I agree with you, yet it does on the Bonanza in the sim it would seem. For example, from stationary, if I apply full rudder but no braking, the aircraft still turns around pretty much on the spot. In real life this would not happen without additionally applying pressure to that break. That’s how I figured that there must be some coupling of the brakes to the rudder in the sim. I may be wrong about what that value does exactly, but certainly adjusting that value gives me much more realistic rudder control down the runway.
