've only been able to run diagnostics via the USB interface, keeping the Radio - RX - FC - and PC connected.

The diagnostics are needed to calibrate the sticks with the flycontrol (Spirit2). The stick calibration is done only once when you change receiver or radio.

I think anyone who knows is on vacation!!!

on my radio jeti integration is ok.
if I could I wanted to add integration on my radio tx16s edge tx.
in integration you don't have all the options identical to the USB cable.
if I remember correctly diagnostic in integration it is not present.
but I never use integration why once the helicopter is turned on and customize two or three parameters I don't use integration anymore.
The helicopter when it flies well I have no reason to move it.
I didn't know with elrs you had to calibrate stick, i know with elrs you only had to see the channels full duplex.
Type channel 5 it only has the off and on position after channel is all 1024 usec or 2048usec 8(for this reason I don't use elrs i heve multimodule and elrs module but elrs module it's too complicated channel full range, channel with only position off and on ecc)

ELRS does not offer this diagnostic.
Diagnostic works with Lua script when using SPORT, FPORT or FBUS with both OpenTX and EdgeTX.

Each protocol and receiver has own limitations, ELRS have probably the biggest limitations from any available protocol. But it is well marketed so popular these days.

If you follow the instructions in the Spirit2 manual or any other FC (Brain2 - Mikado - etc.), you'll find that if you change the transmitter and/or receiver during setup, you'll need to recalibrate the sticks.
This is because even a small frequency change (error) in the chain is enough for the FC to read that the aileron stick is set to +3 by default instead of 0, and this is interpreted as a command. The same goes for all transmitters and receivers (in fact, the error in one or both is corrected).
For the other options listed below, there aren't many problems as they are on/off or, in any case, activations that are noticeable in flight:
- A channel to adjust the tail gain (which becomes constant for each bank: Normal, IdleUp1, and IdleUp2). Typically, these are two values: Normal and IdleUp.
- A channel to adjust some parameter such as cyclic gain (for example).
- A channel to switch between bank settings (with specific setups based on speed and Hely activity)
- A channel to activate aerobatic rescue (a sort of insurance if you lose control (blinding or loss of nose-tail orientation).

I have the NOMAD (GEMINI) ELRS module for two reasons:
1) To have a higher transmission power receiver, as I monitor two parameters such as battery charge and blade speed.
2) Control speed (Spektrum 22msec vs. ELRS 5msec)
3) Experimentation

I currently use Radiomaster Boxer 4IN1 with SPM4651T receivers with Spirit2 on all my helicopters, and although I initially had problems with the OMP M4, M4Max, M5, M6, M7, etc., I've now achieved an excellent setup for myself. I have no intention of giving up the Spirit2 as I consider it an excellent product. In fact, even though it's not integrated with my radio, I don't have any problems; I can just leave it as it is.

I don't particularly like radio adjustments because they're a distraction (besides being a convenience).

But express elrs It has full range channels and other channel with limited positions.
Is exact?

There are many parameters in ELRS:
- Number of channels (16 from what I've seen, although I set it to 8 total)
- Number of updates, which defines the command latency
- Connection frequency: 900 MHz is effective even with obstacles, but the resolution is low. 2.4 GHz has the highest command resolution.
- Telemetry update: which determines the latency, i.e., off, 8, 16, 32, 64, 128, which is 1 telemetry packet for every 8 command packets.
- Transmitter power from 25mW to 1W per channel (Gemini has two that can be set in combination: two at 900MHz or two at 2.4GHz for a total of two watts, or a 1-watt hybrid of 900MHz and 2.4GHz)
- Receiver power in mW (higher than Spektrum full-range antennas), number of antennas (max 4), frequency (900MHz and/or 2.4GHz), and RX response (latency based on the parameters above)
- etc.

This is what I've seen so far, even watching videos on YouTube. I can't tell you more.
