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.
