@Po-Fu:
To think it this way.
Why did TM stop producing Cougar, and even stop offering the spare parts?
Why did TM only want to offer F/A-18 grip, instead of the whole HOTAS?
The Realsimulator‘s F16 grip only is priced at €450, not including another €450 FSSB.
Why doesn’t Realsimulator offer F16 throttle as well?
The TAM(total available market)is tiny!!!
Even through molding with larger quantity, they as big/famous companies still can’t achieve the price you want, not to mention make a profit!
I’m going to take a stab and say the Cougar was developed in cooperation maybe with the USGOV. My first cougar was purchased from an F16 pilot that used it during his training and I believe a lot were used for that. When that well ran dry well as you stated above.
However finish your throttle and offer it as custom work. If no one wants to pay it’s no skin of your back.
I bought a Custom ICP for 400 ish and I absolutely LOVE it, same with rudder pedals and it was well spent.
Maybe your custom throttle is in my price range as well, remains to be seen, but i’m waiting ….
