Only 3 Trigulls were completed. #1 is C-FTRI, #2 was a static test airframe and never registered, and #3 is C-GATE. On one test flight, the pilot got her up to just over 30,000 feet.
C-GULL is registered in Ontario to an amateur built Jurca MJ5 G-2 Sirocco, which is a low-wing, retractable gear, tandem seat tail-dragger.
