Brief Description: modelling multiple approaces to rudder/brake insta
After studying the three rudder/brake designs in various plan sets, I decided I need to set up models of the various approachesso I can see how they work. I started out by bending some scrap 0.032 sheet to model the rudder pedal brackets. These were too flexible so I moved on to using some extruded angles and some plate to represent the mounting points for the rudder pedals. the main decision point is that one design has the brake master cylinder centered behind the brake pedal and aligned with the rudder pedal vertical member. The other design has the brake master cylinder offset to the outside of the brake pedal, with the brake plunger rod anchored on one of the pivot mounts. I had the feeling this would cause some undesireable torque on the rudder pedals, so I decided to use the design that has the brake plunger rod anchored on its own dedicated mount on a pressure plate between the rudder pedal pivot mounts. I understand this adds some extra weight compared to the other design, but it's minor.
