Narrative:

After an aborted takeoff; student incorrectly applied power to aircraft and failed to correct for left turning tendencies allowing aircraft to veer off runway into the grass and knocked over an airport sign and runway light. Student failed and refused to relinquish throttle to me (CFI); my application of brakes and rudder were ineffective in trying to overpower the student's applications. Damage [was] only to skin of leading edge of the starboard wing from impact with the sign. No power plant/prop or landing gear damage. Airport manager has students' aircraft insurance information for claim and repair of sign and light.
