A pilot who has recently stepped up to a larger, more powerful single-engine airplane than the two-seat model he flew in training is taxiing out for takeoff in the new make and model. Focused on managing the takeoff, with its less familiar operating speeds and sensations, the pilot commences the run, but soon finds the aircraft veering toward the left side of the runway because he has failed to add sufficient right rudder to counteract the stronger left-turning tendencies induced by the more powerful engine.
