Peck Aeroplane Restoration
The first problem was the radiator petcock unscrewed and the water ran out.
Another problem was a broken drive gear to the distributor (I think). They made a crude gear, flew it and it broke. So, they went to a machine shop and had a new one made.
Another problem was the tail skid broke and they had to make another. They departed last Sunday and arrived Friday.
