Just an FYI for now.
I have two
Saitek/TM Throttles on my system.
While they show as individual controls in WOTR/WOFF keyboard program, when I set up the controls on one, the controls are mapped to both.
I have not dug any deeper into this as yet.
Of course WOTR does not yet support dual throttles for multi-engine planes, I hope it might in a future update.
