I love that site. I learned alot by reading that before starting to build. Some humorous things in there too if you read through.
From the safety section:
When there is a guy at your field flying a fuel-soaked brick with ten times the power it needs, quarter-inch hinge gaps and field repairs all over the airframe do not fly with him. Keep your plane on the ground and your eyes on his because it is fast, heavy and dangerous. Why clubs let anyone put these missiles in the air I will never know.
