I guess the Q2 had many variations in the beginning. A friend gave me his mechanical (cable) brake pedals (Q2) when he put in hyd. brakes. They slipped on my original Q1 rudder pedals easily. A hole drilled in the end of foot portion of the pedal allows a washer and a cotter pin to secure it. I had to go to motorcycle technology (a cable housing) to get the cable to the canard but it works well. SOME of you guys must remember the Q2 mechanical brakes. Dennis
