Support/FAQ for Pro Templates

Last updated 13 November 2020

This page is for support of the Pro templates, though some of the material may be of general interest. Here you can find out which transmitters and OpenTx versions are supported, any known issues, and how to migrate your setups.

Transmitters for the Pro templates

• The FrSky X9D, X9D Plus, X9E, X10, X12, Jumper T16 and Radiomaster TX16s are compatible with all the Pro templates.
• The FrSky Q X7 is compatible with the F3F, Wingy, Wingy4S and Ahi templates. Other templates will require modification to work with the Q X7.

OpenTx versions and status

There are three branches of OpenTx in common use:

OTX 2.3.x

• All templates are compatible with OpenTx 2.3.5 and later. 2.3.9 recommended.
• Avoid 2.3.8 (critical bug in Companion), RCs and nightly builds.

OTX 2.2.x

• All templates are compatible and tested with OpenTx 2.2.1 and later.
• Avoid 2.2.0, RCs and nightly builds.

OTX 2.1.x

• Old branch, version 2.1.9 recommended
• Some templates are not compatible, see template's version history.

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.

I can't find the GVARs menu!

There's no dedicated GVARS menu on the Q X7, X-Lite, and X-Lite Pro. Instead, GVARS are set in the Flight Modes menu. For 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?

Re-ordering of servo channels can be done via a Lua script or manually. For more info see here.

I think I've pressed the wrong key - help!

If you suspect you made a data entry error in Companion, then there's no need to start again. 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 the template for another transmitter: launch Companion, select a profile for your transmitter, and open the template. Ignore any warnings about incompatible formats.

Starting with version 2.2.2, Companion displays warnings if it detects issues during the conversion. Usually no action is needed. In the example below, four mixes need to be verified; no correction is required since the 'old' and 'new' columns are identical.

Transferring model data to another transmitter

At some point you may want to transfer all your models to a second transmitter. This is quite easy to do. 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 must 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.

1. Start Companion, select a profile for the target transmitter (create a new profile if necessary, remembering to select the correct radio type).
2. Connect the source transmitter by USB and choose "read models and settings from radio".
3. Check any conversion error alerts, make a note of what needs to be fixed.
4. Disconnect the source transmitter.
5. Connect the target transmitter by USB and choose "read models and settings from radio". This will open a second window.
6. Drag your models from the source window to the target window.
7. Close the source window. There should now be a single window open for the target transmitter.
8. Choose 'write models and settings' to update the target transmitter.
9. Copy all model-specific sound files to the target's SD card.
10. 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.
