Following departure from the airport; I felt the airplane climb at an excessive angle. Further investigation revealed that the electric trim was in full 'nose up' position; and upon resolving the problem; my altitude was 2;500 feet. At that location; the floor of the Class C Airspace was 2;200 feet. I was in the Class C airspace (300 feet above the floor of the airspace) for 3 minutes and immediately proceeded to descend to a correct altitude. Based on in-cockpit ADS-B information; there were no other aircraft in the vicinity. I was the only pilot flying this particular aircraft on this day; and this problem was; at least partially; caused by a poor pre-flight inspection and not checking the trim position prior to takeoff.
GA pilot reported a Class C airspace incursion.
