RC Groups OpenTX 2.0+ User Manual page 13

This page allows you to configure the trainer function for "master" use (make sure the Trainer mode in model
settings is set to Master). For each of the 4 main functions you will be able to set the mode (OFF, += for Add, := for
Replace), ratio and input channel.
Start by setting the mode for each function (the "standard" way is Replace i.e. when the trainer function is activated
the function is fully transferred to the student, Add allows both master and student to act upon the function
together). Then select the source channel accordingly to the brand/model of the student radio, and set the ratio to
100% for now. Now ensure the student radio is connected and recognised (moving the sticks of the student radio
should change the 4 numbers at the bottom of the screen) make sure all its trims are neutral, all its sticks are
centered (including throttle). Select the CAL field and press ENTER twice. The numbers should now be 0.0 or very
close.
Now move the student radio's sticks and check the numbers vary from -100 to +100. Should they reach those
values before the stick hits the end of its travel, reduce the ratio so that the throws match. Should they never reach
-100 to +100 even with full stick deflection, use the Multiplier field to increase it.
Trainer input is now configured. Note that this setting is global, because it depends on the student radio regardless
of the selected model. In order to use the Trainer function on a specific model you will need to assign the switch
you want to the "Trainer" Custom Function for that model. More about this further.
Version
This screen allows you to see the version of your currently loaded OpenTX firmware.
When reporting a bug, please be sure to include the revision number you see on the SVN line.
Diagnostics
The next 2 pages are the switch and analog diagnostics, they will show you what the firmware reads from the
radio's keys and potentiometers. This is the first place to go to if you run into issues with badly responding sticks /
pots / switches. If things are wrong here (inconsistent stick centering or end point readings, flickering value,...) then
you can be sure the problem is hardware-related and not due to wrong model setup.
The Analog page also features the battery calibration setting. It should be correct out of the box, but if not move the
cursor to the field, and adjust it so that the displayed value matches the voltage you can measure on the battery
terminals with a voltmeter.
