Honestly, I think the biggest thing is you can’t do a min radius turn smoothly in the sim. You have to kind of jerk the plane through the turn because the differential braking always makes it come to a dead stop at the low speeds required to execute that.
The travel angle of the nosewheel doesn’t bother me so much. I think if you made it go full travel with rudder alone, we’d end up off the runway a lot more often on takeoff or landing. It otherwise feels pretty realistic.
