Narrative:
While flying at 1;100 MSL smoke and a burning wire odor were noticed in the cockpit by my copilot/instructor. He immediately took over and turned back to the east toward the airport. I told ATC that we had smoke and were going to do a precautionary landing. ATC asked if we were declaring an emergency but the instructor shut off the master switch as part of his checklist to keep electricity from flowing further. Once close to the airport we turned the master switch back on briefly and told ATC we were going to land there and then we called them after landing. Issue seems to be bad capacitor related to the generator and the plane is currently grounded and being reviewed by avionics expert.
