Support/FAQ for Pro Templates

Last updated 3 May 2022
This page is for support of the Pro templates. Here you can determine which OpenTx versions are supported, any known issues, and how to migrate your setups.
Supported operating systems
OpenTX 2.3
- All Pro templates are compatible with OpenTx 2.3.5 and later.
- Avoid 2.3.12, 2.3.13 if using ISRM/Horus (servo stutter issues)
- Avoid RCs and nightly builds.
OpenTX 2.2
- All Pro templates are compatible with OpenTx 2.2.1 and later.
- Avoid RCs and nightly builds.
OpenTX 2.1
- Old branch
- Current Pro templates are not compatible. Older versions of the templates may be compatible, see template version history.
EdgeTX
EdgeTX is a fork of OpenTX with leading edge features including touch support for the TX16S. It is less stable than OpenTX. If using EdgeTX with the Pro templates, please observe the following:
- Recommended version is 2.7. (Do not use v2.6 as it has a critical GV bug affecting the Pro templates).
- The template setup guides are written for OpenTX. EdgeTX has the same programming menus, but navigation between menus may be a little different.
- To reduce the risk of accidental changes it is strongly recommended to disable touch when using the Pro templates! Touch can be disabled in 2.7 via a special function with action = 'No touch' and switch = 'ON'.
- Currently ETX does not support mixer scripts by default, so the advanced snapflap script will not work.
-
Test all functions extra carefully before flying. If in doubt, do not fly.

Pro templates FAQ
- 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, 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.
Using the Pro templates with different transmitters
The Pro templates are built for the X9D. To convert a template for another transmitter: launch Companion, select a profile for the target transmitter, and open the template. Companion will perform a conversion.
Starting with OpenTX 2.2.2, Companion displays warnings if it encounters any conversion issues. Usually no action is needed. However if there's a genuine issue, then make sure to correct it in Companion before uploading to the transmitter.
In the example below, four mixes need to be verified; no correction is required since the 'old' and 'new' columns are identical.

Transferring models to another transmitter
At some point you may wish to transfer all your models to a second transmitter.
- The source and target transmitters can be different types, however the target must have the same or higher major version of OpenTx, for example source=2.2.x target=2.3.x.
- The version of Companion should match the version of OpenTx on the target transmitter.
The method described below will preserve the radio settings (including stick calibration) of the target transmitter.
- Start Companion, select a profile for the target transmitter (create a new profile if necessary, remembering to select the correct radio type).
- Connect the source transmitter by USB and choose "read models and settings from radio".
- If Companion encouters any conversion errors, these must be fixed in situ before proceeding.
- Disconnect the source transmitter.
- Connect the target transmitter by USB and choose "read models and settings from radio". This will open a second window.
- Drag your models from the source window to the target window.
- Close the source window. There should now be a single window open for the target transmitter.
- Choose 'write models and settings' to update the target transmitter.
- Copy all model-specific sound files to the target's SD card.
- Disconnect the target transmitter.
Note: If there's more than one point difference in version numbers for example 2.1->2.3, it's more reliable to convert the data in single-point steps 2.1->2.2->2.3. For this, you'll need to install multiple versions of Companion. The final transfer to the target need only be done after the last conversion.
Reporting 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.
