Aircraft
Aircraft rolled on the runway and the pilot flying applied full power. After rotation; engine began running rough and the airplane was climbing at 100 FT/min. The airplane climbed to 400 FT over the runway and stopped climbing. Engine continued to run rough and Instructor on board decided to return for a landing on the active runway. The pilot flying turned right crosswind; and the Instructor advised the Tower that the airplane had trouble climbing. We made right traffic at 400 FT and made a short approach; landing on the active runway. The aircraft landed safely and taxied to a maintenance facility.
A C-150 engine began running rough after rotation permitting a 100 FT/minute; so the pilot turned downwind at 400 FT to land on the active runway while the Instructor advised ATC about the flight's difficulty.
