Support/FAQ for RC-Soar templates
This page is for support of the RC-Soar templates.
Supported operating systems
The RC-Soar templates are compatible with both OpenTX and EdgeTX.
OpenTX is a mature, stable operating system. However development has stalled, and it does not support newer radios.
- Recommended version is 2.3.15.
- Avoid 2.3.12, and 2.3.13 if using ISRM/Horus (servo stutter issues)
- If running 2.2.x or 2.1.x, check template for compatibility.
EdgeTX is a fork of OpenTX, and is the current focus of development. The programming is identical. The main difference is that EdgeTX offers a touch interface for radios with touch screens, and better support for ELRS.
- Recommended are versions 2.7.1 and later. Avoid 2.6 (critical GV bug).
- Currently EdgeTX does not support mixer scripts, so the advanced snapflap script cannot be used .
Migrating from OpenTX to EdgeTX
If you're considering migrating to EdgeTX, note the following:
- Model data from OpenTX 2.3 can be imported and converted via EdgeTX Companion.
- Model data from OpenTX prior to 2.3 should be converted to 2.3 in OTX Companion 2.3, then imported into EdgeTX Companion.
- Model data from EdgeTX cannot be converted into OpenTX format.
Always backup your data before migrating.
Using the RC-Soar templates with ELRS
ELRS is an open source RF protocol which is rapidly gaining popularity due to its combination of low price, high range and robustness. Here are some notes on using the templates with ELRS.
Channel 5 requirements
For historical reasons, ELRS maintains an 'arming' state which is controlled by CH5. The easiest way to deal with this is to:
- Move CH5 to the next unused channel (you may want to use my Channel Changer script).
- Set the source of CH5 to 'MAX' to indicate 'permanently armed'.
For further info, please see my blog post Introduction to ELRS: Managing Channel 5.
These settings are based on the devs' recommendations for line-of-sight applications, and work well with the CH5 mods above.
- Packet rate: 100 Hz
- Max RF power: 100 mW
- Dynamic RF: enabled
- Switch mode: 8 CH full res
- Telemetry Ratio (TLM): affects telemetry data rate - use the default value. Exception: for DLG setups with launch height callout, a lower TLM ratio may be required to capture launch height with sufficient precision.
Issues with the RC-Soar templates
There are currently no open issues
Converting a template for EdgeTX or another transmitter
The RC-Soar templates target the FrSky X9D on OpenTX. To convert a template for another transmitter or to EdgeTX:
- Launch Companion (use the version for the operating system on your transmitter)
- Select or create a profile for your transmitter
- Open the template file. Companion will perform the conversion.
Starting with OpenTX 2.2.2, Companion displays if conversion issues are encountered. Usually no action is needed. However if there's a genuine issue, it's best to correct it in Companion.
Save the setup as a .otx (OpenTX) or .etx (EdgeTX) file. This is now your working template, ready for transfer to your transmitter.
Copying a template to your transmitter
Here's the recommended way to move a template from Companion to your transmitter. It preserves your existing models and radio settings, including stick calibrations.
Note: If using EdgeTX, or a transmitter other than the X9D, convert the template file first (see previous section for instructions).
Here's the procedure for adding the template to your transmitter:
- Start Companion and select a profile for your transmitter.
- Open the template file. The data is displayed in a new window.
- Connect your transmitter by USB and choose "read models and settings from radio". This will open a second window.
- Drag one or more models from the template window to the tx window.
- Close the template window. There should now be a single window open for the target transmitter.
- Choose 'write models and settings' to update the transmitter.
- Copy all model-specific sound files to the target's SD card.
- Disconnect the target transmitter.
How to report issues
If you find an issue, please email me with the following detailed info:
- Template name & version, transmitter type, and OpenTx version
- Enough info to reproduce the problem
If there's insufficient info to reproduce the problem, I'll just pass it back, so please take the time to document the steps carefully.
- Motor control (CH7) is not working on G-RX8 receiver
- Make sure that CH7 is configured for PWM output (and not S.BUS out). See receiver instructions.
- A switch is missing from the dropdown list
- Sometimes, a switch which exists on the transmitter may be missing in the drop-down menus of the radio and/or Companion. To fix this, go to the System>Hardware menu. The chances are that the switch has not been defined. Once corrected, the switch should appear in the dropdown menus.
- Where's the GVARs menu?!
- There's no dedicated GVARS menu on tx's with small mono screens like Q X7, X-Lite, and X-Lite Pro. For these transmitters, the GVARS are set in the Flight Modes menu.
For all other transmitters, the most likely cause is incorrect settings when downloading the OpenTX firmware. Re-flash OpenTx ensuring that the NOGVARS option is unchecked in Companion Settings -> Build options.
- How do I re-order the servo channels?
- Servo channels can be re-ordered using Channel Changer script
- I think I've pressed the wrong key - help!
- If you suspect you made a data entry error, then there's no need to start again. In Companion, load a .eepe or .otx file containing a known working version of the template, and use Companion's 'Compare models' tool to identify any differences.
