Support/FAQ for Pro Templates

Last updated 23 Mar 2018

This page is for support of the pro templates. Here you can find out the recommended versions of OpenTx, how to migrate your templates to a different transmitter or to a newer version of OpenTx, and any current issues.

OpenTx versions

There are two separate branches '2.1' and '2.2'. Recommended stable versions of each:

Note: OpenTx 2.2.0 and OpenTx 2.2.1 (RC) are buggy and not supported by the pro templates.

Pro Templates FAQ

Supported transmitters

Which transmitters can I use with the Pro Templates?
X9D, X9D Plus, X9E, X10 and X12S
Can I use my Q-X7?
The Q-X7 is compatible with the F3F and Wingy templates. Others will require modification due to the X7's lack of sliders.

Compatibility with OpenTx 2.2.x

Will my setups work with OpenTx 2.2.x?
Current templates are fully compatible with OpenTx 2.2. Templates in 2.1 format are automatically converted to 2.2 format when opened in Companion 2.2.x, or the first time the transmitter is powered after flashing 2.2.x.
Older templates may appear to lose sounds after conversion, this is due to the 6-character limit for sound filenames in 2.2, which means that sound files with longer names are not recognised. To fix this for your template, go to the Special Functions menu, and identify all sound files in the 'Play Track' actions. In the SD card, shorten the names of these files to 6 characters + .wav. Then alter the references in Special Functions to match.
Servo centres shift after migrating to OpenTx 2.2
Two possible explanations:
1. Sticks/sliders not correctly calibrated. Calibrate and try again.
2. A known bug in OpenTx 2.1: channel values are not correctly calculated if PPM Centre has a value other than the default 1500µS. This is fixed in OpenTx 2.2. This means that, after migration, affected channels will have shifted centres. To eliminate the shifts without losing your trim settings: enter CAL mode, go into the Outputs menu, identify servo channels with values other than 1500 in the PPM Centre column, and adjust PPM Centre for correct calibration. On exit from CAL mode your trim positions will be restored.

Migrating to a different transmitter

Can I migrate my model data and radio settings to a different transmitter (e.g. X9D to X10)?
Yes, as long as the target transmitter has the same or higher major version of OpenTx, for example X9D/2.1 to X10/2.2 is OK, but X10/2.2 to X9D/2.1 is not. If migrating to 2.2, then please also read the section above.
Assuming you're good to go: back up the data from your old transmitter ("backup radio to file"). Start Companion and select a settings profile for the target transmitter. Open the backup; the model data is automatically translated for target transmitter. Transfer data to the target ("write models and settings"). Check that all knobs and sliders function correctly, if not then see below. Finally, recalibrate the sticks!
Sliders and/or knobs not functioning
The templates are targeted at the X9D. If using a transmitter other than X9D, you may find that mixer sources with LS, RS, S1 or S2 are not translated correctly and fail to work. The Setup Guides for all current templates have been updated with instructions on how to fix. For older templates, you can identify any broken mixer lines as follows: load original model into Companion, using a profile for the X9D/D+. Note down all mixers with LS, RS, S1 or S2. In the target transmitter, check if these mixer sources are translated correctly and amend in situ as necessary.

Other stuff

How do I re-order the servo channels (e.g. for mixed S-Bus/PWM operation)?
Re-ordering of servo channels can be done via a Lua script or manually. For more info see here.
How do I check for errors in my setup?
If you suspect you made a data entry error, then use Companion's 'Compare models' tool to compare your working version with a known good version.

Current Issues

There are no known issues affecting current templates when used with the recommended versions of OpenTx.
