I checked rudder pedal fit, as the pedals can be set rotated forwards or aft, and some builders have had trouble with the brake pedal making contact with the foot with the heel on the floor. I drilled through the lubrication holes with a #40 drill, and clecoed the pedals in the desired position. With the rudder pedal locked in neutral and the rudder blocked in neutral at the tail, I installed the rudder cables and installed return springs, which were cut down from some found at Tractor Supply - 1 inch diameter, .080 inch wire, 1.25 inch coil length.
