Because you need those two hats and the mouse nipple to be used as the China hat, Boat switch and the slew control. As you can see there aren't even enough hats on the X-55 throttle since you still need to bind the Coolie hat and the Mic switch. In my case, I'm using the rocker switch and the two buttons on the front of the throttle as a Coolie hat. That's a big turn off in this HOTAS setup and what really pisses me off is that this setup is supposed to be a step up from the X-65F which indeed has the hats we miss in the x-55
The dual stage trigger is not a big deal for me as the lack of rnpugh hats
