overhaul pitch/roll control system

Apart from the crash-damaged parts of the Parson gyrocopter, some other linkages of its pitch/roll control system were found to be worn and/or distorted, so they have been overhauled and strengthened. Several new components needed to be machined/fabricated. As a safety precaution, all the control rod ends, bolts and bushes have also been replaced. Bruce was pleased that the progress inspection by a gyro expert went very well. It confirmed his decisions and provisionally approved the work that he had completed.
