Controls assignments
In addition to default control assignments, our aircraft is using custom variables and events to manage all its systems.
Custom variables are called L Vars (prefixed with “L:”) and custom events are called H Events (prefixed with “H:”).
If you have external hardware and you are using specific software like FSUIPC or SPAD, you can assign buttons or switches to those variables and events.
In order to see custom variables related to the aircraft, you need to enable Developer mode (general options) and go to Tools > Behaviors > Local Variables on top menu bar. All custom variables are prefixed with “AZP_OV10” keyword.

However, changing those L VARS is not always enough and you may need to call the events described in the next section.
Custom events

Bind power levers with FSUIPC
Because of a simulator limitation, power levers cannot be bound to a controller axis using external software (FSUIPC, Spad, Axis And Ohs, etc.). A ticket as been raised to Asobo and we are waiting for a fix on their side.
In the meantime, a workaround has been implemented in order to move power levers using a L var, named L:AZP_OV10_THROTTLE_AXIS_EXTERNAL.
You will need to create a script to assign current axis value (-16384/+16384) to this L var, for each engine. The procedure is explained here for FSUIPC, but the same can be achieved with other software, please check their respective documentation.
You first need to locate events.txt file located in root FSUIPC folder (likely C:/FSUIPC7). Open the file and add the following lines on top:
//AzurPoly
AZP_OV10_Power_Lever_1_Set#@ (>L:AZP_OV10_THROTTLE_AXIS_EXTERNAL:1, number)
AZP_OV10_Power_Lever_2_Set#@ (>L:AZP_OV10_THROTTLE_AXIS_EXTERNAL:2, number)
Once file is saved, open FSUIPC and go to axes settings:

For left and right axis:
-
Select “Send Preset to FS” action.
-
Choose the correct preset (e.g. “AZP OV10 Power Lever 1 Set” for left engine).
-
Apply changes.

If needed, you can create a custom profile to apply this assignment only when flying the Bronco.
You should now be able to move power levers using your flight controllers.
