Pete. Thank you for your response.
I do not have the 'No Reverse Zone' ticked in 4 throttles page.
However, I notice in the Users Manual under Joystick Calibration, there is a box 'IMPORTANT: Throttles for Wilco Airbus users (and possibly other Airbus add-ons)'. I guess the Aerosoft Airbus could well fall into the description in the brackets.
Understand what I need to do in the .ini file and change to 'Send to FS' and select 'Axis_Throttlen_Set' etc and calibrate. The fact is with 'Send to FSUIPC' and NOT calibrating, the throttles are fine.
So it comes back to the question (given that the AS Airbus falls into the 'Throttles for Wilco Airbus users (and possibly other Airbus add-ons))' category, can I somehow configure reverse thrust on these throttles using FSUIPC?
Thanks again for your attention, Pete.
