I discovered it at the first hard turn out of the FBO. I have a good friend who is the chief pilot for a firm out of the southeast who has a Beechjet in their fleet. He likes to do everything on one engine, not even starting the second until #2 for departure. Well, he was cleared for an immediate departure one day and forgot. He was busy trying to spool up 5000' down the 10,000' runway. He used almost every foot.
Most brakes on exec jets are very bitey when taxiing. In citations I rarely steer with the nose wheel. An occasional nudge on the brake on one side or the other steers just fine.
