I used to have an FLCS/TQS and it was a hell of a lot slacker than an F22, I found a thread on Cougar World and someone said the F22 was 20lb so I guess there's not a lot of difference apart from the weight of the handle helping a touch.
There are 8 screws on the base, 4 in each corner and 4 grouped just off centre, I don't know if these actually do anything on the Cougar as the tension wheel for the throttle is on the back, I'm thinking of opening mine up to change the detent positions tosomething that suits me better..another good design of the throttle IMHO and it does'nt invalidate your warranty.
IMHO one of the best new features is the mousestick which replaces the little rubber nubbin that the old TQS used to have. It feels like one of those ministicks on an analogue gamepad and can be depressed as a button. I originally tried to use it in conjunction with mouse control of the F8 pan view mode but I think there might be something amiss in AH as even with the stick unprogramemd to use the mouse, when I switch to the F8 pan mode view and have the mouse mapped to pan the view the view automatically switches to the up-right position. To get around this I've mapped the microstick like a POV hat.
Had a lot of fun programming this stick, my FLCS/TQS died a while ago so I had to get used to all the commands again and button position but the wizards in the FOXY software meant I did not pick up the manual for days, and only then did I need it to read up on axis programming.
If you have not already seen thissite SOB then take a gander at
Cougar World which is a fan site hosted by Frugalsworld and maintained by James Hallows who wrote the FOXY software. The forums are quite lively too and if you get any problems there are plenty of people there to help.
