I was wondering the same.
Thrustmaster F/A-18 stick is perfect but the Warthog throttle is not close enough to F/A-18 hornet. A no go for me. I'm looking on the internet since months to find the perfect match, so frustrating(aerotronics, Winwing?). Just a set from Thrustmaster to change the buttons and UPGRADE the warthog throttle to F/A-18 hornet throttle would be great and I would buy the whole package the second it is on sale(anyway everything is sold out and prices are rising, we can see the consequence of Covid-19).
