I’m a little late joining this thread, but I do have a suggestion for modifying the rudder pedals.
Most builders have noted the pedals are at a very steep angle or in some cases reversed angle making it difficult to keep big feet off the brakes.
I fixed the problem by relocating the rudder and brake cylinder pivot mounts aft by 2 inches. This allows the entire rudder pedal assembly to rotate to a forward lean, yet keeps the pedals the same distance from the pilot. Now the pedals are at a natural angle. It takes a deliberate toe extension to apply the brakes.
