The private pilot stated that the tail-wheel equipped airplane started to veer left during the landing roll out in calm wind conditions. In an attempt to bring the airplane back to the runway centerline, the tail of the airplane started to rise off the runway and he "got too aggressive" with the brakes. The airplane nosed-over on to its back, which resulted in substantial damage of the vertical stabilizer, left wing tip, and fuselage. The pilot said there were no mechanical issues with the airplane or engine that would have contributed to the accident.
