These pedals are quite fussy with this sim for some reason. But fear not, they can and will work.
Originally I had a problem when paired with a VKB Gladiator K joystick. That solution can be found here
LINK I have recently bought a CH Fighterstick and Pro Throttle. So the option to connect the pedals directly to the joystick is no long an option. I decided to try the fix for VKB pedals that is in the WOFF BH&H FAQS, I was pleasantly surprised to see it work. All credit so the WallysWorld for discovering a tweak used in Star Wars Squadrons. Just one tweak is needed. In the VKB software, check off the box with the blue checkmark below (7 R). This reverses the axis to the correct directions.
Thanks Wally'sWorld, I'm glad I tried it.
The current fix in the WOTR FAQS, 9a) Binding VBK Pedals VKB Joysticks & RAVCORE JAVELIN Joysticks and others ? No longer works for VKB Pedals.
