I put castle nuts onto each end of the pivot rod on the brake pedals and secured them with cotter pins (this normally takes one bolt on each side, but I threaded and drilled a brass rod so it's a single piece and won't bind with flexion as easily).
The bottom (top in the picture) of the brake cylinders have a tab that bolts to the brake pedal arm. For some reason that tab is curved on one side and the plans call for a stack of washers to fill the space. I don't like how the washers let the cylinder rock around, so I printed a spacer with a concave surface to match the cylinder shape. I was short two bolts, so have to wait for a hardware order to arrive before I can finish the other two pedals.
The FlyLeds wing and tail light kit arrived. It's hard to believe that these tiny LEDs can possibly put out enough light, but apparently they're pretty incredible. Lots of soldering to do first though!
